I have a ported u-boot base on 8548CDS for my 8548 board. The U-Boot version is 2008.10. the u-boot boot up was successful. I am trying to use BDI2000 do some debuging.
the BDI2000 config file is as below. with this config file, I can flash program and bring up my board. However, when I try to set a hardware break point, the u-boot code halt before it reach the break point.
Make sure that the BDI is not doing any initialization of the board that could be confusing u-boot.
;================= setup for flash programming =============== ; Move CCSRBAR to 0xe0000000 ; WM32 0xff700000 0x000e0000 ;CCSRBAR to 0xe0000000
This one in particular will kill anything that was expecting CCSRBAR to be at the hardware reset value.
I guess this is because that CFG_CCSRBAR_DEFAULT is not accessable. but the u-boot code did the set_tlb() already. Do i need to set tlb in the BDI2000 [INIT] section? what is the relationship between the u-boot and BDI2000 init procedure?
This has nothing to do with TLBs; it is the physical address of CCSR that was changed.
