STM32MP1 support available in SW4STM32

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4; you can download a short video showcasing this on the ac6-tools website (registration required).

System Workbench for STM32


Connect to custom board STM32L053 - STLINK-V2 - SWD

Hi Kevin,

thanks for quick reply: I made what you suggested without more results but
here is the console log which is interresting:

Something wrong in my connection ? That’s unlikely as it is ok with stlink-32 utility.
Do you have an idea how to halt the µc ?

Thanks and regards,
Sylvain

Workaround: increase “set remotetimeout” in GDB

Any pointers on why this happens and were we “set remotetimeout” in GDB with System Workbench?

I found the setting, just add the variable to the GDB tab on he project

Could you describe in detail where you entered this variable? I can not dismantle this warning.

Edit

when I use command in Debugger Console: “show remotetimeout”
I received answer: “Timeout limit to wait for target to respond is 2.”

Why in the message:
Warn : keep_alive() was not invoked in the 1000ms timelimit. GDB alive packet not sent! (4517). Workaround: increase “set remotetimeout” in GDB
is the information about 1000ms?
