2010-04-08 09:52:04     BF526-EZBRD NAND flash issue

>Hi,

 

I am experiencing some issues trying to load uClinux from NAND flash on the BF526-EZBRD. I have compiled u-boot (SVN head) with NAND flash support BFIN_BOOT_NAND and then programmed the generated image into parallel flash using VisualDSP. U-boot then boots correctly. Writing a uClinux image to NAND appears to succeed but the CRC check fails when uncompressing the image for boot. I've attached a log demonstrating a write/compare.

 

I suspect there may be an issue with bad blocks not being marked as such, given the warning on the 'nand scrub' command.

 

Any help appreciated

 

Andrew
