Hi!I have been reviewing the datasheet for the stm32mp157c and have seen that GPIO PG12 can be configured in a special function "ETH1_PHY_INTN"I would like to get more information about this mode, as it might be interesting to use it in future design...
Dears,I'm using STM32MP157C-DK2 board in production mode.Now I'm debugging the firmware in M4 core. However, when I insert a breakpoint at DMA interrupt handler and wait for a while, it will crash the whole system (A7+M4) and lead to the reset.I also...
Hi, I see STM32MP1 - M4 use "RCC_HSE_BYPASS_DIG", what does this mean? And from stm32mpcube, does anyone know the calculation below to get 209MHz? RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;RCC_OscInitStruct.PLL.PLLSource = RCC_PLL12SOURCE_HSE;RCC_...

I'm attempting to upgrade from ecosystem v2 to v4 and I've run into an issue where the USB OTG port no longer enumerates at boot time. Specifically, I no longer see any messages in dmesg regarding the dwc device, nor do I see anything in /sys/class/u...
i am using stm32mp135-dk board. i have installed STM32MP1-Ecosystem-v5.0.0 Starter Package now i want to create GUI with guizero what i do ?
I'm using STM32MP135f-dk, I'm having trouble installing keras: this is the output
Hi,For the past two days I have been trying to get a usb to serial adapter to work on this board, using both the starter package or buildroot. Whatever I do, it only shows up as new full-speed USB device number XX using ehci-platform. Is there someth...
Hi there,I have a custom board (with eMMC) that freezes in the middle of kernel loading:I am under the impression it is related with the rootfs.ext4, becuase it does not try the loading, but I am not sure yet.Flash table is the following (I don´t use...
hi expertsfor me this is the first time to use STM32MP1 family before i used powerpc-family CPU.with powerpc when i attached external ICs, in 8 bit CPU-A0 to external IC- A0in 16bit CPU-A1 to external IC-A0 with byte enable signalsis ...
