Hi every body..
First excuse my bad English, and i am new on this forum, i hope that somebody can help me on this issue..

i have the nitron demo board 68hc908qt4, and i am trying to program it with a software that come with the kit (it use the A/D and the Led on the board ....

i can upload the code and program the flash, but when i attempt to verify the functionality on the board, nothing happen......

when i do full ship simulation with codeWarrior 5.7, it works just fine...

i saw on the net that maybe it is a problem with mon08 on the ship, or the array vector from $FFC0 to $FFFF(problem with the reset vector or something like that, but i am not able to reprogram the monitor code into flash...

Please help....
Thank you very much ...

Hello fidellyo,

The problem you are experiencing is probably due to a bug in the user monitor. This is covered in some detail within Engineering Bulletin EB615.

The error is associated with the user monitor CONFIG1 setting, and once it has occurred, unfortunately the user monitor (a corrected version) must be re-programmed, after erasing the entire flash memory.

Regards,
Mac
