If your cable is a pure level translator (RS232-TTL) it should work. Have you reprogramed your flash eprom via diag connector? Maybe you can give a more detailed discription. if I had known Ive ordered the new flash eprom already. According to what you say I could have simply used my cellphone serial cabel to reprogram the flash eprom (I used it to flash my router once)? Ouch. Good thing is that the DSP memory is on socket and can easily be programmed in a programmer. (best to check.if it's labeled SA35 it must be upgraded and if it's SA35 FTW it contains lastest DSP software)ĭSP memory is OTP device and must be replaced by a new IC. IF the module build date is < 2002 then the DSP memory and i2c eeprom must be programmed also. Basically all can be upgraded to the latest version software but only some just on diag connector.īesides main OS on 29f400 there's still DSP memory (the PLCC packaged chip near OASIS DSP) and an i2c eeprom memory (at24c64). Bootstrap is hardcoded you cannot alter bootstrap code by misuse or software mistake. USB to serial converter can be used where hardware com port is not available. HSE-Electronics the competence in embedded systems, C166- and CAN-Application.Ĭ161CS, C161JC, C161JI - Infineon TechnologiesīM54 is I nfineon c16x based which supports bootstrap loader on serial interface. It can be made through red diag connector on main pcb. In circuit programming of flash memory (29f400) is possible, you don't have to de-solder it. If you go ahead with this, can you post back to let everyone know, as it will probably be a couple of months before I can get around to it. I would suggest burning to a new fresh 29F400 so that you have the old one to go back to if something goes wrong. True USB Willem EPROM BIOS FLASH universal programmer (eBay item 310291769368 end time 30-Mar-11 05:10:24 AEDST) : Industrial I've been looking at Ebay for programmers, and found this one which should do the trick (no guarantees, do your assessment) but you will also need an adapter from the same source for the TSOP48 or PSOP44 package. (i think!!!, I'm not yet proficient at attaching files to posts ). This appears to be available in either of TSOP48,PSOP44 package formats. Notes: PICC v7.This is just from research, and I haven't checked by pulling the BM54 out for a look yet.įrom earlier in this thread, it is indicated that the EEPROM chip is a 29F400. My compiler could not generate the proper machine code from C-source (I think newer versions from Hi-Tech fixed this), so I wrote it in assembly (yuck!).
