HiI see the STM32MP135 has an ISO7816 interface. Have you developed a compatible Linux device driver for the ISO7816 interface? There exist a software framework to use the SAM (Secure Module Access) Card connected to this interface?Thank you,
Hi!I am trying to have full secure booting on the stm32mp platform, using FIP and fitImage on a custom distribution built using Yocto with the meta-st-stm32mp layer.For the fit image signing, all steps are well described here [st wiki ] :https://wiki...
Hi!I have been reviewing the kernel log for the DK2 Kit, and I have noticed that the Ethernet configuration is in polling mode. [ 37.074899] stm32-dwmac 5800a000.ethernet eth0: PHY [stmmac-0:00] driver [RTL8211F Gigabit Ethernet] (irq=POLL) Is ther...
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
