Workspace is RAM. If your memory controller isn't set up, you can't use the workspace. From your config file it looks like you're planning on using some kind of cache for SRAM. I'd just skip this for now. Delete the WORKSPACE line and you should be able to write to flash. It'll be dog-slow, though.
This is of course probably due to my bdi2000 cfg file - I've annexed it in this email. I've tried to keep the file bare bones though this is my first time writing this config. I've got one flash bank, a 128MB spansion S29GL01GP . Here's my flash #DEFINE's :
For my 64Mb Spansion GL flash I use:
CHIPTYPE MIRRORX16 ;Flash type: Spansion CHIPSIZE 0x800000 ;The size of one flash chip in bytes BUSWIDTH 16 ;The width of the flash memory bus in bits (8 | 16 | 32 | 64)
Yours will probably be the same, but size will be 0x1000000. I'm assuming your flash is 128Mb and not 128MB, but I apologize if this is wrong.
#define CFG_BOOT_BLOCK 0xf8000000 /* boot TLB block */ #define CFG_FLASH_BASE CFG_BOOT_BLOCK /* start of FLASH 128M */
#define CFG_BR0_PRELIM 0xf8001001
#define CFG_OR0_PRELIM 0xff806e65
#define CFG_FLASH_BANKS_LIST {CFG_FLASH_BASE} #define CFG_MAX_FLASH_BANKS 1 /* number of banks */ #define CFG_MAX_FLASH_SECT 1024 /* sectors per device */ #undef CFG_FLASH_CHECKSUM #define CFG_FLASH_ERASE_TOUT 512000 /* Flash Erase Timeout (ms) */ #define CFG_FLASH_WRITE_TOUT 8000 /* Flash Write Timeout (ms) */
The hardware engineer I'm working with tells me our first challenge is to write the u-boot.bin file to flash. Can any anyone please help
