2 Hardware Description

In this chapter, the function blocks of the ETKP20.0 are explained in detail.

2.1 Architecture

Fig. 2-1 "ETKP20.0 Architecture" shows the blockdiagram of the ETKP20.0.The microcontroller can read via the BGA connector from one of the two pagesof the data emulation memory and can write its data directly to the measure-ment data memory. These two memories (data emulation memory, measure-ment data memory) are using the same address space and are realized insidethe same DPRs.

Fig. 2-1 ETKP20.0 Architecture

Through the BGA connector the microcontroller can communicate with otherexternal memories or peripheral components of the development ECU.

While the microcontroller accesses the program data (not the program code)out of the data emulation memory, the content of the data emulation memorycan simultaneously be modified by the calibration and development systemthrough the serial ETK-interface. This process enables adjustments of parame-ters, characteristic lines and maps through the calibration and developmentsystem. Using an additional measurement data memory area, the ECU micro-controller can send data to the calibration and development system whichreceives, buffers and processes this measured data.

A flash memory is available for permanent storage of the adjusted parameters(program data).

Hardware Description 11

12

The 100 Mbit/s serial interface provides communication with the calibrationand development system.

The power supply for the ETKP20.0 is provided by a switch mode power sup-ply, to minimize power dissipation.

2.2 Microcontroller Interface

The whole microcontroller interface to the calibration and development systemmemory has a 16 bit wide data bus and uses only one chip select for read andwrite accesses.

Fig. 2-2 System with internal and external Memory

The processor can read and write its data directly from or to the data emulationand measurement data memory. Fig. 2-2 "System with internal and externalMemory"shows an overview of the system with "on chip" Flash and RAM andexternal Flash and RAM memory. It also shows the possibilities to access thedifferent memories with its chip selects. The chip select of the data emulationand measurement data memory can be choosen from (/CS0, /CS1, /CS2, /CS3)with the "ETK Configuration Tool" (see Chapter 4 "ETK Configuration"). Forpurpose of braindead flashing the ECU /CS0 can be assigned to one of themicrocontroller chip select signals (/CS0, /CS1, /CS2, /CS3).

Hardware Description

2.3 BGA Connector

The BGA connector interfaces the ETKP20.0 with the ECU. All signals of themicrocontroller are directly connected to the BGA connector with the exeptionof /CS0 (see Chapter 2.2 "Microcontroller Interface"). Also the clock signalmust be provided through the connector to the MPC5553/MPC5554/MPC5566.

2.4 Data Emulation and Data Measurement

The complete data emulation and measurement data memory consists of two1 MByte pages (Fig. 2-3 "Data Emulation and Measurement Data Memory: 2Pages with 1 MByte each"). The address range of the data emulation and mea-surement memory must be 1 MByte and it must be defined at a 1 MByteboundary.

Data emulation memory and measurement data memory must be locatedinside this 1 MByte address range. The segmentation of this address rangebetween both memory parts is variable.

The measurement data memory and data emulation memory can have variablesize and offset addresses inside this fixed address range.

2.4.1 Data Emulation Memory

During operation of the ECU, only program data, not program code, can bemodified by using the data emulation memory. Modification of program codecould lead to a system crash. The program code is continuously processed outof the internal or external memory.

Reference data can be stored on one page ("Reference page") while the dataon the other page ("Working page") can be modified. It is possible to switchbetween the two pages during operation through the application software.

2.4.2 Measurement Data Memory

The measurement data memory must be located within the address space ofthe data emulation and measurement data memory. It can have variable size.

The measured data stored here can be transferred to the calibration and devel-opment system via the serial ETK interface.

2.4.3 Triggering of Measurement Data Acquisition

The exact procedure for capturing measured data is explained in the documen-tation Display Table 13; only the hardware-specific features are mentionedhere. The ECU microcontroller initiates a data acquisition task by writing anarbitrary value to the trigger address at the so called trigger segment. The soft-ware of the ECU is able to start different data acquisition tasks by writing dif-ferent trigger addresses (trigger 1 to trigger 32).

The ETKP20.0 contains a trigger comparator which can be configured to selecta segment of 256 Byte out of the measurement data memory address space(at a 256 Byte limit). This limit is known as the trigger segment address.Fig. 2-4 "Division of the 256 Byte Trigger Segment" shows the configurationof the 256 Byte trigger segment.

