Adding .elf files to debug context when using multiple binaries?

gearhead1107 — Wed, 11 Oct 2017 23:19:24 GMT

I'm working on a "mini" bootloader which pulls in a bootloader .bin from another project in S32DS. After making the jump to the application, I naturally don't have any source code to step through since it's not part of the project.

I poked around at a few guides, namely this one (“No source available”, or how to Debug Multiple Binaries with GDB and Eclipse | MCU on Eclipse ) and in Debug Configurations-> Startup -> GDB run commands I added the following (where 0x10410 is the .text space according to the map file)
add-symbol-file "[file path]Bootloader_A00.elf" 0x10410

In my debugger console I see the following;

add-symbol-file "[file path]Bootloader_A00.elf" 0x10410
add symbol table from file "[file path]Bootloader_A00.elf" at
.text_addr = 0x10410
(y or n) [answered Y; input not from terminal]
Reading symbols from [file path]Bootloader_A00.elf...done.

however after the jump to Bootloader, I still get the "no source available for "_binary_C__Users_[myname]_workspaceS32DS_ARM... at [location in bootloader]" "

I've made sure I'm building in debug, but still can't see my code from the bootloader... any commands that I'm missing here?

Hello Andrew,

Thanks for your question. I've tested this and I've basically reached the same point.

I'd suggest you to rather switch the symbol files via "Debugger Console" / GDB client console as a workaround.

e.g. to load bootloader symbols type the command below into GDB client console:

symbol-file <Path_to_your_BL_elf>\S32K144_bootloader.elf -readnow

* refresh the IDE (menu File ->

and now the bootloader sources/symbols are available:

repeat the steps for the application symbol-file:

In the meantime I'll check with our debugger team what might be wrong with add-symbol-file.

Regards,

Stan

Thanks, Stan - this definitely works as a temporary solution.

One important note for anyone following along is that you have to refresh the debug context - not the file explorer context.
