Hello ST community. I am trying to understand the support the otfdec https://wiki.st.com/stm32mpu/wiki/OTFDEC_internal_peripheral internal device has or will have in the OpenSTLinux. Can anyone suggest reading material on supporting the otfdec for mp...
Section 5.1.1 Step 3 says that Copy the dts file from the directory: x-linux-gnss1-app\linux-kernel\patch\5.15\kernel to the kernelsource directory at <KERNEL SOURCE PATH>/ arch/arm/boot/dts/But in the latest X-LINUX-GNSS1 package, the linux kernel i...
I am struggling with getting a STM32mp25D board flashed, it hangs at BL32 (see output below). It does have one warning "WARNING: Could not enable VRSEL for vddio2", but I don't think that is relevant to the hanging at BL32 (but I could be wrong). I h...
Hi!I am working on the STM32MP257F-DK board for a robotics project. For this, I want to map some of the GPIO to M33 in order to control the motors while the Linux of the A35 will run the ROS software. From what I understood is follows:I need to custo...
SummaryI'm attempting to add support for a custom STM32MP135-based board (M5Stack CoreMP135) to Yocto using meta-st layers, but the u-boot-stm32mp recipe appears to enforce rigid constraints that prevent using custom defconfigs and device trees. Envi...
Hello,I tried to understand what does A35-TD does better than M33-TD flavor and vice versa. But I don't find enough information. The information that confuses me is it says A35-TD Flavor has Hard real time on Arm Cortex-M33. What does it mean operati...
I'm working on adding a custom STM32MP257 board based on the openstlinux distribution package, and I'm currently using the STM32MP257F-EV1 board. I'm having problems with booting on eMMC with a stm32cubemx-generated device tree. What I've done:* Crea...
We have a custom board with an STM32MP151A and STPMIC1. The PMIC is connected to I2C4 over pins PD12 and PD13.In the process of migrating our software from OpenSTLinux 6.0 to 6.2, I initially got stuck into an optee panic (attached optee-panic.log wi...
I have an issue with PMIC. It seems that Op-tee won't start och activate the PMIC. Do you know why? Any suggestion? The error is 0xffff0008 = TEE_ERROR_ITEM_NOT_FOUND.Notice that I have copied the DT from DK board. F/TC:0 0 probe_driver_node:543 Prob...
I have a platform where I need two different Linux distros, one kinda like Android's recovery environment, and one main application environment.They will have different packages, and probably also different init-systems, as the recovery environment s...
