Does this mean, the FLASH(on CS0) are given the base address as 0xFE00_0000?
Not exactly. 0xFE00_0000 is just one of workable configuration.
- Given CIP = 0
Does this meman, the vector should be placed at 0xFFFn_nnnn?
Correct. This is HIGH BOOT location of 8272.
So With BMS=0, and CIP=0, my flash should be bigger than 0xFFFn_nnnn - 0xFE00_00000 > 16M, right?
No. It just narrows your choose scope. If your FLASH on board hasn't reached 32MByte, you can fit the whole FLASH space in the setting scope as you like.
- Given my flash is 8M byte, 16bit-bus-width, is it
a valid HRCW word for 08_82_32_45 My image got the following configurations MONITOR_BASE=TEXT_ADDR=0xFFF00000 CFG_FLASH_BASE = 0XFE800000
Seems good. But CFG_FLASH_BASE = 0xff800000 is also OK.
I tried many times, with BDI plugged, u-boot works fine.However, without BDI and RSTCN pull-up, looks >
like the image never got run.
Ummm, try to program the same image at 0xff800000 and pull down RSTCN to see what would happen:-)
Best regards,
