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.

System Workbench for STM32

Compiler (arm-none-eabi-gcc) just don't wanna make interrupt vectors (CMSIS, StdPeriphLib)

Guys, the reason blue pill didn’t want to work after reset was wrong placement of BOOT jumpers - they both should’ve be set zero. But my question still remains - where is damn interrupt vector? xDDD. How do i see it? So far everything seems to work fine, so interrupt vector must be on it own right place, but it absents in object file, i have doubts
