2010-01-29 11:34:54     U-Boot in NAND Flash

I have 2 boards. One board uses the Numonyx/ST NAND01GW3B2C NAND Flash and a BF526. I have U-BOOT loaded in the NAND flash and I boot from NAND flash without issue.


On the second board I have the MT29F4G08AAC NAND Flash and the BF525 (Rev 0.2). I use the same options when building U-BOOT but when I try to boot from NAND flash the board just hangs. I have verified that the nand interface works as I have been able to program u-boot into NAND.


Has anyone used the MT29F4G08AAC? Any issues? Any suggestions?

we've only tested ADI boards with booting out of NAND flash.  while any NAND flash that works with the on-chip NAND controller should work with the same, it doesnt mean there arent latent bugs.


can you connect JTAG to see where it's hung ?  what about booting over the UART and probing the flash from the command line ?

Hi Mike,


We have been able to boot u-boot over the spi interface (from spi flash) and then boot the kernel out of the NAND flash. We can then use the NAND flash as expected.


We have the following when building u-boot:
