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:

Adding UART4 to amazon freetros project on STM32L475E

I am looking for how to add UART4 to this aws_demo project I found from here: https://github.com/aws/amazon-freertos/tree/master/demosQuestion

I need an interrupt to trigger when receive buffer is full so i can move date into an array.

I tried using the cube generator to generate code for uart4 and the copy into aws demo project in same places.

Seen code in main.c and st32l4xx_it.c that i copied over but here are the errors attached screen shot.
