Just4pLeisure 0:e0b964252a05 7 Whilst I have written this program myself I could not have done it without
Just4pLeisure 0:e0b964252a05 8 a lot of help and the original ideas and programs written by:

Just4pLeisure 5:1775b4b13232 31 Version 1.5 (04/2015)
Just4pLeisure 5:1775b4b13232 32
Just4pLeisure 5:1775b4b13232 33 Added since Version 1.4
Just4pLeisure 5:1775b4b13232 34 T8 CAN functions: DUMP, FLASH and RECOVERY
Just4pLeisure 5:1775b4b13232 35 Using modified T8Bootloaders that are slightly faster :-)
Just4pLeisure 5:1775b4b13232 36 Algorithms for different types of 5 volt replacement FLASH Chips in T5 ECUs
Just4pLeisure 5:1775b4b13232 37 AMD, ST and AMIC 29F010 types
Just4pLeisure 5:1775b4b13232 38 SST 39F010
Just4pLeisure 5:1775b4b13232 39 ATMEL 29C512 and 29C010
Just4pLeisure 5:1775b4b13232 40
Just4pLeisure 5:1775b4b13232 41 Changes since Version 1.4
Just4pLeisure 5:1775b4b13232 42 BDM FLASHing uses BD32 like Target Resident Drivers.
Just4pLeisure 5:1775b4b13232 43 Based on my 'universal scripts'
Just4pLeisure 5:1775b4b13232 44 BDM FLASHing much faster now
Just4pLeisure 5:1775b4b13232 45 Always use slow BDM clock function (bdm_clk_slow) for reliability
Just4pLeisure 5:1775b4b13232 46 Even when using the slow method it only takes 8 seconds
Just4pLeisure 5:1775b4b13232 47 longer to FLASH a T8 ECU.
Just4pLeisure 5:1775b4b13232 48 mbed library and compiler changes make it difficult to
Just4pLeisure 5:1775b4b13232 49 maintain the faster bdm functions that rely on software
Just4pLeisure 5:1775b4b13232 50 delay loops for timing.
Just4pLeisure 5:1775b4b13232 51 The file extension of the file to be FLASHed is now the more usual 'BIN'.
Just4pLeisure 5:1775b4b13232 52 i.e. 'modified.bin' instead of 'modified.hex'

Just4pLeisure 4:682d96ff6d79 57
Just4pLeisure 5:1775b4b13232 58 Added since Verion 1.3
Just4pLeisure 4:682d96ff6d79 59 Progress indication shown as a percentage, slightly slower but more informative
Just4pLeisure 4:682d96ff6d79 60 T8 BDM Functionality
Just4pLeisure 4:682d96ff6d79 61
Just4pLeisure 4:682d96ff6d79 62 Changes since Verion 1.3
Just4pLeisure 4:682d96ff6d79 63 T7 CAN FLASH algorithm changed to only send 4 Bytes at a time
Just4pLeisure 4:682d96ff6d79 64 Slightly slower but more reliable especially with I-Bus connection

Just4pLeisure 3:92dae9083c83 68 Version 1.3 (06/2011) - Basic T7 CAN support and faster T5 CAN bootloader
Just4pLeisure 3:92dae9083c83 69
Just4pLeisure 4:682d96ff6d79 70 Changes since Verion 1.2
Just4pLeisure 3:92dae9083c83 71 New T7 CAN menu provides some very basic T7 CAN DUMP and FLASH functions
Just4pLeisure 3:92dae9083c83 72 T5 CAN uses Mybooty version 2 for 1 Mbps CAN speed
Just4pLeisure 3:92dae9083c83 73 Get MyBooty version 2.x from forum.ecuproject.com
Just4pLeisure 3:92dae9083c83 74 Does not work with version MyBooty 1.x

Just4pLeisure 2:bf3a2b29259a 78 Version 1.2 (12/2010) - Only a very small update
Just4pLeisure 2:bf3a2b29259a 79
Just4pLeisure 2:bf3a2b29259a 80 Fixed since Version 1.1:
Just4pLeisure 2:bf3a2b29259a 81 My method of detecting the FLASH type didn't work for T7 ECUs
Just4pLeisure 2:bf3a2b29259a 82 Now that that I have corrected this bug it is possible to
Just4pLeisure 2:bf3a2b29259a 83 FLASH Trionic 7 ECUs using the BDM connection
Just4pLeisure 2:bf3a2b29259a 84 See the 'get_flash_id' function in bdmtrionic.cpp
Just4pLeisure 2:bf3a2b29259a 85
Just4pLeisure 3:92dae9083c83 86 Changes since Verion 1.1
Just4pLeisure 2:bf3a2b29259a 87 I have removed everything to do with the BDM DS connection
Just4pLeisure 2:bf3a2b29259a 88 I have changed the mbed pin number for the BDM DSO connection
Just4pLeisure 2:bf3a2b29259a 89 Now all BDM connections are part of the same MBED 'port'
Just4pLeisure 2:bf3a2b29259a 90 Being part of one port makes it possible to change all
Just4pLeisure 2:bf3a2b29259a 91 connections simulataneously so speeding up BDM
Just4pLeisure 2:bf3a2b29259a 92 See 'interfaces.cpp' for details of how the mbed pins connect.
Just4pLeisure 2:bf3a2b29259a 93 Uglybug's wiring circuit has these connections (thanks Uglybug)

