I'm currently using the dual-core STM32H745, and am trying to utilize DMA's on both cores to R/W to/from shared memory. DMA's are only successful on the M4 cores, and always yield a DMA Transfer Error. I haven't done anything to modify the initializa...

Hello,Looking over the STSpin implementation of the Clarke Park transforms and SVM has raised some questions about the derivation of the transform. Typically the the Clarke Transform takes the form of:퐼훼=퐼푎퐼훽=1√3(퐼푎+2퐼푏STSpin's implementation effecti...

Hi all,I'm attempting to run the simplest example code provided for the STM32H745XI dual core (M7 and M4 cores). I've configured my cube debugger as explained in the link below, and I'm having no success debugging or even starting the second core (M4...

Hello,We are using the STM32H745 dual core series, and have an image size that is nearing the single flash banks limit of 1MB. We won't be using the swap bank feature at any point. Will there be issues if the image overlaps the second bank?

Thanks @Bouraoui Chemli , the MDMA works fine on the M7. A related question would be whether the performance of the MDMA and DMA for MEMTOMEM writes is identical. The assumption being that if two DMA's access the same buffer it will prevent a race c...

I did allocate space in D2SRAM in the linker and assign a buffer the memory attribute, but it was still failing. Could there be some conflict caused between the two cores both initializing the same DMA? Alternatively, I haven't tried using the MDMA p...

Hello Laurent,We're not having issues with the implementation per se, more so just trying to understand it so we can spot any issues. I found this PDF over the weekend which seems to deeply describe the derivation of both the SVM and FOC in the STSpi...

So it turns out it was a hardware issue... I flashed the same firmware on a newer PCB revision and it works without a hitch. I suspect the regulators were damaged on the other revision which caused issues for both cores to run simultaneously consider...

Perhaps your debug configuration would be useful as well
