Oh. I hope this question is not off topic in this mailing list:u-boot.
I'm new to BDI2000, and after reading a manual that came with the tool, I tried to debug ppcboot using bdi2000 and gdb. The problem is I just can't set the breakpoint whether be it software or hardware breakpoint; For example, when I set the break point at "boot_cold" and type "continue", the program just runs without ever stopping at the breakpoint where it's supposed to stop!
Here's what I did: a. turn on bdi2000. b. connect to bdi2000 in gdb session. c. set the breakpoint d. type "continue"
========== 90 li r21, BOOTFLAG_COLD /* Normal Power-On: Boot from FLASH */ (gdb) l 85 .ascii CONFIG_IDENT_STRING, "\0" 86 87 . = EXC_OFF_SYS_RESET 88 .globl _start 89 _start: 90 li r21, BOOTFLAG_COLD /* Normal Power-On: Boot from FLASH */ 91 b boot_cold 92 sync 93 94 . = EXC_OFF_SYS_RESET + 0x10 (gdb) b boot_cold Breakpoint 1 at 0xfff02000: file /home/users/qpark/hobby/ppcboot-1.1.6/cpu/74xx_7xx/start.S, line 253. (gdb) cont Continuing. (continues for good...) ==========
What am I probably doing wrong? FYI, I tried to remove H/W breakpoint before I entered "go"
Any help would be greatly appreciated!!
