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...
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...
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...
My goal is to use USART6 as debug output because I haven't route the dedicated BootROM pins of the USART2.Anyway! It seems that the BootROM is trying to read my SD card. First sequence:CMD and CLK of SDMMC1 seems to be talking to the SD card in a ver...
Hello I am planning to use STM32mp257Fak3 with DDR3L (16bit and 32 bit saperately),can you suggest some DDR part no and it's sonnection.
Hello, Happy new year !I create my custom board with STM32MP153C I try to boot but I have an issue. Starting systemd-udevd version 255.17^ root '/dev/disk/by-partuuid/e91c4e10-16e6-4c0e-bd0e-77becf4a3582' doesn't exist or does not contain a /dev. [ ...
Hi!I accedently used STPMIC25A instead of STPMIC25D when I want to boot A35 from SD card.According to AN5727 page 13, topic 4.1.8. it says that if the MP257 is going to boot from SD card, then the STPMIC25D must be used instead of STPMIC25A due to LD...
Problem descriptionI have a custom board based on STM32MP157FAA.The SD card boots perfectly in:ROM bootTF-A BL2 (FSBL)But once control reaches U-Boot, the SD card becomes completely unusable and U-Boot shows continuous: stm32_sdmmc2 mmc@58005000: cm...
I am trying to connect the STM32MP257F-EV1, following the guide on the wiki. Followed the LInux preparation. At startup, I get a blinking RED LD1 and steady green LED When start the laptop on windows, the device manager shows a DFU device a. But whe...
