Thanks to all so far..

Apparently Leon's test rom is useless to a locked MPU... will only help if the board boots or patially boots...

I have read Clays guides over and over and tried numerous things.

I think i will get you Nino to come around and have a quick squizz... Time permitting of course...

Could it be as simple as replaceing one of the caps Gavin ?
