Hi,What am I doing wrong that USART1 returns -2 during the probekernel.dts -> PINS usart1_pins_mx: usart1_mx-0 { pins1 { pinmux = <STM32_PINMUX('A', 9, AF7)>, /* USART1_TX */ <STM32_PINMUX('A', 12, AF7)>; /* USART1_RTS */ bias-disable...
Please tell me how to set the wake-up button (PA0:PWR_WKUP) as a return factor from LPLV-Stop mode and set STM32MP157f-EV1 to LPLV-Stop mode.
Hi all.I am adding a new user to my Linux image. After generating the image I verify the `/etc/passwd` on the rootfs and the new user is not present. When I try to login to this new user on the running image itself, it doesn't work. As I am using the...
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_...
