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.

I’m trying to reprogram a custom STM32F407ZGT6 board however the 4pin programming port connectors are Vdd PE0 PE2 GND.
I looked in the datasheet but didn’t find any programming functions related to PE0 PE2. Could it be a custom bootloader that uses these pins?
