hi and thanks for your report!

to me it looks like erase is also failing. your -VE log shows:

> Erasing and writing flash chip... Trying erase function 0... 0x000000-0x01ffff:E, 0x020000-0x037fff:E, 0x038000-0x039fff:E, 0x03a000-0x03bfff:EERASE FAILED at 0x0003a705! Expected=0xff, Read=0xfd, failed byte count from 0x0003a000-0x0003bfff: 0x39

then writing will fail too of course...
