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
Shabbirali
