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.

    The _estack values above should be:

    _estack = 0x20020000; /* one byte after last RAM address*/

    and

    _estack = 0x10010000; /* one byte after end of CCMRAM */

    to be 8-byte aligned or you will see errors printing longs and floats

      Hi

      Thanks for the heads-up; the linker scripts had been updated a while ago, but this documentation page was missed...

    Hi, i think the line
    char in_ccram_buffer1024 attribute((section(“ccmram”)));
    is missing a dot in front of ccram, should be
    char in_ccram_buffer1024 attribute((section(“.ccmram”)));

    Are you sure this makes sense? I’m just learning this and I’m trying to figure this out, but comparing to code from STM32Cube, which seems reasonable, it should be
    _siccmram = LOADADDR(.ccmidata)

    and
    ldr r3, =_siccmram
    (although it wouldn’t be called ‘ram’ now, as it would address of the section in flash)
