I have a board where a secondary CPU can select the STM32MP1's boot mode. On initial boot, the MP1 boots from NOR flash. I can then send a command to the secondary CPU which switches the MP1's BOOTx pins to enable engineering boot and resets the MP...
Recently for a design I had used STM32 MPU (part# "STM32MP157FAA1") with DDR3L (part# "NT5CC256M16ER-EK"). For simulating data & address lines from the IBIS model "ibis5_4gbddr3_e_1p35_0c~95c.ibs" in ANSYS for 500MHz frequency the source transmitter ...
Hi there, I am developing on an STM32MP157. We are trying to add two Linux virtual network interfaces that specify a VLAN ID using networkd. Specifically, we specify IDs 20 and 30. We do not specify VLAN ID 0. On boot, networkd successfully creates t...
I have a stm32mp135f board (I'm mainly interested in Linux capable SoC) and I am trying to learn something about trusted firmware a, optee, and secure boot solutions. Although the documentation is pretty decent I don't see how I could test the whole ...
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...
