I was able to build an image containing Chromium by adding meta-browser, meta-clang (dunfell branch) and meta-python2. I can verify Chromium built and was included in the image.The problem is when Chromium runs, it errors out with an error indicatin...
My custom board is based on stm32mp157a-dk1,remove the pmic and usb type c circuit,My porting steps are as follows:1. porting u-boot, verify that u-boot functions properly, compile the uboot trusted image, copy u-boot.dtb to FIP_artifacts/u-boot/ an...
We would like to implement a dual partitioning system and I am trying to find out if it is possible to have a secondary SSBL (u-boot) partition in trusted mode (eMMC).I don't see any problems for bootfs, vendorfs, rootfs and userfs. FSBL is already r...
I have a STM32MP157D-DK1 board. I downloaded design files and surprisingly found there were 56ohm series resistors on ddr address lines. Though series resistors are normally found on data and address lines for ddr1 or ddr2, I have never seen them use...
Hi,I wanted to ask if there is a possibility to have the same time domain on the M4 and A7 cores?To be a bit more specific: my STM32MP1 board synchronises time over Ethernet using PTP (and that works great!) but now i want to timestamp a digital inpu...
1. When I create an openamp-based virtual_huart0 on the M4 side for exchanging information，some code is as follows：if (VIRT_UART_Init(&huart1) != VIRT_UART_OK) { printf("VIRT_UART_Init UART1 failed.\r\n"); Error_Handler(); } VIRT_UART_Status...
Hi,I've noticed when booting one of our board designs with a STM32MP157C in openstlinux-5.4-dunfell-mp1-20-11-12 with Weston Wayland under the STM32MP157-Ecosystem-v2.1.0 that multiple times when the kernel is loading I'll see the message "stm32-dmam...
