Hi guys,

Today I tried to "patch" my 032DK ecu with my self-made asm code. The main reason was to learn something new. After I flashed my ecu with patch binary engine started normally but after couple of seconds ecu bricked itself. I tried disconnecting baterry but it didnt help. I'll try to flash it in boot mode but now its like -10 degree celcius and 3am so I'll do it in two days. But one thing don't let me sleep now. Is that possible to brick ECU forever with wrong asm patches, I mean something like damaging physically anything in circuit.

Extremely unlikely, but possible.

The #1 thing you can blow out is the ignition drivers.

Flashed original bin back and ecu is alive, surprisingly I didnt even had to do it in bootmode because ecu partially booted after being powered off for a night and was able to get into bootmode by obd.

What you try to change, and where you put your code in BIN? If that is not secret?

nothing really special, it was just for practice (press brake and gas pedal to flash MIL)
