Port SPN3 motor-control examples to DK2?

[karlchansen]

We are considering using a combination of the stm32mp157 and several powerSTEP01 devices in a system with multiple stepper-motors.

The X-NUCLEO-IHM03A1 plugs into the -DK2 just fine, but the SPN3 examples only work on the F0xx, F3xx, F4xx, and L0xx series.

Attempts to port one of the examples to the stm32mp157C-DK2 have not worked.

1. Where can we get information on porting one platform's (e.g. F4xx) "arduino-style" connector to the stm32mp157C-DK2 "arduino-style" connector?
2. Has anyone ported other code from the F0/F3/F4/L0 that uses the "arduino-style" connector onto the connector on the stm32mp157C-DK2?
   1. If so, can the code be shared, or the process documented?

We are approaching the GO/NOGO point of using the stm32mp1 and the powerSTEP01. Time is critical on this.

Hi @karlchansen​ 

Please pay attention that using MP1 in Production mode the resource management is perform on Linux side.

Refer to :

In order to put this aside for a first step and ease the debug, I recommend you to mature the coproc firmware using the engineering boot mode.

Please refer to :

Hope it help,

Olivier

Thanks for the file. I have been firefighting another project and am just now getting back to this one. I'll be taking a look at it this weekend.

I have also been dabbling in arduino on the M4-side of the stm32mp1. It looks like @Bumsik Kim​ has put a lot of work into getting the arduino core working on the stm32mp1, and the company megunolink (https://github.com/Megunolink) has created an arduino library for the powerSTEP01. I am hoping the combination works and will make my tests much simpler.
