Hi ST Community, @Erwan SZYMANSKI I’ve been working on integrating a Qt example from ~/Qt/Examples/Qt-6.7.2/quickcontrols/imagine into my custom Yocto layer for an STM32 board. I created a recipe for this and updated my local.conf accordingly. After ...
The 'of_device_id' in my module is as follows:static const struct of_device_id gcnano_of_match[] = { { .compatible = "st,gcnano" }, { .compatible = "vivante,gc" }, { /* end node */ } };In the device tree:compatible = "vivante,gc";When usi...
Does anyone know how to view and modify the current CPU frequency of STM32MP157D? I also cannot use the following command: root@stm32mp1:/sys# cat /proc/cpuinfo processor : 0 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 48.00...
x linux-5.15-stm32mp-r2 for our puposes. I have also attached the pps-gpio source code in case it is useful.
Hi, when trying the new ST BSP release base on linux kernel 6.1.82 on my stm32mp157f-dk2 I noticed that the legacy framebuffer support is not working anymore.this was working perfectly on the previous release with linux kernel 6.1.28.I didn't succeed...
The Linux version I am using is 6.1.28, and the chip is STM32MP157D. Currently, the USB-OTG chip uses FUSB302. I tried the online driver and found some issues. When I plugged in the USB device, there was no response. However, setting the USB-OTG to h...
I have only one MMC, in this case it's an eMMC on SDMMC2. I have some issues when I loading over the TF-A and the FIP.bin file.Update:I have change the clock frequency to 49.5 MHz and measured the v3v3 signal to 3.3V and the vdd signal to 3.3V as wel...
Hello We have built OpenSTLinux(Openstlinux-6.1-yocto-mickledore-mp1-v23.06.21) for stm32mp157f-dk2 Board and I have built st-image-weston image. Iam new to this Yocto,so I request you to help with the following:How to make changes in dts & dtsi file...
I never heard about the PER clock. I'm looking inside CubeMX, but I don't see any PER clock at all. I guess it's periferial clock. So how do I start it? My U-boot won't boot. I guess that if PER will be like 24 MHz, then U-boot will continue. Or am I...
Custom STM32MP151A board with 512MB DDR2.I am trying to write via UART communication with STM32CubeProgrammer, but BL32 processing does not start.What should I do to investigate the cause? [2024-01-12 14:11:52.591] NOTICE: CPU: STM32MP151AAC Rev.Z[20...
