First time trying to get OPTEE working on custom board. The boot stops when OPTEE panics NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-6.1-yocto-mickledore-mp1-v23.06.21 NOTICE: BL2: v2.8...
Hi,How can I install a USB serial adaptateur https://ftdichip.com/products/chipi-x10/When the usb adaptateur is connected there is not ttyS0 or ttyUSB0 !thank you.
Hello, We are currently in the process of bringing up and industrializing an embedded STM32MP1 board with eMMC as main data storage. We would like to flash the eMMC via U-boot using a tsv file. We have a couple of tsv files that are working correctly...
Hi,How can I install pyserial.py python modul on Discovery kit STM32MP135F.I would like also install pip Thank you for your help.Olivier
Hi all,I would like to design a device with the following features:Dual Gigabit ethernet,Encrypted communication: SNMPv3, HTTPS, SMTPS.I am looking for a SoC that makes it possible to achieve this functionality. After doing some research, I have foun...
I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.Wh...
I have a running system (based on bootlin buildroot) with kernel 5.10 and I wanted to update it to use the latest 6.1 and now I have a problem that the BL2 panics: NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelectronics custom STM32Cube...
Hi, I am encountering some issues while trying to configure the ADC DMA Buffer on the STM32MP135 board , when I execute the following:echo 1000 > /sys/bus/iio/devices/iio:device1/buffer/lengthecho 1 > /sys/bus/iio/devices/iio:device1/scan_elements/in...
Hello, I would like to integrate ethernet2 in my bare-metal project. I am aware that not only eth2 pins have to be properly configured, but also a 10th pin of MCP IO expander. However, the eth2 seems to be disabled after all. I am doing the same conf...
Hello.I am on porting STM32MP135F-DK Discovery Board source to STM32MP133D based customizing board.With bitbake build, the firmwares work well with STM32MP135F-DK.But with our developing board, it stuck on BL2 boot with panic. The main difference is ...