Just4pLeisure 1:d5452e398b76 97 Version 1.1 (09/2010) - Still very crude way of doing things
Just4pLeisure 1:d5452e398b76 98
Just4pLeisure 1:d5452e398b76 99 Additions since Version 1:
Just4pLeisure 1:d5452e398b76 100 The BDM interface is now working
Just4pLeisure 1:d5452e398b76 101 Based on Janis Silin's BDM software with modifications and additions
Just4pLeisure 1:d5452e398b76 102 Detect which type of FLASH chip is fitted to work out type of ECU
Just4pLeisure 1:d5452e398b76 103 Modifications to FLASH algorithms - I think my algorithms are
Just4pLeisure 1:d5452e398b76 104 closer to the datasheet methods. Still to do:
Just4pLeisure 1:d5452e398b76 105 Separate pulse counters for 28Fxxx erase
Just4pLeisure 1:d5452e398b76 106 DQ7 and DQ5 checking method for 29Fxxx FLASH
Just4pLeisure 1:d5452e398b76 107 Works for T5.5 ECUs with 28F010 and 29F010 chips
Just4pLeisure 1:d5452e398b76 108 Probably works with T5.2 ECUs (chip detection method)
Just4pLeisure 1:d5452e398b76 109 MAY work with T7 ECUs ('prep' method may need changes - I can't test T7)
Just4pLeisure 1:d5452e398b76 110 NOTE: Some of Janis' original BDM commands may not work, or at least
Just4pLeisure 1:d5452e398b76 111 not as originally intended
Just4pLeisure 1:d5452e398b76 112 Lawicell CAN232 interface partially working
Just4pLeisure 1:d5452e398b76 113 Only a few Lawicell message types to open/close, set speed and write
Just4pLeisure 1:d5452e398b76 114 Trionic5 CAN functions
Just4pLeisure 1:d5452e398b76 115 All-in-one 'D' and 'F' commands to DUMP and FLASH BIN files
Just4pLeisure 1:d5452e398b76 116 Lots of checking for errors, either works or says it failed
Just4pLeisure 1:d5452e398b76 117 No need to interpret the cryptic CAN messages anymore
Just4pLeisure 1:d5452e398b76 118 Should now work for T5.2 and T5.5 ECUs
Just4pLeisure 1:d5452e398b76 119 Detects FLASH chip type and works out which ECU is connected T5.2/5.5

Just4pLeisure 1:d5452e398b76 123 Version 1 (04/2010)- The basic CAN functions are working
Just4pLeisure 0:e0b964252a05 124
Just4pLeisure 0:e0b964252a05 125 I have decided to 'release' this software somewhat prematurely because the FLASH
Just4pLeisure 0:e0b964252a05 126 chips in my spare ECU have 'died' and I don't know when I will be able to do
Just4pLeisure 0:e0b964252a05 127 carry on improving and 'polishing' it. This way others will be able to use and
Just4pLeisure 0:e0b964252a05 128 enhance it without having to wait for me.
Just4pLeisure 0:e0b964252a05 129
Just4pLeisure 0:e0b964252a05 130 For now, only option '5' Trionic ECU CAN interface is working. BDM and Lawicell
Just4pLeisure 0:e0b964252a05 131 CAN232 functions are dummies. The intention is to build a complete suite of CAN
Just4pLeisure 0:e0b964252a05 132 software for Trionic5, 7 and 8 ECU types as well as adding a BDM interface to
Just4pLeisure 0:e0b964252a05 133 make an 'all-in-one' USB programming tool.
Just4pLeisure 0:e0b964252a05 134
Just4pLeisure 0:e0b964252a05 135 To make this you will need an mbed system and the CAN circuit from this page:
Just4pLeisure 0:e0b964252a05 136 http://mbed.org/projects/cookbook/wiki/CanBusExample1
Just4pLeisure 0:e0b964252a05 137
Just4pLeisure 0:e0b964252a05 138 Some ideas for the truly creative and adventurous of you is to make a gizmo that
Just4pLeisure 0:e0b964252a05 139 doesn't even need to be connected to a laptop or PC to use, maybe even a self-
