We are currently in the process of developing an ARM9 board based on LPC3000 board and are currently having problems with NAND.
The NOHAU bootloader + blinky DEMO works perfectly on the LPC3000 and I can flash it and reset it without problems.
However when I download the NOHAU example to our own board µVision reports
"Flash Download Failed during verify" .....
If I turn 'Verify' off in the 'Flash Download Setup' then the error message goes away.
I am now at my wits end as to what the cause could be. Does this sound like a hardware or software problem?
