Hi all, I'm trying to use urjtag to erase, then flash to this setup (below). Sorry, tjtag output follows - I could never make urjtag properly recognize the processor, so no print command is available to me in urjtag .
Anyway, the erase does apprear to complete all 35 blocks of this 2MB chip but when I try to dump its content and look at it with a hex editor, I see 0xF7FF on most BUT NOT ALL addresses. Some block and sometimes just individual addresses do have the 0xFFFF that I'm expecting.
What do you think could be causing it and how to remedy it?
So, below is that hardware printout. The cable is unfuffered dlc5.
Thanks!
