Boot reading of EDC15 with Galletto v54
So this is a quick guide on how to read in bootmode on EDC15P ECU's. I hope some of you can use this too, as there are only guides for this with MPPS.
It appears however, that it's not possible to write the ECU in bootmode using this feature. I have at least not had any luck with it. Feel free to correct me if i'm wrong.
Step 1: Open the ECU
I did this carefully with a screwdriver
Step 2: Locate the 29f400 chip
This is where the flash is stored
Step 3: Fire up FGtech and go to Tools Boot Mode > Siemens-Infineon C167 > Bosch ME7 - 1 Micro - Flash 400 Boot Mode
Step 4: Connect the ECU like this without putting on power yet (On my pictures i have made an EDC15 to OBD adapter, but basically the same):
VAG_EDC15P_P+.jpg
Step 5: Press Read ECU now follow the instructions (Put ground on pin 24 of the flash > Apply power > Remove ground after approx. 5 seconds)
All gone well Galletto 4 should now read the flash.
I have attached some pictures for more detailed instruction.
Hope this can help somebody!

Hi. That's okay. But galleto sometimes doesn't do a good checksum. So it's better to count yourself in the modified file.

No need to read in boot mode.
Obd reading is identical to boot mode reading at this ecu. Flash I have 29f400.Mpps is perfect for tis ecu.

Galleto has this to you when you try to read in boot mode. This can sometimes damage the program. Even though you were only reading it. So we only use boot mode when something happens to the program and we do not normally communicate with the Mpps driver, it can get it back on its feet. Count the checksum, apply 1kOhm to pin 28 and ground. Set Mpps to recovery. And upload it and the driver should connect and work normally.
