I had the same problem with an mpc8641. After emailing the Abatron folks they set me straight.
There's probably a line in your bdi config file like this:
WORKSPACE 0x00002000 ;workspace in SDRAM
Comment that out. The BDI uses a little chunk of the processor's RAM to speed up flashing and whatnot if you include that line. But if you don't have a valid RAM configuration then you're going to get workspace errors. The BDI will still be able to work without the workspace RAM, it's just slower.
Hope that helps, Chris Fester

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 :
#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? Robert
