    • What means the Msp in HAL_MspInit ?

    Posted by BenoitHanridge on 2016-03-04 21:16

    Hi All,

    When Googling 'STM32 HAL What is MSP' and absolutely no relevant answer comes as result then a system of developing has become seriously archaïc.

    Anybody knows what MSP exactly stands for? It's neither explained in none of the repository files.

    Greets,
    Ben

    I wondered the same thing before finding a definition of "MCU Support Package".

    Unfortunately, after stumbling across that definition I just picked myself up and carried on and now I have no idea where I found it...

    ST document UM1718 section 5.1

    Took me a while to find as well.

    Cheers

    This comment generated by the CubeMX at the start of main()
    defines MSP.
    /* STM32F4xx HAL library initialization:
    - Configure the Flash prefetch, instruction and Data caches
    - Configure the Systick to generate an interrupt each 1 msec
    - Set NVIC Group Priority to 4
    - Global MSP (MCU Support Package) initialization
    */

    Hmmmmm,

    This comment does not appear in any file I create using STM32CubeMX V4.13.0

    Me too. Well yeah... I guess I'm not the only one that was obsessively hung up in what turned out to be a STUPID LOOP on finding that #@!!@#$!~@!....."thing"

    Deedle dum.... "TSCH"

    Wahhh waahhh

    ❗ In UM1718 I see it in section 6.1, not 5.1.

    MSPs are user callback functions to perform system level initializations such as (Clock, GPIOs, DMA, interrupts).

    The peripheral initialization is done through HAL_PPP_Init() while the hardware resources
    initialization used by a peripheral (PPP) is performed during this initialization by calling
    MSP callback function HAL_PPP_MspInit().
    The MspInit callback performs the low-level initialization related to the different additional
    hardware resources: RCC, GPIO, NVIC and DMA.
