Hello,
I'm working on the port of u-boot to a custom board based on the MPC8250. I'm using a snapshot from the git repository (last date in the changelog is 7/14/07). I started with the Rattler configuration and have slowly progressed to this point (see output below). I've been stuck here for a couple days and so I thought that I would ask for advice now - hopefully, I am not missing the obvious! I have DEBUG enabled. Boot flash starts at 0xFE000000 (this is also the value of TEXT_BASE) and even though I've set CFG_FLASH_PROTECTION, the CFI code is erasing the flash over the "protected" range - that is, it starts writing at 0xFE000000. Any help would be greatly appreciated!
Anyway, here is a (hopefully) pertinent snippet from my config file:
<snip>
#define CFG_FLASH_PROTECTION 1 /* Real (hardware) sectors protection */ #define CFG_FLASH_BASE 0xFE000000 #define CFG_FLASH_CFI #define CFG_FLASH_CFI_DRIVER #define CFG_MAX_FLASH_BANKS 1 /* max num of flash banks */ #define CFG_MAX_FLASH_SECT 32 /* max num of sects on one chip */ #define CFG_DIRECT_FLASH_TFTP
<snip>
#define CFG_MONITOR_BASE TEXT_BASE #if (CFG_MONITOR_BASE < CFG_FLASH_BASE) #define CFG_RAMBOOT #endif
#define CFG_MONITOR_LEN (256 * 1024) /* Reserve 256 kB for Monitor */
#define CFG_ENV_IS_IN_FLASH
#ifdef CFG_ENV_IS_IN_FLASH #define CFG_ENV_SECT_SIZE 0x10000 #define CFG_ENV_ADDR (CFG_MONITOR_BASE + CFG_MONITOR_LEN) #endif /* CFG_ENV_IS_IN_FLASH */
<snip>

And the output to the console:
