First, thanks for Wolfgang's reply to my last post.

I'am trying to make U-Boot work with the NAND flash on H2, that is I hope U-Boot can boot kernel from Nand flash. I copied the codes related to NAND from u-boot-1.1.1-h3 (which can be downloaded from linux.omap.com) to platform.S, cmd_nand.c, omap1610innovator.c and omap1610h2.h. Compiling was ok, but once I run the u-boot on H2, it entered an infinite loop at nand_init (which called nand_probe, then NanD_ScanChips, NanD_IdentChip, NanD_Command).

I found some macros (such as NAND_CTL_CLRALE) are defined as udelay(). It is ok for H2 or H3? Can anybody tell me whether the nand code works on H3? If yes, what about H2? Thank you.

Best regards, Dongyan Chai
