Hi hope you're well. I got stuck on part 6.Compile kernel source code->Compile and install on the current source code directory->make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040 giving an error as below. Thanks in advance! CC drivers/usb/dwc...
Hi,we are using Stm32mp157a-dk1 board.We installed dfu-util tool in ubuntu. i didn't find any device (i.e,it shows no dfu capable USB device available). What may be the issue?Thanks in advance.
I found the following errors when I burned kernel alone and starterpackage. May I ask why this was caused? The kernel is through https://github.com/STMicroelectronics/meta-st-stm32mp/blob/dunfell/recipes-kernel/linux/linux-stm32mp/README.HO W_to.txt ...
Hi,I am planning to build an OTA update system for STM32MP1 which I have been using in my development. My question here is that linux based changes can be catered as part of *.swu files in case of OpenSTLinux for A7 , but how do we pack updates for t...
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...
