| 09:32.17 | vmaster | xela: hey... now I am ;) |
| 09:35.09 | xela | :-) |
| 09:35.34 | xela | I tried to debug with gdb |
| 09:42.45 | xela | When I try to set a breakpoint gdb seems to assume sw breakpoints |
| 09:43.41 | xela | Info: arm7_9_common.c:275 arm7_9_add_breakpoint(): sw breakpoint requested, but software breakpoints not enabled |
| 09:43.42 | xela | Info: breakpoints.c:73 breakpoint_add(): can't add software breakpoint, resource not available |
| 09:45.49 | vmaster | "monitor arm7_9 force_hw_bkpts enable" |
| 09:46.07 | vmaster | this causes the OpenOCD to replace any breakpoint requested with a HW breakpoint |
| 09:46.45 | vmaster | if you want to use SW bkpts later on you have to explicitly enable them: "monitor arm7_9 sw_bkpts enable", as SW bktps take up one of only two HW comparators |
| 09:47.00 | xela | ah i see |
| 10:03.27 | xela | works like a charm... |
| 10:10.49 | xela | Often, i get the gdb error: |
| 10:10.50 | xela | (gdb) Cannot access memory at address 0xffffffff |
| 10:10.56 | xela | while stepping |
| 10:12.41 | vmaster | that happens when GDB tries to unwind the stack when there are no more stack frames |
| 10:12.50 | xela | ah isee |
