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 se...

Above are all good answers.In a short summary, from a command shell, you --Install the 'repo' tool, which is a python tool for managing clusters of sub repositories as a single group.Run 'repo init ....' command to clone the openSTM32 yocto repositor...

Excellent response!I will definitely check it out.Any ideas on schedule for 1.9.0?

I realize this is an old question, but want to answer it for other searches since I am involved in a powerSTEP01 ihm03a1 project.Absolutely, YES, you must use heat sinks to get the specified max current rating. Any power transistor or FET used for s...

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 ...

@Bumsik Kim -- what is the status on your port? I am attempting to get the powerSTEP01 IHM03A1 running on the DK2 (stm32mp1), and am very interested in being able to open /dev/ttyRPMSGx for bidirectional communication with the M4. I pulled the lat...
