I am currently working with the Yocto BSP/meta-layer you provide for the Odyssey STM32MP157C board. I am trying to include the following packages in my image:CORE_IMAGE_EXTRA_INSTALL += "kernel-modules"CORE_IMAGE_EXTRA_INSTALL += "kernel-devsrc"CORE_...
I'm currently trying to boot STM32MP257 DK board.I managed to do it in the past with starter and developer package. I recently got back to it and tried to boot it again but without success.I tried to upload starter package to SD card and EMMC, both w...
Dear community, I've used yocto as my workhorse in the past a lot for other processor manufacturers. Now as I'm happily joining the STM world for linux I'm stuck. Maybe it is a too easy to miss question, but which steps I have to take for putting all...
Hello We are implementing the memory CRC generation sequence as described in the reference manual. According to the documented procedure, the following steps must be executed:1. Write 0x0 in CRCC[1:0] of RAMCFG_xCCR1 to deactivate the CRC.2. Write 1 ...
HiWe have a Custom Board based from MB1272 dev kit.Our system needs to connect the RGMII to a Marvell Switch Chip where that Switch is Managed MDIO from a different MPU.As such we need our STM32MP157 MPU to run in a fixed phy mode and use the RCC to ...
I would like to add a custom resolution hdmi display (1024x600) to my STM32MP257F-DK board is it possible as the dmesg output is as follows [ 930.525408] [drm:drm_helper_probe_single_connector_modes] [CONNECTOR:32:HDMI-A-1] [ 930.590130] stm32-di...
I have tried changing the ldo7 of stpmic25A in stm32mp257f-ev1,i have a custom board using stm32mp257fai3 and stpmic25a, where im using LDO7 for ethernet which needs 1v. so i tried experimenting the voltage first in stm32mp257f-ev1 EVK board and i ap...
Hi ST,We have developed a custom board based on the STM32MP257F-DK design, with the primary difference being the use of the STM32MP255DAK3 processor in place of the STM32MP257F. All other components and configurations—such as RAM, eMMC, and SD card i...
Hello.Is there any way to exclude some GPIOs from Linux, when I control them from M4 core and I don't want to give an ability to control them from Linux apps? I would like to exclude e.g. PG12. I tried this, which should be exactly for such use:&gpio...
Hi,I'm trying to understand what the viable options are.my goal is to be on more recent versions of kernel/uboot because there are features upstream that I need.my preference is to be following upstream.Current situation is that i'm using stm32s fork...
