I am using emmc in place of SD-card for custom hardware of STM32MP135FAE7. If FlashLayout_sdcard_stm32mp135f-dk-optee.tsv file will work using STM32cube programmer to upload all boot files??Whether all procedure will be same for boot sequence as we d...
I am trying to configure SPI5 on STM32MP151C where MPU is a master and ESP32C6 is a slave. The clock used in the device tree is HSI 64MHz. SPI driver is running with 2MHz configured and divisor in the SPI_CFG1 register is correctly set to 32. In the ...
Hi, I set MCO1 using HSE clock and get 8MHz working well (my HSE is 8MHz)But I need 16MHz or higher on MCO1, so I changed to MCO1 source clock by HSI but there is nothing.I tested other CSI, HSE, ... MCO1 work, except for HSI.I think there is somethi...
HelloI'm using stm32mp157aaa3 processor in our custom board.And I'm working on DDR3L with arm-trusted-firmware(V2.5) ddr3 routines as my reference code and reference manual(RM0436) and Application not(AN5168).When I am hard-coding the register values...
Hi,I'm trying to build core-image-minimal yocto project for my STM32MP157D-DK1 board according to digikey tutorial and I stuck at fetching m4projects dependency. Does anybody faces and resolved this issue?My build conf:Build Configuration:BB_VERSION ...
Hello all, As part of the evaluation of the 32MP15 series, I was trying to build the u-boot and TF-A binaries. I tried the u-boot SPL bring up and it seems to be working fine (except for failure to launch the Linux Kernel, as per your late updates). ...
I have a custom built STM32MP131FAF7T board and can't set my VOUT2. The only line that is down is my VDD DDR Lines since I can't program my PMIC (STPMIC1DPQR) to have the VOUT2 to be 1.35 volts instead of 1.1 volts. My VCPU is at 1.2V, VDD is at 3....
Hey, I'm following the Getting started tutorial and have some troubles at the chapter "Modify, rebuild and reload the Linux kernel":https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7...
I'm trying to use an ADV7280 videodecoder with DCMI and embedded linux on a board based on STM32157c-dk2. The decoder should output 720x576 picture resolution with the camera (PAL,CV) attached. However the DCMI seems to be in 'normal mode' which allo...
Hi all,We have a custom board based on stm32mp157f-dk2, with small changes. But we have an issue that the board will not wakeup after remoteproc0(m4) is turned off (cmd: echo stop > /sys/class/remoteproc/remoteproc0/state). When m4 firmware is runni...
