Dear All,
I am having the problem with Intel Flash TE28F640 J3C120 on my avnet evaluation board (xilinx based with Virtex-4). I have compiled successfully u-boot-1.2.0 and it run well without FLASH support. Eventually I want to store u-boot in Flash but when I compile u-boot with Flash support the u-boot fails during Flash initialization.
My Flash memory is: type: TE28F640 J3C120 (http://www.datasheets.org.uk/datasheet.php?article=3266188) vendor: Intel spec: NOR FLASH 64 Blocks 64 Mbits x8/x16
To support Flash memory I have configured u-boot with the following settings:
#define CFG_FLASH_BASE 0xFF800000 #define CFG_MAX_FLASH_BANKS 1 #define CFG_MAX_FLASH_SECT 64 #define CFG_FLASH_CFI 1 #define CFG_FLASH_CFI_DRIVER 1
The u-boot was compiled successfully but when I booted it I have got the error messages when it came to the Flash initialization:
U-Boot 1.2.0 (Sep 6 2007 - 17:56:34)
