This may be the wrong forum to post in, so moderator(s), move it if you need to.
I have an STK-500. One of the I/O pins (used for HV-programming) on the on-board 8535 is blown. The AT90S8535-8AC is unavailable for purchase or sample from the standard sources.
I have asked ATMEL if a "blank" AT90S8535-8AC can be used and the firwmare reloaded ... or... if an ATMega8535 can be used as a replacement.
ATMEL tech support says "yes" to new AT90S8535-8AC but "no" to ATMega8535 (because of different signature bytes).
I had also asked if ATMEL could supply the source or HEX file for the on-board AT90S1200 (used for firmware upgrade), which I could disassemble and possibly recode the signature and fuse bytes but the ATMEL answer is "we cannot provide the HEX file for the AT90S1200". I suspect the lock bit is cleared so no firmware reading.
So, my post is this: Anyone have any AT90S8535-8AC available for trade or purchase (at a reasonable cost)?
Or perhaps the source/HEX code for the on-board AT90S1200?
