I made a custom board with the processor STM32MP151AAC3 and own firmwire https://github.com/DanielMartensson/STM32-Computer/tree/main/STM32CubeIDE/STM32-Computer-Firmware . I have compiled the TF-A by using STM32CubeIDE. It was some bugs with the TF-...
Yes. I know that is possible to program the STM32MP by using ST-link V2 in CM4 inside STM32CubeIDE.I want to know if its possible to generate e.g .bin/.stm32 files from CM4 and paste them into a FlashLayout, and then later program it over STM32CubePr...
I am making a board using STM32mp151a.I want to make Linux OS for this machine.I refered to the web page below.https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machineHowever, Error happened on bitbake process.Please tell me the cause and cou...
Hi all,I have been trying to boot a custom ST32MP15 board, I get through TF-A and U-boot, but boot fails while Starting Kernel.I had some issues with external 24MHz crystal so I am using HSI to provide CPU clocks. On TF-A and U-Boot device trees I wa...
Hi All.I want to use the battery to power the RETRAM so that the contents of the RETRAM can be preserved even if the board is not powered.To do this, I connected the battery to the VBAT pin and set the "PWR_CR2_RREN" value to the "PWR_CR2" register o...
I've been having this problem for a while now. I open one of the trusted flashlayout (.tsv) files in STM32CubeProgrammer. I can connect to the target board over USB without issue. I click "Download" and it successfully downloads tf-a-stm32mp-serialbo...
I'm trying to generate dtb files (kernet, u-boot, tf-a) for a custom board with STM32MP157C (OSD32MP157C by Octavo Systems) following the instructions from ST (https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_Packag...
We made device tree for u-boot of stm32151c. But it can't work i2c4 for STPMIC1. PZ4,PZ5 is correctly connected to STMPIC1 with pull-up resistance.SDA,SCL has no signal.Attached is a device tree file.Please let me know what additional point to review...
I want to change the environment with STM32MP151. but I can't find about this information , question 1) How to configure STM32MP151 for uboot ? how to change to single core from dual core ?2) How to configure STM32MP151 for linux kernel?...
Hi All.I develop M4 Core firmware using a custom board based on STM32MP151C.There is no problem with SPI communication without using DMA. However, when DMA is used, waveforms do not occur the pins or only the NSS pins react, resulting in waveforms.I...
