Downloading and Runnig U-boot from RAM using CodeWarrior

[shabbirali]

Hi,

I am using MPC8548CDS and CodeWarrior IDE version 5.7.

Would someone please help what are the changes required in U-boot code or MPC8548CDS_init.cfg to make it load in RAM and run it from RAM using Codewarrior.

I have Connected Codewarrior to MPC8548CDS system using USPTAP and using Load/Save memory option i loaded u-boot at location 0x100000. When i set PC  at 0x001FFFFC as it is a reset vector it gets lost some where after executing arond 30 instructions

I have made follwoing changes

1) enabled CFG_RAMBOOT in MPC8548CDS.h.

2) TEXT_BASE = 0x00100000 in config.mk

3) replaced 0xFFFFxxxx with ox001Fxxxx.

When i use this u-boot.bin on top of uboot then it works but i want it working through codewarrior.

Please suggest changes in uboot.

Regards
