The 512k is because I have used a double capacity chip when replacing mine. this is the max. for the footprint. > For my tests, I replaced the whole content of firmware_rec.bin with 0x55, > resulting in a 178.134 byte file.

Try flashing a file with a single zero byte, and check if it appears in multiple places. > It's a SST39VF020, should be the right one I hope. You didn't tell the speed grade, but Archos was already using the lowest, iirc. Jörg -- "Sie haben neue Mails!" - Die GMX Toolbar informiert Sie beim Surfen!
