Before relocation with "symbol-file" command:.If you connect GDB on running target, you can load the debug symbols: With U-Boot relocation, symbols are more difficult to load. start execution with the "continue" command.#Load U-Boot symbol, #Load SPL symbol, #Load SPL code and debug load the symbols of the binary to be debugged with commands available in next chapter:.reset with attach the target with the gdb "monitor reset halt" command:Įxecution is stopped in ROM code or at the beginning of FSBL execution.(u-boot and u-boot-spl available in the build directory) get the elf files for U-Boot and/or SPL.Or for manual GDB connection, you need to: With OpenSTLinux, you can directly use GDB script Setup.gdb: This function needs to be adapted for your board. adapt the function board_debug_uart_init(): that configures the required resources (pad, clock) before initialization by the U-Boot driver.add in defconfig of U-Boot configuration.If U-Boot fails before the console configuration (in the first stage of U-Boot execution), trace is not available. edit the Makefile and add DEBUG=1 option on used CFLAGS with:.edit your defconfig file and add the option:.If you want to enable the DEBUG traces for all the source code, you have to : define DEBUG before any include in the.

See page How to configure U-Boot for your board for configuration details.īy default, the macros used by U-Boot (debug(), pr_debug().) do not print any trace to activate the debug traces on a specific file, you need to enable the DEBUG compilation flag and change the LOGLEVEL for the file: Trace and error are available on the U-Boot console which use stdout-path defined in the chosen node of the Linux kernel device tree as described in the Linux kernel binding.
