Hi,

I try put a brakpoint in function cpu_init_f, but is not working

my config in BDI is:

8315-uhet>reset
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed
- Bypass check: 0x00000001 => 0x00000001
- JTAG exists check passed
- IDCODE is 0x268B401D
- BDI overrides HRCW (0x84600C00 0x42050000)
- BDI removes HRESET
- PVR is 0x80850020
- SVR is 0x80B40012
- BDI sets breakpoint at 0xFFF00100
- BDI resumes program execution
- Waiting for target stop passed
- TARGET: Target PVR is 0x80850020
- TARGET: resetting target passed

If I try TI command:

8315-uhet>ti
    Target CPU        : MPC83xx (e300c3)
    Target state      : debug mode
    Debug entry cause : COP halt

    Current MSR       : 0x00000000
    Current LR        : 0x00000000
# Step timeout detected

if I try read the entry point:

8315-uhet>mdh 0xfff00100
# SAP: read access failed

using sap command:

8315-uhet>mdh 0xfff00100
fff00100 : 0000 0000 0000 0000 0000 0000 0000 0000  ................

There are nothing in flash?
But when I take out the BDI, I start uboot, I can read de memory:

ATMX> md.b 0xfff00100
fff00100: 78 5e 52 c8 4f 53 28 49 4c 2f 56 c8 cc 53 c8 48    x^R.OS(IL/V..S.H
fff00110: 4d 4c 49 2d 2a d6 51 e0 52 20 00 ac 81 ca 4b 52    MLI-*.Q.R ....KR
fff00120: 8b f2 12 4b 32 f3 f3 12 73 14 92 33 12 8b 12 93    ...K2...s..3....

Anybody can help me?
