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

MSP = MCU Specific Package

Source: Acronyms and definitions of “UM1725 User Manual Description of STM32F4xx HAL drivers” (http://www.st.com/content/ccc/resource/technical/document/user_manual/2f/71/ba/b8/75/54/47/cf/DM00105879.pdf/files/DM00105879.pdf/jcr:content/translations/en.DM00105879.pdf)

exclaim 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.
