Hello,I'm working with the STM32MP257F-DK using the Yocto Project, and I'm trying to enable I2C in my custom Device Tree.However, I’m facing an issue where the I2C controllers remain stuck because of power-domain pending states.Here is the relevant d...
Dear All,I would like to use MYD-LD25X development board, which uses the STM32MP257 I plan to run FreeRTOS on the M33 core and Linux on the A35 cores.Do you know if there are documents that I can follow to run FreeRTOS on M33 core and Linux on the A3...
Heyho, until now I have only used the STM32 MCUs, from L01x, to G4, up to H7 (single core), always bare-metal. We're now thinking about scaling up to some MPU, for more processing power, and also for some faster interfaces (mainly gigabit ethernet)....
I have a STM32MP257F custom board with a MT53E1G32D2FW-046 WT:C (4GB) memory.But when I'm booting the TF-A, then I get this message. Notice that this processor passes the DDR data(stm32mp_ddr_test_data_bus(void)) and DDR rw(stm32mp_ddr_test_rw_access...
I am working on STM32MP157F-EV1 and would like your assistance in enabling SPI-NAND support within the OpenSTLinux (Yocto) environment.Overview:Development Board: STM32MP157F-EV1Storage Target: SPI-NAND (Serial NAND)Flash Part Number: GD5F4GM8UEYJGR ...
Hello,I am working on the stm32mp257f-ev1 board and attempting to switch from the default USART2 early crash console output to USART6. I've successfully switch TF-A and U-BOOT console to USART6 but my OP-TEE console continuously outputs on USART2.I'v...
I am porting Linux to a board that uses the STM32MP255F.I used the BSP from the STM32MP257F-DK board.For now, I was able to get the LCD panel to display, but the weston-graphical-session did not start.When I added the following line to /etc/default/w...
In the STM32MP257F-DK Linux BSP, I believe that the initialization of the USB3DR peripheral devices (TCPP03-M20, CC1_EN, CC2_EN) is performed by the M33 core executing the following program:/usr/local/Cube-M33-examples/STM32MP257F-DK/Demonstrations/U...
I am trying to build the OpenSTDroid kernel, I first acquired the "STM32MPU Distribution Package for Android", Then as mentioned in https://wiki.st.com/stm32mpu/wiki/How_to_build_kernel_for_Android, I loaded the kernel & Then tried to build the dtb b...
I have used HSEM on STM32H7 very well.Recently，I test the HSEM of STM32MP257 in development mode， by JTAG/SWD，I can lock the semaphore by reading the HSEM_RLRx register via CPU1~3, but after power reset，when I write the HSEM_RLRx register to lock or ...
