When trying to attach to M4 upon Linux boot (autoboot=1), it fails to bind resources:Remoteproc driver attempts to probe m4 resources, but all are waiting for pinctrl@50002000 which does not appear before remoteproc probe has timed out. I can see in ...

Hi,Migrating to STs ecosystem v.5.1.0 from v.3 right now and having an issue with M4 where remoteproc is unable to attach to running M4 and consequently fails. From what I can see in the logs there is a timeout while waiting for the resources, in fac...

Hi,I am using internal temp sensor DTS and have critical trip point of 120 C configured. I wonder how interrupt work in this case? Where and how should it be handled? Are trip points the only cases when interrupt from DTS happens?

Hello,I have a interrupt conflict between two peripherals on pins PK7 and PI7. I am aware that these two end up on same EXTI7 interrupt mux, hence conflict in interrupt occurs. I am wondering if there is a way to separate these interrupts on differen...

I am trying to configure SPI5 on STM32MP151C where MPU is a master and ESP32C6 is a slave. The clock used in the device tree is HSI 64MHz. SPI driver is running with 2MHz configured and divisor in the SPI_CFG1 register is correctly set to 32. In the ...

Thanks for the answer! Adjusting oscilloscope sampling rate did the trick - it was way to low for 2MHz frequency

I could see the clock using oscilloscope, it's frequency however is 20 times lower than configured. I start the driver with 1MHz configured and what I get out is 50KHz. SPI5 is set up to use HSE clock of 24MHz. Trying to understand if there's any div...

Hi Erwan,We had some progress on this and currently the driver kernel module is loaded, but the clock looks still disabledRight now SPI5 it is configured to use CLK_SPI45_HSE which is 24 MHz, but enable count in clock tree is still 0:SPI device confi...

Thanks. I also suspect it is a driver issue. I tried to plug in a driver from ESP32 (esp-hosted-ng), but I am not sure how to do it properly right now. It is "baked" together with image, but I am just not sure what to write in "compatible" field
