The CANape demonstration version (>=2.0) may be run together with CCPSIM without hardware using the virtual CAN channel feature of the Vector Application CAN drivers. Ask for the latest CANape demo or visit our web site on www.vector-informatik.de Please contact us for samples with flash programming for Siemens C167, Motorola HC12 and Hitachi SH7055. -------------------------------------------------------------------------------- Notes: ------ - More information on ASAM/ASAP activities and documentation are available on the internet at www.asam.de - The ANSI C CCP driver sourcecode has been used on different platforms: Borland C++ Microsoft Visual C++ Tasking C16x Keil C16x Cosmic HC12 Hiware HC08 Hitachi Hew We try to keep the code as portable as possible. Please give us a note, if you run into a problem on another platform. - There is a workaround in function ccpWriteMta due to a code optimizer bug in COSMICs HC12 compiler. - The driver is restricted to a unique number of ODTs in all DAQ Lists. - The driver does not return the current MTA in the responce to a DNLOAD command. -------------------------------------------------------------------------------- Flash Programming: ------------------ The CCP standard provides support for Flash Programming by the commands CCP_PROGRAM, CCP_PROGRAM6 and CLEAR_MEMORY. This assumes that the complete Flash Programming functionality is integrated into the ECUs CCP driver. An alternative approach is downloading the Flash Programming function into the ECUs memory only when they are needed. The Vector CCP sample CCP driver and CANape provide this as an additional option to the standard CCP method. To enable this option in the ECU CCP driver #define CCP_BOOTLOADER_DOWNLOAD #undef CCP_PROGRAM has to be added to CCPPAR.H There will be two new, non standard CCP commands: CCP_PROGRAM_PREPARE BYTE 0x1E BYTE ctr WORD size This command anounces the beginning of the code download. MTA[0] contains the memory address to where the download will be done. size is the number of bytes which will be downloaded. The ECU has to make sure that the given memory range is free and the donload does not interfere with the ECUs normal operation. The sample CCP driver will call a function named ccpDisableNormalOperation( addr, size ) when this command is received. CCP_PROGRAM_START BYTE 0x1F BYTE ctr WORD reserved WORD croId WORD dtoId This commands starts the downloaded routine at memory location MTA[0]. croId and dtoId are the CAN identifiers to be used from now on. Both new commands are protected by the seed and key CAL resource. After executing the CCP_PROGRAM_START command, only the CCP commands CCP_SET_MTA,CCP_PROGRAM, CCP_PROGRAM6 and CLEAR_MEMORY may be supported. CCP_PROGRAM(size=0) should perform a software reset. CANape will then automatically reconnect to the ECU. CANape defines a file format containing Flash Programing routines. The extension is .FKL. The file may be specified in CANape's driver setup dialog for CCP or in CANape.INI: FLASH_KERNEL_FILE_NAME=c16x.fkl The FKL file look like this: [FLASH_KERNEL_CONFIG] FLASH_KERNEL_NAME="C16x" FLASH_KERNEL_COMMENT="Flash Kernel, C167, AMD 27064 FLASH, XRAM" FLASH_KERNEL_FILE_ADDR=0xe000 FLASH_KERNEL_SIZE=0x07ff FLASH_KERNEL_RAM_ADDR=0xe000 FLASH_KERNEL_RAM_START=0xe00e [FLASH_KERNEL_DATA] :20E00E0088D088C008D4A8CDD4D0020008D6A8DDDA0018E498C098D088C0F0DD0802DA0069 :04E02E00EEE3DB0042 :20E03200F0DDF0CCDA001CE6DB0088808860F08DF4C004003D23F06CDA0018E5E15C29C1AF :20E05200E6FC60EA28C1088148C03DFC49C03DF7DA00BEE40D1588F088E0D4D00200A8C006 ... The FKL files have to be located in the CANape \EXEC directory. CANape will then automatically find them and provide a selection in the CCP driver setup dialog. If "Direct" is selected, CANape will use the standard CCP approach. -------------------------------------------------------------------------------- Integration with Vector embedded CANdrivers: -------------------------------------------- 1. File Please link the following files to your application * ccp.c - CCP driver * ccp.h - Header * can_ccp.c - Interface between CCP und Vector-CAN-Driver 2. Messages Your CANdb must contain the CCP messages, a transmit message and a receive message. For example: TX: CCP_DTO 8 bytes RX: CCP_CRO 8 bytes Note that both messages have a length of 8 bytes. Please define a dummy data byte at byte position 7 to avoid optimization in older generation tool version (bug). 3. Generationtool settings * In "Node Options" activate 'use CCP'. * In "CCP settings" enter: - Stationaddress. - Select the names CCP messages. - Select 'Synchronous data acquisition" if required. Set MAX_DAQ to the number of event channels. Set MAX_ODT to the number of messages per channel. Activate the TX-Queue, minumum size is MAX_DAQ*MAX_ODT. - Activate "Checksum Calculation" if Offline Calibration is required. - Activate Flash Programmierung if required. - Activate Flash Seed&Key if required. 4. Application * #include "ccp.h" if you need to call CCP driver functions. * Call ccpInit() on Power On Initialisation. *
