SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   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 get more information from the ac6-tools website and download two short videos (registration required) highlighting:

Nucleo-L152RE - I/O register incorrectly mapped

Hi ST world,

I have an issue debugging on Nucleo-L152RE and openstm32.

It seems that “I/O register” window is incorrectly configured:

USART1: address: 0x40013800
which is OK but:

USART1->SR: address: 0x40022800: strange isn’t it ?
... same offset for the other UART1 related registers

My project is configured for Nucleo-L152RE and I’m using last version of framework/compiler.
How is this mapping defined ?
Maybe I have an issue in my configuration setting I/O register addresses (include file retrieved from the HAL ??)

Any other ideas ?
Thanks regards,
Sylvain

Hello Sylvain,

Indeed there seems to be an issue with the CMSIS register description file : address offset of USART SR is 0xF000 which cannot be correct.

I will check with the value with the people in charge of this description file and keep you informed.

Kind regards,

Pascale


Hello Sylvain,

The issue has been fixed.

Best Regards,

Pascale