The ETKP20.0 provides an extended trigger segment with up to 32 direct 16-bit hardware triggers.

Note

Because there is no write protection of the data emulation memory possible, it must be taken care not to override emulation data.

Note

The unused address areas within the trigger segment are reserved for future applications and must not be used for other purposes.


Fig. 2-4 Division of the 256 Byte Trigger Segment

For ECU setup and debugging purposes, the ETKP20.0 can be disabled by writ-ing an arbitrary value to the approriate address (ETK_Disable) in the triggersegment. When disabled, write accesses to the ETK data emulation and mea-surement memory are not performed (with exception to the trigger segment).The ETKP20.0 data lines are in tristate mode, even during read accesses. Writ-ing to ETK_Enable enables the ETK.

The disable/enable state is volatile, i.e. after power up, the ETK boots up in thestate defined by the "ETK Configuration Tool" (ETK state after power up).

2.4.4 Data Retention in Data Emulation Memory

The data emulation and measurement data memory physically consists of astatic Dual Port RAM and is permanently supplied with power from the carbattery, to guarantee that data is preserved even when the ignition is switchedoff. If the ECU with ETK is isolated from the battery, all data will be lost.

2.5 Data Flash Memory

Flash memory is provided on the ETKP20.0 for permanent storage of emula-tion data. Users can copy the contents of the data emulation and measure-ment data memory into the flash memory using the operating software. It isrecommended that an updated data set is always stored in the flash memory.

The ETKP20.0 has a circuit which recognizes and stores power failures. If thiscircuit detects power failures, and therefore a possible inconsistency of theemulation data, the ETK microcontroller initiates a copying procedure fromFlash memory to DPR upon restart. The Flash memory data is copied to bothemulation pages. A green LED on the ETK displays the status. The operatingsoftware announces the procedure by a message in the status line.

If the ETKP20.0 is used as a normal RAM it may be useful that this copyingprocedure is switched off. This can be done

• by doing a write cycle to a dedicated address in the trigger segment (trigger segment address + 0x008h, see Fig. 2-4 "Division of the 256 Byte Trigger Segment") or

• by setting the configuration parameter ETK Usage as with the "ETK Configuration Tool" to the states "RAM adaptor not initialized" or "RAM adaptor initialized" (see chapter "Configuration Parameter" on page 30).

The green LED on the ETK will be switched off.

2.6 Code Flash Memory

The program code is not emulated by the ETKP20.0. The program code isstored in the ECU Flash memory ("on chip" and/or external) and is not modi-fied by the ETKP20.0. Only the accessible emulation data areas are emulatedby the ETKP20.0. The ECU Flash memory can be programmed with the normalFlash memory programming tools.


2.7 Power Supply

Fig. 2-5 Power Supply Connectors CON2 and CON3

The ETKP20.0 needs a permanent power supply. It is powered directly from thecar battery. The input voltage may vary between 4.3 V and 18 V.

The ECU voltage (VDDE2/3) is monitored by the ETK to recognize whether theECU is switched on or off. In case of higher input voltages to the ETK an addi-tional voltage converter is required. All necessary voltages are created throughswitching power supplies which minimizes heat build-up. The power supply ofthe ECU is not affected by the ETKP20.0. An automatic switch ensures that thepower supply of the ETKP20.0 is automatically switched on and off.

The ETKP20.0 can be supplied with power through the 2-pin power supplyconnector CON2.

Additionally the through-hole solder pad CON3 can be used to connect apower supply UBatt2. The power supply on CON3 must use the GND of CON2(refer to chapter 3.2.2).

2.8 Serial ETK Interface

The serial 100 Mbit/s ETKP20.0 interface creates the link to the calibration anddevelopment system. The ES1232-A board for the ES1000 system and theES690 will support the 100 Mbit/s interface.

The interface utilizes a 100Base-TX transmission to achieve a transmission per-formance of 100 Mbit/s. It is not possible to use the old interface cable (for8 Mbit/s) with the new interface in the 100 Mbit/s mode.

