Just4pLeisure 3:92dae9083c83 3 trionic7.cpp - CAN Bus functions for Just4Trionic by Just4pLeisure
Just4pLeisure 4:682d96ff6d79 4 (c) 2011, 2012 by Sophie Dexter
Just4pLeisure 3:92dae9083c83 5
Just4pLeisure 3:92dae9083c83 6 This C++ module provides functions for reading and writing the FLASH chips and
Just4pLeisure 3:92dae9083c83 7 SRAM in Trionic7 ECUs. (Writing the adaption data back to SRAM not done yet).
Just4pLeisure 3:92dae9083c83 8
Just4pLeisure 3:92dae9083c83 9 Some functions need an additional 'bootloader' program to be sent to the T5 ECU
Just4pLeisure 3:92dae9083c83 10 before they can be used. These functions are: Identifying the T5 ECU type and
Just4pLeisure 3:92dae9083c83 11 FLASH chips, dumping the FLASH chips, erasing the FLASH chips, writing to the
Just4pLeisure 3:92dae9083c83 12 FLASH chips and calculating the FLASH chips' checksum.
Just4pLeisure 3:92dae9083c83 13
Just4pLeisure 3:92dae9083c83 14 My version of the bootloader, BOOTY.S19, includes some features not in other
Just4pLeisure 3:92dae9083c83 15 bootloaders; identifying the ECU and FLASH chip types, a 'safer' way of dumping
Just4pLeisure 3:92dae9083c83 16 the FLASH chips and the ability to program AMD 29F010 type FLASH chips
