I am trying to connect to audio codecs to give 4 channel of audio on a MP257. Can I connect SAI2.SCKA TO BCK on both , SAI2.FSA to LRCK on both, SAI2.SDA to DIN on the first and SAI2.SDB to DIN on the second.My concern is the clocking, can I common b...
I am getting an error when working through the README.HOW_TO.txt in linux-stm32mp-6.1.82-stm32mp-r2-r0 directory.It seems to work fine until:6.2 Compile External Device tree* Compile and install on a build directory (different of kernel source code d...
If I have grasped USB-C correctly, the BootROM must communicate with the STUSB1600 chip for role negotiation, otherwise it couldn't switch to device mode and thus it wouldn't be possible to use serial boot mode over USB-C. On the DK2, the STUSB1600 i...
I have started working on STM32MP257f board. I have installed open st linux distribution package on my board. Now I want to blink led on my board using my own yacto customized layer. Can anyone please help me with the steps. I have executed simple he...
Hi all, I work on a STM32MP153 device and I used the command echo mem > /sys/power/state to put CPU A7 in Cstop mode, but I still have MCU running. Before to enter suspend mode I have shared some memory buffers with MCU M4 with virtio RPMSG (as re...
Dear Sir, We are using stm32mp135f processor on our custom board. We want to interface flexible external memory controller bus with an external FPGA device. How this can be achieved? Are there any reference or example that you can provide? Is it poss...
Hello,I’m trying to build an EKF (Extended Kalman Filter) application using Bitbake on an STM32MP1 platform, but I’m encountering the following error:Nothing RPROVIDES 'gnss1-ekf' (but /home/futura/STM32MPU_workspace/Distribution-Package/layers/meta-...
Hi everyone,Currently, I am working on STM32MP153 mpu. I am building a Linux image using Yocto.In the image, I want to add a Python package (pyarrow).But when I built the Linux image I got the error, Please see the attached image.
