Hi again, hope you are having a good day. We are trying to record audio with the integrated audio codec with a python script, but it starts with an abrupt peak every time like the image below.We have tried to configure the alsamixer and nothing chang...
I am using 2 virtual UARTs as described in STM32MP1Cube Applications/OpenAMP/OpenAMP_TTY_echo example and watchdog for M4 core.Problem occurs when I using select or poll syscall to read from the device. Kernel panic occurs with following on dmesg log...
Hello!I have an issue on a custom board with STM32MP153CAB and KSZ8081RNB.TF-A, FIP and kernel were built in Developer package. Linux distribution was built as startard configuration st-image-core in Distribution package.Clocks and device trees are c...
I'm using STM32MP157A-DK1 development board, in this we are using it for audio application,I'm porting stlinux in the board by yocto BSP.I wanted to know the codec(CS42l51) available on the board at what default clock it is operating and is it using ...
The gcc variant in STM32MPU Embedded Software distribution components is 'arm-ostl-linux-gnueabi-gcc'. Then what's the difference between 'arm-ostl-linux-gnueabi-gcc' and 'arm-none-linux-gnueabi-gcc'?Thanks.
I am building softwares for my cutom board based on STM32MP1 using OpenSTLinux. I get lot of kernel-module-* packages installed in the rootfs. I found they are build because fragment-03-systemd.config is added to kernel config if systemd is used.Can ...
i‘m not using qt or other 3rd gui framweork, no weston, no x, just direct use drm api，i need switch off lcd after some time is not operated，i google it a while，It looks i need a complete desktop environment to do that，so i want know is any way to do ...
Hi All,i am getting kernel soc sgtl5000.c errorsgtl5000 0-000a: Error reading chip id -6any idea where am i missing , let me know if you need any further inputs&i2c1 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&i2c1__pins_a>; pinctrl-1 =...
I have set :hostname_pn-base-files = "new_host_name"in my conf file.This seems changing /etc/hostname in base-files image. However, there is log message telling:"[ 7.249795] systemd[1]: Set hostname to <stm32mp1-disco>."Also, /etc/hosname contents ...
Hi ST!I am working with Rust on your STM32MP157. While we have this working already, this is cumbersome as we have to figure all register addresses and layouts manually. Normally, in Rust, we parse the SVD file corresponding to a chip and go from the...
