Hi all.I am confused about how I am supposed to provide power to the STM32MP257F-DK as it seems I am not providing enough power to the board when connecting the board to my PC via the STLINK/Power connector as the red Power LED is on and the Green LE...
The board seems to be very selective on the power provided on the STLINK port. Even with an USB 2.0 external powered hub, it often does not power on. The board seems to need 5V/3A. That would mean a USB C Hub, (USB 3.0 Type A max is 0.9A) or using...
Hi,And currently using the STM32MP157F-DK2 demonstration board using Open ST Linux (Kirkstone).And have an issue with the audio codec CS42L51 in that on startup the codec operates as expected, once any playback occurs, 4 seconds after playback stops ...
I got a STM32MP257F-DK with preprogrammed 16GB SD card and the Linux start-up works fine. When I'm building a Linux image based on openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 (DISTRO=openstlinux-weston, MACHINE=stm32mp2) and using a command "sudo d...
Hi,Is there a way in userspace of (remotely) identifying the silicon revision of an STM32MP157 part? for instance a file or shell command?thanks
In order to add a GNSS1 GPS module to my STM32MP257F-EV1 I added layers via bitbake by following the .pdf tutorial attached.The gnss_app application has been compiled using the SDK.I want to display it via: https://dsh-assetracking.st.com/So I follow...
Hardware setup:- STM32MP257F-DK- The OTP in the chip is burned with the correct OTP value and it is closed.- Connect CN15 USB Port to a Ubuntu Laptop.- BOOT0 = BOOT1 = BOOT2 = BOOT3 = 0- Power on the DEV KIT.Software:Enable Secure Boot + EncryptedROO...
We have changed the Yocto ecosystem of our builds from Kirkstone to mickledore.Everything works smoothly if all the components from the boot chain are built with the same ecosystem (either Kirkstone or Mickledore). Which means is, if TF-A, U-BOOT, Ke...
Hi,I have a custom Board with a STM32MP157C marked 'B' with an attatched SD card and an eMMC (one from ISSI).First of all I am aware that this revision is having the errata 'eMMC boot timeout too short'. I also read through this post: https://communi...
Hi,according to CubeMX the LVDS-pins of the STM32MP25 are not multiplexed, means there is no alternative function available for them.As for my application all this (multimedia) stuff is not needed: is there a possibility to use one of these pins as g...
