Message-ID: <dhve61$2hd$1@sea.gmane.org> (raw)
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
