I have a STM32MP257 custom board and I'm listening on UART6.When I boot, I get nothing. No messages or other text. I have not yet implemented any Linux onto my SD-card.The issue is that I have my USART6 boot pins on PF13 and PF14, instead of PF4 and ...
Hi,I am trying to work with the USART6 which is connected to is connected to PF13 (TX) and PF14 (RX) on the extended GPIO.It looks like the SCRIF does not allow access to this USART, wven though the OPTEE configuration seems to enable it:from optee/....
Hello ST community,I’m an embedded software beginner working with the STM32MP257-DK board and OpenSTLinux (Yocto). I need help getting USART6 working on the external GPIO connector (PF13 = TX, PF14 = RX — CN5 pins). I have rebuilt device trees and co...
I installed the latest STM32CubeProgrammer in WSL on windows 11: the GUI has issue to load so I'm using the STM32_Programmer_CLI.However the flashing would fail most of the time:---- log output begin -----....Sector[0] downloaded successfully...File ...
I have built a custom board by using STM32MP257F and I want to boot on USART6. I have not succeed to boot on USART6 when I compile my own fsbla by change the device tree of TF-A.I got a suggestion from ST Dev team to run this ROM tracedump wiki-stm32...
Please check STM32MP157F-DK2 no function issue after STM32MP157F-DK2.#1. After receiving the STM32MP157F-DK2 board, I connected a 5V/3A Type-C Power Adapter to CN6 and verified Linux boot and operation. LCD operation.#2. Updated the Linux image on th...
Hello,I'm stalling with an issue with Optee on a custom board with 256 MB of ram and an STM32MP135D.The environment was working with the DK (MP135F and 512M ram).I followed the guide for the configuration with 256 MB of ram (https://wiki.st.com/stm32...
Product:MCU/SoC: STM32MP2Description:In our ST Linux environment, the hantro-vpu driver registers:/dev/video5 -> VDEC (H.264/VP8 Decoder)/dev/video6 -> VENC (H.264/VP8 Encoder) We want to implement direct V4L2 API usage for H.264/VP8 encoding and dec...
Hello,we have a STM32MP157C processor MAC connected to MAX24287 PHY by RGMII interface, what we see that the GTX_CLK duty-cycle higher than 55%Could we decrease this value somehow?Thank you.Zsolt
Hello,Currently I'm working on a project that requires a synchronized clock signal between multiple devices connected through Ethernet.The logic solution for this is PTP, and using linuxptp I was able to archive synchronous PPS on PG8 pin between dev...
