I am trying to collect images from a MIPI camera that is not supported by default on the STM32MP257F-DK, but for which I have a driver. With that driver, it's seeing the camera as an attached device, and I can see it in the dmesg output and also as /...
Hi,I recently just finished the Yocto Bringup of a custom STM32MP15FAA1. Everything seems to be working in my application. I am now looking to begin development of the M4 in which I need access to either SWD or JTAG to do lower-level development. Unf...

Dear All,I am using the STM32MP257F-EV1 board with the preloaded Linux image on the microSD card. The board powers up successfully (green LED ON, red LED blinking), but Windows does not detect any STLink Virtual COM Port even after installing STM32Cu...
Hello all,We are bringing up DDR4 memory on a custom STM32MP257D-based SOM. We have made significant progress but are now blocked on a specific PHY training failure that we cannot diagnose without access to the Synopsys PHY firmware streaming message...
I'm using the mp215 with ddr3l (x16) and an ISSI dram ic that is 8Gb (1 gigabyte) which means it's a dual rank configuration compared to a more typical half gigabyte. As far as im aware all 1GB ddr3 dram ic's are dual rank.In AN5723 6.1 Note it says ...
Hi, Just now I have done bringing up a custom board for STM32MP133/ STM32MP135 with OpenST Linux, with kernel 6.2:- The whole boot chain bring up from tf-a, uboot, kernel.- Configure PMIC and support DDR test.- Support FMC NAND, change flash partitio...
