-c write needed to write firmware (not -c verify):
- roundloader.exe -p COM1 -s 19200 -f aim2can_DB25_BMW.chex -c verify <= this will NOT write !
- roundloader.exe -p COM1 -s 19200 -f aim2can_DB25_BMW.chex -c write <= this is the command to write
- in case of problem, please report exact command and md5sum of the files (.chex and roundloader.exe files at least)
- try write (VT Tools/firmware/firmware upload, not the wizard method after replacing an old round.chex file under VT/... directory with the aim2can_DB25_BMW.chex file tweak-named as the round.chex), see AimCanFirmwareUpgrade
Hi, I'm currently trying to flash one unit (from VAG ?) to BMW specifications, I managed to get it into boot mode by sending file with loads of SSSS.
problem is that I can't upload fw to it. adding screenshots with problem.
argc: 9

Bootloader section pages in chex:
Speed: 19200
Port: COM1
BUFF:????■????■lCurrent State: UNKNOWN!! Exit!
Despite the (misleading) State: UNKNOWN message it actually seems to be a success, page55 is the marker word. After reboot, does it work ? Sending AIM data, every 5th byte is 0xA3 ?
will do some testing today, will check does stream actually changes. thank you.
ok, testing done. I'm not able to get it into boot mode using vemstune, only when sending SSS via terminal program.
vt detects it over round revive wizard that it's in boot mode after terminal program did it's job.
even vt detects it as boot mode it does not let you to upload fw to fix it, cause menus for that are inactive.
trying to do update over command promt makes same error as before and even you guys say that means success can stream does not change, after reboot it's still spitting aim stream ID's instead of bmw.
full command
roundloader.exe -p COM1 -s 19200 -f aim2can_DB25_BMW.chex -c write
