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:

Very strange .bss RAM overflow



You do not give really enough information to get sensible help; what does the HighDensSequentialRead does with the AdrGradScale value and, BTW, what is this value? What is the usefulness of the IR_Sensor_Read function (from a C point of view): it does not return anything and computes a value (gradScale) that is not used (meaning the compiler may not even compute it).

In the modified code, how did you define globally gradScale?
