This is how I would like to use rs485:&usart3{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&usart3_pins_mx>; pinctrl-1 = <&usart3_sleep_pins_mx>; status = "okay"; uart-has-rtscts; linux,rs485-enabled-at-boot-time; rs485-rts-delay-ns = <80...
Hi,Out kit use the chip stm32mp157C.The schematic show the PHY configuration.dts_file_relate2eth.txt: my device tree code related to the ethernet.loginfo.txt: show error information.Please advise how to solve it.Thanks,QiZhang
We are using OpenSTLinux as base distro for configuring and developing product on a custom STM32MP1 based embedded board. We plan to develop some testing and validation plans for the same. Just wanted to understand what sort of testing is carried out...
I have a design based on the STM32MP157C (technically the Octavo SiP) which simulatenously uses PA0, PA1, ANA0, and ANA1. While measuring analog signals on the device, I'm noticing that the CPU is biasing the ANA0 and ANA1 signals -- based on a measu...
Hi everybody,I would like to simulate a USB scanner device using libcomposite, so I modified the USB FIFO sizes in the DTS as follows:usbotg_hs{ u-boot,dm-pre-reloc; pinctrl-names = "default", "sleep"; pinctrl-0 = <&usb_otg_hs_pins_mx>; ...

Hi,I'm trying to bring up a custom board based on STM32MP151C MPU. The design is widely taken from the devkit.I'm booting from SDCARD and bootpins are set accordingly (b101).One thing that is changing is the I2C4 pins for PMIC interface (still on I2C...
Hello, I am working on a custom Boot Loader (SSBL) for the STM32MP157F-EV1 board to replace U-Boot in the boot chain (BL33), this is a requirement for my project. As I understand, to boot the Linux Kernel it is needed to provide 3 values through ...
Hello, I am currently working on bringing up a production board design with the OSD32MP157C-512M-BAA. The board design is very similar to the octavo systems osd32mp1-red boardSdcard is located on SDMMC1 with the same pinout.EMMC is located on SDMMC2 ...
Does ST-Linux run for any configuration of eMMC pins, i.e. if it is connected to SDMMC1/SDMMC2/SDMMC3 . or do we need to fix as per reference design / Dev kits.
