I need to provide 32kHz clock at MCO1 output pin on STM32MP157. I have successfully configured u-boot to provide this clock but as soon as kernel is started clock disappears. After some checks I have found that clock is disabled.My question is if it ...
Here the relevant parts of my device trees:******************TF-A*******************&pinctrl { rcc_pins_mx: rcc_mx-0 { pins { pinmux = <STM32_PINMUX('G', 2, AF1)>; /* RCC_MCO_2 */ bias-disable; drive-push-pull; slew-rate = <2>; }; };...
Hi everyone, I'm stucked into generating a stm32mp1 image with weston support. I 've followed the ST WIKI trying to generate the image, I made sure to have any depedencies installed and tried to rebuild twice the overall image starting from a fresh d...
Hi ,How we use the CRC unit on Linux in STM32MP1.My target is to use the CRC engine for verification of data at application layer.The link here mentions info about the crypto unit : Crypto API overview - stm32mpuBut in reference no module talks about...
Hi ,We are using stm32mp157a processor in our custom board.We want to configure Spi1 to Ethernet Switch(ksz9893rnxia) (Note : we have 2 slaves for Spi1 at Uboot level(Source code ver 2018.11). I have done Pin control and node creations in dts files.1...

Hello,I connected USB CN7 of STM32MP157A-DK1 to a PC with MS Windows.Sadly, the PC failed to find an RNDIS driver with:USB\VID_1D6B&PID_0104&MI_00\6&1164AF84&0&0000I tried to search for a driver, but I could not find any good.Both Windows XP and Wind...
We're working with the STM32MP157C SoC, and we're trying to troubleshoot the performance of a custom graphical application, using OpenEGL.It looks like Apitrace might be useful for this task, but I believe a copy is needed to run on the STM32MP157C, ...
HiI try to implement lan9303 switch with stm32mp1.My current achievement is working only one channelMy working dts isðernet0{ pinctrl-names = "default", "sleep"; pinctrl-0 = <ð1_pins_mx>; pinctrl-1 = <ð1_sleep_pins_mx>; status = "okay"; ...
Hi, I have been working with the stm32mp157d-dk1, and im trying to keep a circuit on, waiting to a digital signal output produced by a script, but when i put the board on sleep mode, the signal automatically power off because the gpio module turns of...
