Re: [U-Boot] Incorrect Chip ID for Micrel Nand Flash on AT91SAM9260 board

Hi Kevin,

I am working with a custom board based on the Atmel at91sam9260 arm processor with a Micrel 2 Gb Nand flash chip (mt29f2g08aadwp). However, when u-boot starts it reports the wrong Chip ID (0x01 instead of 0xda) and then I start getting Bad eraseblock messages during the rest of the boot process. The strange thing is that when I debug the board using a JTAG it gets the correct Chip ID and boots properly. I am hoping that someone else might have run into a similar problem, or might have an idea of how to proceed.

try sending a reset command to the nand before getting the ID, this should solve the problem.
