"When I attach arm-none-eabi-..." <- > <@0xada3:matrix.org> When I attach arm-none-eabi-gdb to the simple program from Chapter 5.4 of the Discovery book (micro:bit v2 edition), I get several symbol related (I think) warnings and have difficulty doing anything productive with GDB. The even simpler program from Chapter 5.3 seemed to be debuggable. I am running `rustc 1.81.0 (eeb90cda1 2024-09-04)` and `GNU gdb (Arm GNU Toolchain 13.3.Rel1 (Build arm-13.24)) 14.2.90.20240526-git`. The errors I see when I first attach are a bunch of the following: > * `warning: (Internal error: pc 0x100 in read in CU, but not in symtab.)` > > Maybe there is a compatability issue between my build of GDB and the LLVM? I tried upgrading arm-none-eabi-gdb to version 15.1 and it gives the same symbol related errors and has little success in debugging the simple LED lighting program from the Discovery book. I have searched on Google for the errors that I am seeing and no one else seems to be hitting them so it must be something about my setup. It seems like it should be something with my build of GDB or rustc.
