I suspect there is a problem with ARM11 debugging for version v0.4.0-rc1-128-g0c3a4b4. It seems I cannot insert breakpoints:
Here I single step, to prove that I can reach the address I want to set the breakpoint at: (gdb) moni reset init JTAG tap: imx31.etb tap/device found: 0x2b900f0f (mfg: 0x787, part: 0xb900, ver: 0x2) JTAG tap: imx31.cpu tap/device found: 0x07b3601d (mfg: 0x00e, part: 0x7b36, ver: 0x0) TAP imx31.whatchacallit does not have IDCODE JTAG tap: imx31.smda tap/device found: 0x2190101d (mfg: 0x00e, part: 0x1901, ver: 0x2) found ARM1136 imx31.cpu: ran after reset and before halt ... target state: halted target halted in ARM state due to debug-request, current mode: Supervisor cpsr: 0x200001d3 pc: 0x0040560c Target Setup: initialize DRAM controller and peripherals set p15 0x0001, 0x00050078 configuring CP15 for enabling the peripheral bus set p15 0x042f, 0x40000015 (gdb) load Loading section .rom_vectors, size 0x40 lma 0x87f00000 Loading section .text, size 0x3cc98 lma 0x87f00040 Loading section .rodata, size 0x91a4 lma 0x87f3ccd8 Loading section .exidx, size 0x10 lma 0x87f45e7c Loading section .data, size 0xd8c lma 0x87f45e8c Start address 0x87f000e0, load size 289816 Transfer rate: 46 KB/sec, 13173 bytes/write.
