Being relatively new to Yocto, I struggle a bit with some issues.I intend to use ADC channels in my (user space) applications, but the channel names seem confusing.Listing /sys/bus/iio on a live system, I can see two ADC devices, device_0 and device_...

I having some difficulties figuring out details about the ADC usage under Linux, in particular on the MP135F-DK.I located the io driver sources, and the drive itself seems to work:Checking the board user manual, the GPIO pins PC2 and PC3 are routed o...

While I got some experience with Cortex M devices - including several STM32 families - and Linux as host OS, I'm pretty new to asymmetrical dual-core systems like the STM32MP1 devices.What sets them apart is the tight integration of both cores, and t...

I don't know the H5, to put this upfront. Although I think this is not especially significant.Trying to wrap my head around this issue and code ...> In the last one, I put the code 'DATA_TransferCompleteRx();' in the comment line of the DMA interrupt...

> You're going to need to give a lot more detail for anyone to be able to help!Correct."Doesn't work anymore" contains nothing to really work with.I would suspect a core lock-up, due to a faulty exception handler.
