Identical hex dumps (avrdude issue?) #101

Closed dennisdebel closed 3 months ago

dennisdebel commented 3 months ago

I have been dumping hex flash from several different Arduino Nano’s (328p), with very different code flashed to them and the resulting hex files are exactly the same. Problem is probably in chair and not avrdudess. This is on Windows 10. I am using an Uno as ISP and detection seems fine.

Searching the web for this issue does not seem to reveal any useful info. Am I reading the flash from the Uno? (I detect the 328p…). All these boards are clones.

Maybe the issue is with avrdude.exe, but not sure where to go from here.

Do all my Arduinos have their lock bits set? Or am I only reading the bootloader? (78KB seems a bit large for that)

Managed to make it work using a USBasp programmer instead of Arduino as ISP!
