Hi there I'm learning how to remote debug u-boot through serial port. In menuconfig general setup, I selected "enable debug information for tools". It adds -g in gcc flag. After built is over, I got u-boot, u-boot.sym, u-boot.map and a few other files. When I run objdump -trS u-boot, it does show the source code and the symbols.
However in gdb, when I tried to load the ELF executable file, I got this error (gdb) file u-boot Reading symbols from u-boot...BFD: /root/work/cid_iafw_opensource-coreboot/payloads/external/U-Boot/u-boot/u-boot: attempt to load strings from a non-string section (number 0) BFD: /root/work/cid_iafw_opensource-coreboot/payloads/external/U-Boot/u-boot/u-boot: attempt to load strings from a non-string section (number 0)
Anything I missed and caused this issue? Also I wonder if I want to enable remote debugging of u-boot through serial port, what shall I do in the configuration? I didn't see such option in menuconfig. Is it enabled by default or shall I enable CONFIG_CMD_KGDB in my board config file ?
Thanks, Chi
