CFG_MONITOR_BASE at 0xfff80000 makes me think that the U-Boot image has a size of 512k. But CFG_MONITOR_LEN is 256k. Which one is correct? I would think that 256k should be enough for this image.
That's a valid point. Actually u-boot.bin is 512kB in length, but only because there's a reset vector at 0xFFFFFFFC. u-boot itself is really only 256kB in size.
So now I wonder - what's correct? If CFG_MONITOR_LEN applies to RAM, which it seems to since it only really affects TOTAL_MALLOC_LEN, then 256kB is correct and no change is required.
I would change the image size to 256k to safe some space in FLASH. For this you have to change TEXT_BASE (in config.mk in your board directory) to 0xfffc0000. And CFG_MONITOR_BASE too. Or even better:
#define CFG_MONITOR_BASE (TEXT_BASE)
Starting here
+#define CFG_FLASH_WORD_SIZE unsigned short +#define CFG_FLASH_ADDR0 0x0555 +#define CFG_FLASH_ADDR1 0x02aa +#define FLASH_BASE0_PRELIM CFG_FLASH_BASE /* FLASH bank #0 */
till here. These defines are most likely not needed for the CFI driver. Please remove them.
OK, I'll look into it.
Thanks.
