Dear all, I was trying to setup the NVIC for EXTI for certain pins on STM32MP257F over CubeMX. However the nomenclature in CubeMX confuses me a lot. As I know there are two EXTIs: EXTI1 and EXTI2 which completely changes when we look into NVIC there ...

Hello! I'm attempting to build a custom bootloader for the STM32MP133C, heavily reliant upon the STM32MP13XX hal layer and then provided cmsis_core and cmsis_device_mp13 packages/pieces. I'm attempting this on IAR (company decision) which has added s...
I'm in a bit of a pickle. I got a MIPI DSI screen with 1200x1920 resolution. It turns out for SMT32MP25x max vertical supported resolution is 1536. But datasheet says this. Some over-target non-guaranteed use cases are possible, but with specific co...
Hi, I'm using a STM32MPU157C with linux 6.6, uboot, OP-TEE 4.0 and TF-A 2.10 and I have a Device Tree (for linux and uboot) which declares the USB OTG node as following : &usbotg_hs { compatible = "st,stm32mp15-fsotg", "snps,dwc2"; pinctrl-names = ...
Hi,Greeting!I am working on the STM32MP135F-DK board and trying to interface a 4x5 matrix keypad using GPIOs.I configured the keypad as follows:Columns (C1–C5):C1 → PE1 (Pin 37)C2 → PF11 (Pin 35)C3 → PF9 (Pin 33)C4 → PD13 (Pin 31)C5 → PE6 (Pin 29)Row...
I am running into issues building for the eMMC storage target for the `stm32mp25-disco` MACHINE type.I thought that adding "emmc" to `BOOTDEVICE_LABELS` should be enough to trigger building emmc flashlayout files. Is that not the case? I haven't foun...
