stm32mp157f, I need to use uart5 to drive an rs485 but the hardware supplied DE pin is already in use. So I need to configure a different GPIO to use. If the device tree binding rts-gpios is supported, then the task is simplified. We can modify the...

Processor stm32mp157f, our board design similar to dk2.In my STM32CubeMX generated device tree (dunfell) I have added the following:/* USER CODE BEGIN root */soc {vrefbuf@50025000 {status = "disabled";};};/* USER CODE END root */I have my vref pin co...

As Mickledore is no longer supported (by yocto) when can we expect an updated yocto release from ST for the stm32mp1 series?

I want to regenerate all my files, originally for the stm32mp157cac for the stm32mp157fac, in particular the devtree files. I suspect that the files are the same but I need verification. If they are not the same, how do I go about the update (witho...

I am trying to set up 3 ADC. I set PA4 to ADC1_INP18, PA5 to ADC2_INP19 and PF11 to ADC1_INP2. Will this be something that works? I am monitoring 3 lines (none NEED to be fast).I'm not clear on how to set this up. I am multiplexing several inputs...

I don't see where this addresses my question, perhaps I don't understand? I am aware that I can do this with some coding in kernel but my understanding was that most of what I would need to do was already done if you include rts-gpios in the devtree...

I think I found my answer. In &adc{I added vref-supply = <&vdda>;And that seems to have fixed it.

We have this issue with both builds, basic and trusted. We will be using trusted configuration in our product, support for this along with the crypto engine was a deciding factor going with this SOC (we provide security devices for the military).Stev...

For some reason my answer didn't come through. I include it here.What is the problem that you encounter with the USB port 1? Do you have an error?The port doesn't reset.The port related to OTG is the port 2:https://wiki.st.com/stm32mpu/wiki/USBPHYC_...

Re: We are building a board based on ST32mp157c and have problems enabling USB port 1. We did not include the ECMF02-2AMX6 choke. Could this be the problem?
