Regarding Stm32mp157a_Dk1
We are using stm32mp157a_dk1. we want to know cortex_A7 core0 is in secure or non secure mode? How will come to know processor mode is in secure/non secure? If it is secure how to change it to non secure?

Resolved! OpenSSL performance expectation
I am wondering what number I should expect in terms of encryption performance with STM32MP157C. Below is that I getOpenSSL 1.1.1l 24 Aug 2021 # openssl engine -c (devcrypto) /dev/crypto engine [DES-CBC, DES-EDE3-CBC, AES-128-CBC, AES-192-CBC, AES-2...
How to drive an output GPIO as HIGH even during sleep / suspend ?
Hi ST Community,We are using STM32MP157C-DK2 board and OpenSTlinux Firmware (v3.1-Openstlinux-5-4-dunfell-mp1-20-11-12) for our development. We have a requirement to drive the Blue LED (LD8) always ON even during sleep / suspend. Currently the GPIO P...
Resolved! On the STM32MP1, when booting from serial NOR flash, the STM32 MPU Wiki states "In dual mode, BK1_NCS shall be connected to BK2_NCS on board." Should MPU BK1_NCS and BK2_NCS GPIOs actually be connected, or rather is BK2_NCS GPIO unused?
I'm just confused since other kits (ex: STM32H750B-DK) have provisions for jumping the 2 lines together, but the wiki does not indicate the BK2_NCS GPIO (from the MPU) is even used by the BootROM. I wanted clarification of the statement made on the ...
Resolved! there's a way to update a microSD partition without touch the boot mode switch?
Hi, i'm using Yocto to build a custom openstlinux image for a stm32mp157d-dk1, but i would like to upload the image using the mass storage mode, enabled with u-boot, or something like that.
MicroSD initialization timeout. When inserting the sd card, dmseg shows "mmc0: error -110 whilst initialising SD card" With some logs, i see that mmc_send_app_op_cond is the function that timeouts.
My device tree is the following:&sdmmc1 { pinctrl-names = "default", "opendrain", "sleep"; pinctrl-0 = <&sdmmc1_b4_pins_a>; pinctrl-1 = <&sdmmc1_b4_od_pins_a>; pinctrl-2 = <&sdmmc1_b4_sleep_pins_a>; cd-gpios = <&gpiog 1 (GPIO_ACTIVE_LOW | GPIO_P...
