Flash timeout

PierreYves Vincent

Hi,
When I flash my STR9, I receive the message box: " Flash Timeout. Reset the Target and try it again " and after this message, another one: " Flash Donwload failed - ARM9E "

I tried to flash my STR9 with the same project on 3 different computers, for two it is working but for one of them I get the messages written above.

Any suggestions ?
In advance thank you !
