I will re-check the SDRAM=20 > initialisation and UPM programming. >=20 Wolfgang, The solution was a lot simpler, there was no problem with the SDRAM initialisation. The cause was due to the fact that I had a BDI2000 = connected and the SYSIE bit was enabled in the DER for flash programming. Clearing = this bit solved the problem, probably a typical novice error :-) Regards Chris Down
