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 ...
Hi,Does exist inside the Discovery kit with STM32MP135F board a text editor like nano or wim ?And if not how can I install it ?Thank you.Olivier.
Hi, Each time I reboot my Discovery kit with STM32MP135F borad I lost the network (IP V4 address). How can I set the IP address, Does exits somewhere a /etc/network/interface file ? Thank you, Olivier.
Hello I would like to interface the STM32MP255F to high-speed ADC like AD8285 or MAX1127 using these ADC's parallel interface. Is it possible to perform such interface while using the STM32MP255F GPIO lines? Thanks.
Hi All.I use discovery board of STM32MP157F-DK2 .So I want t to try read OTP Bits via STM32CubeProgrammer , But I find 2 errs.The err things search ST Community, I fund it. Can't read OTP bits on STM32MP157C-DK2 using STM32CubeProgrammer So I Try to...
Hi, Does myir MYD-YF135 development board support Bare Metal Project?
