Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Greetings,We're developing our product on our MYIR MYC-LD25X SoM based on the STM32MP257DAK3 MPU with 8GB eMMC non-volatile storage.As per our design requirements, I am required to enforce the STM32 MCU Equivalent of CRP Level 1 or 2 on our Non-Volat...
Dear community, I've used yocto as my workhorse in the past a lot for other processor manufacturers. Now as I'm happily joining the STM world for linux I'm stuck. Maybe it is a too easy to miss question, but which steps I have to take for putting all...
Hi!I having some issues with Linux at startup. It seems that it disabling the Bucks/LDOs at startup.vddio2: disabling vddio3: disabling vddio4: disabling vddcore: disabling v1v8: disabling v3v3: disablingWhy does this occur?Here is the complete outpu...
Hello, I am trying to load a kernel driver (.ko file) for a MIPI camera I would like to use with the STM32MP257F-DK. It's for the imx664, and no driver is present already. I have the source for the driver, and was able to compile it into a .ko file, ...
Hello,I was checking if it is possible to test my M33 NS code I generated using CubeMX would work in Developer Mode. However, the information found on internet suggest it being difficult as it requires the clock to be configured by M33 and also needs...
I have an issue were the Linux kernel is booting, then it just stops printing out messages from USART6.Meanwhile, optee, u-boot and TF-a is printing out messages from USART6. But not Linux after a while.What can have caused this?My processor is: STM3...
I am trying to build a custom Yocto Scarthgap image for a custom STM32MP153CAA3 board.I have followed the guide at https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine but have several issues.I have created a configuration in CubeMX ...
Hello,coming from OpenSTLinux 4.2 (mickledore) we are in the process of migrating to OpenSTLinux 6.2 (scarthgap).The process of how multiple partitions (bootfs, vendorfs, userfs) are "split out" of the rootfs appears to have changed considerably.Afte...
Hi,We are building Linux for STM32MP157D using Buildroot, and we are experiencing an issue where the boot process sometimes does not proceed from BL2 to OP-TEE, and sometimes OP-TEE does not proceed to U-Boot.Occasionally, the kernel does boot succes...
Hi everybody,For a project, we need to start the STM32MP257F in the M33 flavor, in order to perform some basic functions (GPIO, I2C, UART) in the lowest power mode possible (DDR unpowered, A35 in low power mode — i.e., no remoteproc nor Linux). The g...
