For MONITOR_BASE=TEXT_ADDR=0xFFF00000 you need CFG_FLASH_BASE=0xFF800000. Check BDI initialisations and set the HRCW to
Actually I think that using "CFG_FLASH_BASE=0xFF800000" or similar for a high-boot configuration is not optimal, as it does not adjust automatically for varying flash sizes.
Usually I use something like
#define CFG_FLASH_BASE (0-flash_info[0].size)
or even
#define CFG_FLASH_BASE (0-flash_info[0].size-flash_info[1].size)
in such cases.
Just an idea....
