Hi st team, I am using the STM32MP135f-DK board and I want to enable CANFD drivers. First I checked if the CAN drivers are enabled in menuconfig using: bitbake virtual/kernel -c menuconfig (everything has been selected) Then I went to ~/STM32MPU_wor...
I could not complete loading a board following the WiKi How to load U-Boot with dfu-util.The process describes sending the tf-a file then the fip file however this always fails the correct procedure is to send the tf-a file then send the flashlayout ...
I am trying to interface DAC for the STM32 MP157D-DK1 board I have. I am just curious does the board even support DAC. I dont see any mention of that in the datasheet. That is the only option that I can select when I do DAC Enable for M4 Cube in cube...
I'm having a challenge moving changes from our Developer Package to our Distribution package. We've modified device trees using CubeMX for our board and have all the changes for TF-A, optee, u-boot and the kernel working in the Developer Package. Now...
The processor in this application is an STM32MP153. I'm using a Cypress FX3 emulating SRAM so I can use a read path of FMC->MDMA->AXI memory-to-memory and vice versa for the write path. Two independent hardware interrupts on the STM32 GPIOs initiate ...
Hello,I would like to make the system below using stm32mp157.- System Description -1. 100Mbps Full-Duplex Ethernet2. Cortex-A7 receives and transmits data from Ethernet on the PC. 3. Cortex-A7 calculates Ethernet data and sends the result to Cortex-M...

Running the code "MP13_BSP_BasicTemplates" in the DDR of the STM32MP135F-DK succeeds，But running the code "UART_Receive_Transmit_Console_A7" in the DDR of the STM32MP135F-DK fails（“USE_DDR” Macros added,Link text has been modified），Errors are as foll...
Hi,I am using a STM32MP151AAA3 and i need to control an RGB LED via PWM control (something like the WS2812B). I was looking into the PWM driver options for Linux side control and can't find options for PWM control for specific buffer sizes or anythin...
hello，my custom board use the same ddr as STM32MP135F-DK board. but when I debug the example DDR_Init_A7.erro occus when verify data in address 0xc0000000 + 0x80。as show in picture.pls help me
