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:

System Workbench for STM32

missing 'Ac6 STM32 Debugging' Debug configuration in Debug perspective

Ciao Roberto,
I’ve did as You said, see attached image,
still I cannot have printf in ‘Console’ of System Workbench for STM32 via ITM.

I defined __io_putchar function, overwriting weak definition, like this:

FENCEif !defined ( BSP_LCD_USE )
int __io_putchar (const char ch)
uint32_t ch_ = (uint32_t)ch;

return (int) ITM_SendChar ( ch_ );

since my STM32F746-DISCOVERY board has an LCD, with LCD I don’t need it.

What can be done next to have debug printf on System Workbench for STM32 Console ?
