Can anyone please give me advice on the following: U-boot was burnt at 0xfff00000 (.TEXT) and starts successfully whenever I disconnect BDI2000 and power cycle our MPC8272ADS. Without BDI it starts without any problems. But when I try to debug using BDI board keeps restarting:

8272>reset - TARGET: processing user reset request - BDI asserts HRESET ... 8272>info Target CPU : MPC8280/8220/5200 (Zeppo) Target state : debug mode Debug entry cause : instruction address breakpoint Current PC : 0xfff00100 Current CR : 0x00000000 Current MSR : 0x00001002 Current LR : 0x00000000 8272>go *** TARGET: reset detected, restarting target - BDI asserts HRESET ...

Reset entry point is at offset 0x100 so in fact 'go' does "go 0xfff00100" from my understanding, but why is it keep resetting? No serial output produced.

The map file .text 0xfff00000 0x2ec14 cpu/mpc8260/start.o(.text) .text 0xfff00000 0x3560 cpu/mpc8260/start.o 0xfff001b0 _start_of_vectors 0xfff03178 init_8260_core 0xfff032ac dcache_enable 0xfff03314 relocate_code 0xfff00000 _hrcw_table 0xfff0324c icache_enable ...

What do I miss?

Thank you,

Dimitry
