Hi, I have done 'reset halt' and 'arm7_9 sw_bkpts enable' from openocd for debug board v3 and FR. I have flashed the built u-boot to NAND. Proceeding to use gdb:
/usr/local/openmoko/arm/bin/arm-angstrom-linux-gnueabi-gdb (gdb) file /path/to/u-boot Reading symbols from /path/to/u-boot...done. (gdb) target remote localhost:3333 Remote debugging using localhost:3333 0x00000000 in ?? () (gdb) load Loading section .text, size 0x2658c lma 0x33f80000 Loading section .rodata, size 0xf60 lma 0x33fa658c Loading section .rodata.str1.4, size 0x9240 lma 0x33fa74ec Loading section .data, size 0x4070 lma 0x33fb072c Loading section .u_boot_cmd, size 0x6d8 lma 0x33fb479c Start address 0x33f80000, load size 216692 Transfer rate: 217099 bits/sec, 12746 bytes/write. At this point, I am able to set breakpoints: (gdb) b cpu_init Breakpoint 1 at 0x33f81fa4: file cpu.c, line 99. Doing 'info registers' shows pc at 0x33f80000: (gdb) info registers ... pc 0x33f80000 0x33f80000 <_start> fps 0x0 0 cpsr 0x200000d3 536871123 But, when I do "stepi", I get: Unable to set 32 bit software breakpoint at address 33f80000 Unable to set 32 bit software breakpoint at address 33f810c4 Unable to set 32 bit software breakpoint at address 33a3abb0 target state: halted target halted in ARM state due to breakpoint, current mode: Supervisor cpsr: 0x200000d3 pc: 0x00000000 MMU: disabled, D-Cache: disabled, I-Cache: disabled The u-boot offset address that is built starts from 0x33f80000, which is in nCS6 - RAM. How can I debug the u-boot on the NAND? My libftdi1 is 0.13-2 on Debian. Appreciate any inputs, Thanks!