• During initalization, this pin signals the debugger tool if JTAG arbitra-tion is required (TDET). The ETKP20.0 will pull the signal down with an internal 10 kOhm resistor, signalling that no arbitration is required.

• During operation, TDET/WDT may be used as optional watchdog dis-able control signal. It is driven by the debugger tool and controls an external hardware watchdog circuit on the ECU (see Fig. 2-9). The sig-nal is directly connected to the through-hole solder pad.

2.11 Braindead Flashing

In order to support braindead flashing the ETKP20.0 provides the hardwareprerequisites to allow booting the microcontroller from the ETK memory andmaking the flash accessible to the software while the microcontroller is run-ning from the ETK memory. For braindead flashing it is required that the micro-controller boots from the ETK memory.

When braindead flashing is initiated, the first step is to force the ECU’s micro-controller into a reset.

A valid boot programming code will be downloaded into the ETKP20.0.The ETK drives the BOOTCFG[1:0] inputs such that the ECU’s microcontroller isconfigured to external boot. Upon releasing the reset line, the RSTCFG pin isdriven low in order to force the microcontroller to accept the external ResetConfiguration presented on BOOTCFG[1:0]. The ECU’s microcontroller bootsfrom /CS0 (which is now the ETK CS) and executes the boot programming(recovery) code from the ETK memory. The recovery program code acceptsdata via the ETK mailbox and programs it into the internal microcontrollerflash. When flash programming is done, the microcontroller must be forcedinto reset again and the changes done before must be reverted. When reset is

Green On When the power supply voltage drops below 3.5 V, the data retention of the DPRs is not longer ensured. As soon as the ETK is switched on again, the content of the ETK-Flash will be copied into reference and working page RAM. The green LED stays lit until the calibration and development system copies new data into RAM.

Flashing ETKP20.0 is in RAM adapter mode. Measurement and calibration are not possible (in all "ETK usage as" modes except "ETK mode initialized")

Off Working page may be different to reference page.Working page and reference page may be different to the ETK-Flash.

Yellow On 100 Mbit/s communication to calibration system estab-lished

Note

During braindead flashing /CS0 must not be used by any memory device on the ECU.

LED State Meaning


released next time, the microcontroller takes its Reset Configuration fromthe ECU and boots from the standard boot memory (i.e. internal Flash) to exe-cute the recently programmed code.

To avoid bus contentions when the ETK drives the Reset Configuration theBOOTCFG[1:0] bus and the RSTCFG signal of the microcontroller must not behard-wired to VCC or GND or driven by a strong driver. Instead, the bus musteither be driven by a driver that is disabled when the ETK is driving the ResetConfigution or by weak pull-up or pull-down resistors.

2.12 Reset

The requirement for ETK reset mechanism is to ensure that power-up andpower-down behavior of ECU is clean and smooth and to prevent corruptionof data stored in the ETK.

To accomplish this the ETKP20.0 senses the VDDE2/3 of the ECU. This allows itto detect when the ECU is off and forward this information to INCA. In addi-tion, it allows the ETK to enter the power save mode with the CAL tool (ES590/ES591) unplugged. In addition, the ETKP20.0 senses the status of the /RESETand /RSTOUT lines to generate a write protect signal for its memory. Finally, theETKP20.0 generates a reset signal by pulling /RESET to keep the ECU in resetwhile the ETK is in power save mode and to prevent the μC from starting untilthe ETK is ready to work. The ETK is ready to work when it has finished itsinitialization after leaving power save mode or after initial power-up. This fea-ture allows it also to reset the ECU under tool control (required for INCA andProF) and to perform an emergency stop of the ECU in case of ETK failure.

Note

As the microcontroller's FMPLL mode selection signals PLLCFG[1:0] are not driven by the ETKP20.0, they must be driven to approriate voltage levels by the ECU during brain dead flashing. Refer to the microcontroller's reference manual for details.

4 ETK Configuration

In this chapter, the configuration parameters of the ETKP20.0 are described.

4.1 Overview

As already mentioned in previous chapters, some project-specific adjustmentsare necessary. Configuration data is stored permanently in a serial E²PROM.Generating a valid configuration data set is supported by the "ETK Configura-tion Tool". The "ETK Configuration Tool" contains information on all availableETKs. The user is supported through a graphical interface.

