Trouble with NAND bad block table

yensid — Thu, 21 Nov 2013 14:03:49 GMT

Hi I'm working with a custom board based off of the P1010RDB. We are booting from NAND and are using Micron MT29F8G08ABABA as a replacement NAND. I can program the nand using jtag and uboot recognizes the NAND, after some minor changes. Uboot successfully boots to the command prompt. During boot "Bad block table not found for chip 0 No space left to write bad block table" is displayed and I cannot write to the nand chip from u-boot to save the environment or program new u-boot. The chip is 1GByte and has a 512K block size, and 4K pagesize with 224byte oob size.

If I run nand bad the whole flash chip is reported as bad.

Has anyone had a similar experiance? Any ideas what might be causing this?

Thanks for your help.

Thanks Yiping! :smileyhappy: That solved the issue.

I have a follow up question. NAND now fully works but on boot there is a message "fsl_ifc_read_buf beyond end of buffer (256 requested, 0 available)". This message originates from fsl_ifc_nand.c. Do you know what the cause of this message is?

Thanks again.
