arm-none-eabi-gdb is not compatible with Emacs built in gdb?

[czqhurricane]

Thanks your effort to share this package.

When I am exploring stm32-emacs, encounter a problem.

Try: M-x stm32-start-gdb-elf then select cfg file and elf file. "stm32-gdb-server" starts successfully,
then Emacs ask "Enable querying debuginfod servers for this session? (y or n) ",
then I enter "y" and hit "Enter" to comfirm.
But "gud-target extended-remote localhost:3333" thow a error:

Debugger entered--Lisp error: (wrong-type-argument gdb-handler nil)

So I decide to do a litter dig into this.

I try to run

  gdb("arm-none-eabi-gdb -iex \"target extended-remote localhost:3333\" -i=mi  /Users/c/Downloads/STM32Project/STM32F103ZET6__CubeMX__/FreeRTOS/Demo8-1_Notify_ADC/./build/Demo8-1_Notify_ADC.elf")

this command string:

arm-none-eabi-gdb -iex "target extended-remote localhost:3333" -i=mi  /Users/c/Downloads/STM32Project/STM32F103ZET6__CubeMX__/FreeRTOS/Demo8-1_Notify_ADC/./build/Demo8-1_Notify_ADC.elf

in Emacs built in gdb manually.

It throws error too.

Then I try the same command string in gub-gdb, It runs successfully.

Here is my Emacs information:

Finally, if I change from gdb to gub-gdb in this line:

stm32-emacs/stm32.el

Line 151 in e3f1e17

(gdb (s-concat stm32-gdb-command " " (concat root file)))))))))

I can run command stm32-start-gdb-elf to start gdb server and debugger succesfully.

So what causes the difference?