4.2 ETK Configuration Tool

Generating a valid configuration data set is supported by the "ETK Configura-tion Tool". The "ETK Configuration Tool" contains information on all availableETKs. The user is supported through a graphical interface.

The configuration is done in two steps:

1. Generation of the special address offset for the emulation and mea-surement data memory.

The location of data areas, measured data output areas, trigger seg-ment addresses etc. are familiar to the ECU software developer, or can be generated automatically. If an ECU description database (ASAP, ...) with the corresponding input exists, these inputs can be downloaded from this database. If necessary, a plausibility check is performed.

2. Connection of the ETK to the ECU.

The ECU hardware developer defines the connection of the ETK to the ECU. The corresponding signals usually have to be adjusted for each microcontroller. All inputs are checked for plausibility, to make sure that a valid configuration is generated.

The "ETK Configuration Tool" can create the following output:

1. Direct ETK configuration

2. Storage of the configuration in a data file

3. The corresponding ASAP input

The most important outputs are the entries for the ASAP file. The parameterETK_CFG is created and contains the complete ETK configuration of the ECUinterface in hex code. If this parameter is entered correctly in the correspond-ing ECU description file, it guarantees that every time the calibration system isstarted, the ETK is checked for the appropriate configuration. If necessary, theETK will be configured appropriately to the corresponding project.

ETK Configuration 29

30

4.3 Configuration Parameter

The configuration of the ETKP20.0 is possible with the "ETK ConfigurationTool". Not all combinations of parameters make sense. The "ETK Configura-tion Tool" provides support concerning the configuration parameters. The fol-lowing is a list with configuration parameters:

• Chip Select 0 (Mapped to /CS0, /CS1, /CS2, /CS3)

The Chip Select 0 of the ECU gets remapped to be able to place another memory area on the chip select /CS0. With this remapping the ECU can be forced to boot from the ETK memory and start a bootstrap routine for flashing. This feature should not be used by the user sepa-rately, but is only needed in the braindead flashing context.

The default value is "/CS0".

• ETK Usage as (ETK mode initialized, ETK mode not initialized, RAM adaptor not initialized, RAM adaptor initialized, ETK disabled)

This feature allows it to use the ETKP20.0 as a RAM extension. The possible states are

– ETK mode initialized: The ETK is used in the normal way. When using the ETK together with INCA this mode gets set when an ASAM-2MC configuration is written to the ETK.

– ETK mode not initialized: Normal ETK operation, but when a power fail occurs no data gets copied from the backup flash into the dual ported RAM pages.

– RAM adaptor not initialized: The ETK is used as RAM extension.

– RAM adaptor initialized: The ETK is used as RAM extension. If a power fail occurs the memory from the backup flash gets copied into the RAM.

– ETK disabled: The ETK is invisible to the ECU.

The default value is "ETK mode initialized".

In all "ETK usage as" modes except "ETK mode initialized" the ETKP20.0 is not in its normal operation mode, i.e. measurement and calibration are not possible.

Note

Do not use the ETKP20.0 together with INCA with any another state than "ETK mode initialized". Always reconfigure the ETK after is was used as RAM adaptor to avoid unexpected behaviour of INCA.

ETK Configuration

• Power-On State (Active/Inactive)

– Active: The ETK is enabled at ECU power on.

– Inactive: The ETK is inactive when the ECU power on.

The default value is Active.

• Chip Select for ETK (/CS0, /CS1, /CS2, /CS3)

Selects the ETK chip selects.

The default value is "/CS2".

• Use Nexus TOOL_IO2 as Watchdog (Yes, No)

The pin 27 (TOOL_IO2) is used as watchdog (see Fig. 2-9).

The default value is No.

• Boot mode (Internal, Serial, External Single Master, External Multi Master, Selected by ECU)

Selects from which memory the ECU boots.

The default value is Selected by ECU.

• Nexus/JTAG bus voltage (1.8V, 2.5 V, 3.3 V, Auto Detect)

Selects the Nexus/JTAG bus voltage, or lets the ETK detect the voltage.

The default value is Auto Detect.

• ECU bus voltage (2.5 V, 3.3 V, Auto Detect)

Selects the ECU bus voltage, or lets the ETK detect the voltage.

The default value is Auto Detect.
