Hi,I am trying to bring up an ILI9341 SPI TFT display on STM32MP257F-EV1 using OpenSTLinux Yocto (kernel 6.6.116).SPI2/SPI3/SPI8 work correctly with generic spidev nodes:compatible = "rohm,dh2228fv";and /dev/spidev* devices are created successfully. ...
I am currently using the distribution version:V5、rt 6.1.82-rt patch、stm32mp257I am using the TSN mode of the STM32MP257 switch and found that once I set the date, it reverts to the time before the setting after a period of time, and also causes a pro...
Hello all,We are bringing up DDR4 memory on a custom STM32MP257D-based SOM. We have made significant progress but are now blocked on a specific PHY training failure that we cannot diagnose without access to the Synopsys PHY firmware streaming message...
Hi~ My board gets stuck at the kernel stage during boot. I've referred to numerous related posts but failed to resolve the issue.The boot file versions I use are OP-TEE 4.0, U-Boot 2023.10 and Linux 6.6.116.The official device tree I referenced is s...
Hello,I have been trying for some time now to connect a Raspberry Pi 7" screen to my STM32MP157F development kit, as the screen that comes with it is too small for my purposes. I do not have a large amount of experience with embedded systems or worki...
Hi all,I have a board designed around the STM32MP153FAD (TFBGA257, 10×10 mm, 0.5/0.65 mm pitch, 257 balls). Since the MP153 does not include a DSI controller or GPU, I did not connect any DSI-related power pins or signals. Due to stock shortages, I ...
