Issues with running FatFs_eMMC_Standalone - STM32CubeIDE

[Sid Price]

I just received an STM32L4P5 Discovery board to evaluate eMMC for the STM32L4. In the firmware package for the STM32L4 there is an example project, "FatFs_eMMC_Standalone". I have built the example, however, when I try to run it the application halts in "initialize_monitor_handles". (SIGTRAP Trace/Breakpoint Trap)

Seems there is perhaps an option missing in the project, can anyone help me to resolve this please.

Hello @Community member​ ,

Which Firmware package version are you using ?

Have you proceeded like described in the readme.txt file?

Have you made any changes to the example provided in the Cube package?

Hi @Imen DAHMEN​ , I have changed nothing in the project, just opened it in STM32CubeIDe, built it, and tried to run it. I think CubeIDE updated the firmware package to STM32Cube_FW_L4_V1.16.0.

Hi @Community member​ ,

You are right, I reproduced this issue with FatFs_eMMC_Standalone example, using STM32Cube_FW_L4_V1.16.0 and STM32CubeIDE v1.5.0.

This example doesn't work on STM32CubeIDE, as there is a debugging issue on the semihosting configuration while calling the initialise_monitor_handles() function.

As workaround, I updated the Debug configuration in STM32CubeIDE as follow:

1- Use and configure ST-LINK (OpenOCD).

2- Add the command "monitor arm semihosting enable" into startup Initialization commands .

I hope this workaround is helpful for you.

Thanks for pointing out this issue, I have passed it along to our development team for fix.

@Imen DAHMEN​ Thanks you, this was the work-around I got from a case I opened and it is a great work-around.

I look forward to an updated CubeIDE so that I may continue using GDB server.

@Community member​ , Glad to know that the issue is solved for you :smiling_face_with_smiling_eyes:

After an internal cross-check (with the STM32CubeIDE team), actually, there is no plan to integrate this feature.
