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 (registration required) various documents highlighting:

STM8S103F3P6 development board help

I got an STM8S103F3P6 development board, I’m attempting to execute a typical linking-led application, but I’m not sure what I’m doing incorrectly. A LED was connected to PIN D3; the following is my code:

1. include

delay_ ms (uint16. _t ms) ;
delay_ _ms(uint16 _t ms) {
(ms- -) {
uint16_ t i;
(i = 0:i< ms; i++){
nop () ;

//PD3 as Output
GPI0D- >CR1 |=0x03:
//PD3 as Push Pull
