Hi all,We are currently trying to add a QSPI device to the STM32MP135F-DK board. Using STM32CubeMX, we selected PB2, PF8, PF9, and PF10 as the QSPI pins and generated the Device Tree accordingly. We then built the image using openstlinux-6.1-yocto-mi...
I aim TO drive a mipi display screen on STM32MP257F-EV1, so I have to understand the DRM framework.After flash the new firmware, I found that the modetset always shows errors, so I want to confirm whether the support in this aspect is OK? But watchin...
Is it possible to use an STM32MP257F-EV1 miniPCIe with an external low-speed graphics card? I want to use it to run the PS2 emulator.
HelloI currently run on hardware STM32MP135f-DK and am preparing for running a custom HW.When assigning PA12 as a gpio-key in the devicetree,I get this error on boot:[ 3.544391] genirq: Flags mismatch irq 45. 00000083 (my-input) vs. 00002088 (0-0021)...
Hello,I am using meta-st-stm32mp which points to mickledore and is using linux 6.1.82.I would like to use linux 5.10.xx instead, so I got the kernel recipe from Dunfell Branch and put itin a custom recipe, after that I set in my local.conf the follow...
Hello,I am currently working with an STM32MP131 in a bare-metal environment and utilizing external DDR3. For this, I am using the HAL library, and in most cases, it works as expected. However, I occasionally encounter an issue where the HAL_DDR_Init ...
We are working on building a gateway using the STM32MP1 and the RAK5146 concentrator module with the RAK5146 Pi Hat, utilizing the OpenSTLinux Dunfell distribution (v3.1.11).While building the st-image-weston, we encountered an error during the compi...
Dears,I'm using STM32MP151 and have a uncertain quesion.In my cases, Both A7 and M4 need to access the register ETH_MACSTSR and ETH_MACSTNR to get time stamp.It's required to enable the ethernet clock on both side before accessing these registers, i....
Deaers,I'm using stm32mp151fad and would like to transfter sram data to ddr in M4 side. I refer to the logic analyzer example https://github.com/STMicroelectronics/logicanalyser. The sram data could be copied into ddr immediately. // mask and trans...
Hi:Recently, while developing an application on the STM32MP257, I tried to remove Weston. After removing the weston-start application, other apps could no longer be displayed. Additionally, when using modetest to check, I noticed that the CRTC sectio...
