James,
Please do not use CFG_BOOTSZ for flash size.
Since you have two 32MB flash chips tie to one chip select to use as one for 32-bit access (addr&data). The sectors listing will become 64KB, 64KB, 64KB, 64KB, 256KB... from 32KB, 32KB, 32KB, 32KB, 128KB... (one upper 16-bit data for flash 1 and one lower 16-bit data for flash 2) Based on your information provided, your environment data is assigned to first sector at offset 0x2000. Your environment data has to assigned to one of the 64KB sector, last 64KB sector will be the perfect choice.
U-boot 1.3.3: #define CFG_ENV_OFFSET 0x30000 /* must be sector aligned */ #define CFG_ENV_SIZE 0x2000 #define CFG_ENV_SECTOR_SIZE 0x10000
U-boot v2008.10: #define CONFIG_ENV_OFFSET 0x30000 #define CONFIG_ENV_SIZE 0x2000 #define CONFIG_ENV_SECTOR_SIZE 0x10000
I'm confused. Are you saying I need to apply these 19 patches to
address the problem I'm having? The 19 patches are for next u-boot release.
