Hello,
I am confused about the followin fields in HRCW, MPC8272
CIP -
0 MSR[IP]=1 (default), Exceptions are vectored to the physical address 0xfffn_nnnn 1 MSR[IP]=0, Exceptions are vectored to the physical address 0x000n_nnnn
BMS -
Boot memory space. Defines the initial value for BR0[BA]. There are two possible bootmemory regions, HIMEM and LOMEM 0 0xFE00_0000 -- 0xFFFF_FFFF 1 0x0000_0000 -- 0x1FFF_FFFF
My question:
1) Given BMS = 0 Does this mean, the FLASH(on CS0) are given the base address as 0xFE00_0000?
2) Given CIP = 0 Does this meman, the vector should be placed at 0xFFFn_nnnn?
So With BMS=0, and CIP=0, my flash should be bigger than 0xFFFn_nnnn - 0xFE00_00000 >16M, right?
3) 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
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.
Any ideas? Thanks ahead.
Best Regards Raymond
