Hi,We are using the STM32MP157f-ev1 board for our initial development and this is our first time using Linux kernel, we have been following the development package wiki links for building kernel, u-boot and tf-a. We used the STM32CubeIDE's inbuilt cu...
As stated in the title, I'm having trouble getting the ST-Link microUSB port connections to enumerate on the PC (Linux). I have two of the dk2 boards, and they have the same behavior. The only way they enumerate on the host is through the DFU mechani...
Hi,We are using stm32mp157a processorin Ubootv2018.11-stm32mp1-r2.1 version. In this DDR has 512MB of memory. We want to change DDR size 512MB to 1 GB ,how can we do that? and what are the files we need to modify for changing ddr size in uboot? Ple...
I have been told that the STM32MP1 fit that criteria. ie if the board is deployed to the field, then it is not easy to reverse engineer the SD card, ripping code and configuration details.Is this indeed true?What is the equivalent model to the Pi in ...
is there any way find dts config /sys/ file to check stm32mp1 in linux sdk ?cpu temp freq battery voltage vbat measurement.
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?
Hi,I tried to let "en.FLASH-stm32mp1-openstlinux-5.10-dunfell-mp1-21-03-31.tar_v3.0.0" work on the ODYSSEY STM32MP157C board.Please advise when will produce error : "Starting version 244.5+[ 5.236977] blk_update_request: I/O error, dev mmcblk1, sect...
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...
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...
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 ...
