Hello,

We are using a Zynq SoC on a custom Board. We are trying to use a NAND-Flash (MT29F8G08ABABAWP-IT) to store the Xilinx First Stage Boot Loader, U-Boot, Kernel .... We are having trouble to use the NAND-Flash in U-Boot. Currently we are using U-Boot 2012.04.01-00304-g7639205-dirty. and I get the Messag: NAND: No NAND device found!!! nand_scan_ident for NAND failed

I enabled CMD_NAND in the specific config file: #define CONFIG_NAND_ZYNQ #define CONFIG_CMD_NAND #define CONFIG_CMD_NAND_LOCK_UNLOCK #define CONFIG_SYS_MAX_NAND_DEVICE 1 #define CONFIG_SYS_NAND_BASE XPSS_NAND_BASEADDR #define CONFIG_MTD_DEVICE

I also tried an older version of U-Boot (U-Boot 2011.03-dirty) before where I got the Output:

NAND: No oob scheme defined for oobsize 224 No oob scheme defined for oobsize 224

I also enabled the CMD_NAND as before. When I look into the sources I only see oob_schemes defined for 128.

Has anyone tried to use a NAND-flash with the oobsize of 224? Is there some configuration missing? Besides the CMD config, I did not change anything else for NAND-Configuration. Am I missing something? The NAND-Flash has been tested with the Xilinx Drivers and it works.

Thanks, Regards, Peter Niklas
