AT91SAM9260 enable dataflash fails

Thu Aug 12, 2010 8:42 am

Hello,
I have my custom board equipped as AT91SAM9260-EK. I have USB and serial cables connected. I power up the device and "RomBOOT>" shows on terminal (115200 8n1n). But when I try "Enable NandFlash" on SAM-BA terminal shows crap:

RomBOOT

SAM-BA hangs up and says "not responding".

What goes wrong? Why RomBOOT shows up nicely but then only crap?

With the kit everything goes fine:

RomBOOT

Any help would be appreciated!

Biggest problem I have run into is attachment issues with the BGA. Try reflowing the AT91SAM9260, it is possible that some of the signals controlling the NAND Flash are not connected.
