Hello,I am working on a schematic for the STM32MP257FAI3 and the documentation seems to be inconsistent and/or incomplete regarding which ports go where with the built-in Ethernet switch. The data sheet says ETHSW has three ports in which the "The t...
Dear All, I have been working on communicating with LCD module by 3 wire, 9bits SPI. Firstly I implemented it by gpio. I can communicated with LCD module by 3 wire, 9bits SPI. But we encounter problem in total time in sending pixel data by SPI. We'...

Hi, I'm trying to change the value of the register RCC_RDLSICR (RCC reset duration and LSI control register, address offset 0x144). I need to change the Minimum Reset Duration value.In all power management/low power handling manuals for STM32MP15x li...
Hello, I hope you are doing well. I have developed a custom PCB with the STM32MP153AAB microprocessor. The process followed almost all the steps in the wiki for the STM32MP157F-DK2 discovery kit, however, some pins had to change due to the custom de...
We had a custom board with STM32MP135F series MPU on it, we just rolled out a new revision because we didn't connected PDR pin and it wasnt able to start after reset. But everything was booting correctly and all systems were working. Now in our new r...
Hello all,I was trying to build Linux kernel and push into my STM32MP135F-DK. For this, I was following the steps below link (Modify, rebuild and reload the Linux® kernel):https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-...
We have set PB7 and PE15 for I2c4 communication for PMIC in op-tee stm32mp135f-dk.dts.but we keep getting pmic error like this -I/TC: Embedded DTB foundI/TC: OP-TEE version: Unknown_3.19 (gcc version 12.2.0 (GCC)) #23 Mon Jan 8 10:50:26 UTC 2024 arm...
Hi, We are in a new project (first time with embedded Linux and device tree's in general) and i want to config my device (STM32MP151CAA3 on a custom board) to boot from FMC NAND flash (MT29F8G08ABACAH4-IT:) and i am having some trouble with the devic...
