Hi there STM team!I need to build a embedded Linux image for a STM32MP15 target. My application has a QT GUI already implemented. What is the best approach to create this image? I know OpenSTLinux exist but I don't fully understand what's the advanta...
Hi all,I'm trying to enable the host functionalities for USB Port1 for MP135: I imported the Host Library and implemented some functions on usbh_conf.c file. Attached to the DK board I have a optic mouse.After some basic initialization I'm in the USB...

The following output seems to be the default: root@stm32mp2:~# cat /sys/class/remoteproc/remoteproc0/fw_format TEE However, for debugging purposes, I would like to turn off firmware verification, and make the remoteproc driver accept plain ELF files...
Hi,I am building my STMP157 board using the reference of "STMP15X-SOM" of Olimex. In that the RAM used is K4B4G1646D-BYK0, but I am unable to find the part number in online store. Can you please help me in finding the different RAM which can be used ...
Hello. I am trying to get a custom design using STM32MP135F to boot.Unlike the DK, it does not use I2C busses, and I2C is not listed in the DTS files as created by STM32CubeMX.I follow the wiki "How to compile the device tree with developer package" ...
I'm trying to install the distribution package but I'm at the point of the proxy issues and I don't know what to do. sudo apt-get update sudo apt-get install corkscrew git config --replace-all --global core.gitproxy "$HOME/bin/git-proxy.sh" git con...
Hello,I am developing on the STM32MP131FAE board in a bare-metal environment.This chip does not have internal Flash, so I am planning to load a bin file from external Flash at initial boot.The Flash will store two bootloaders and two main firmware im...
I have a small micro that needs to run before the MP157 is active. The voltage coming gin is 5V, but I need 3.3V. Is there an always-on LDO in the STPMIC1 for such purpose? I assume the internal LDO is not te be used?Do I need to program the voltage ...
Is there a way to build only optee, etc. up to the level of u-boot?It would help to ease board bringup, checking the dts effects, do some basic testing. Regards,Roland
