Hi everyone,I'm attempting to optimize the boot process on my STM32MP157F-DK2 board by removing U-Boot and booting the Linux kernel directly via the FIP. I've followed the documented steps for STM32MP1:TF-A BL2 Modifications:Updated STM32MP_BL33_BASE...
I've been playing with the STM32MP257-DK, first looking at the start package. I have now delved further with the developer package, and ran into issues while following the README.HOW_TO.txt that is found in the linux kernel directory. I followed the ...
Hi there, I am working with the STM32MP135F-DK microprocessor and have already designed the user interface in Figma. Now, I would like to move forward with developing this UI. Which tool should I use to implement the UI on the STM32MP135F-DK? If I ch...
Dear ST Community,We are working with the STM32MP257F-EV1 evaluation board and using the Yocto Distribution Package for our software stack.Our intended boot sequence is:Boot starts from the Cortex-M33 core.The M33 firmware is responsible for triggeri...
When trying to boot from emmc I get the following error ...�NOTICE: CPU: STM32MP157DAB Rev.Z NOTICE: Model: STMicroelectronics STM32MP157DAB-INSTRUO-SOM INFO: PMIC version = 0x21 INFO: Reset reason (0x15): INFO: Power-on Reset (rst_por) ...
Good morning,fairly new to this mpu family, I did a bit of a research but I'd like to get pointed to the correct procedure to, for instance, change bit 31 of RCC_SECCFGR.This register would allow me for example to modify also PWR_CR1:BDP and PWR_CR2:...
Hello. I have a custom stm32mp135f board with emmc1(SDMMC2) and about to launch linux.(Minimized version of 135f-dk, no-sdcard, no-ethernet)I flashed the target with the CubeProgrammer normally.When the kernel loads userfs there says 'root '/dev/dis...
Hi,I am testing TBB on a stm32mp157f-dk2 platform, yocto, kirkstone, sp_min version. I am wondering on the FIP package creation and singing keys.FIP_SIGN_KEY -> is set to my private ROT key.After unpacking the "fip.bin" into separate files i get all ...
Dear ST Community,We are working with the STM32MP257F-EV1 evaluation board and using the Yocto Distribution Package for our software stack.Currently, the STPMIC2 is managed entirely by the secure world (TF-A and OP-TEE) on the Cortex-A35 side.Our goa...
Hi,We are developing a GUI using MATLAB App Designer and want to deploy it on an STM32MP257 running Yocto Linux.I have a few questions:Can a standalone app generated by App Designer run on Yocto? Does it need the MATLAB Runtime, and is that supporte...
