I am using the FMC peripheral of the STM32MP157 to access the FPGA, the FMC is configured as a Synchronous read synchronous write PSRAM. For the simplicity of the FPGA logic design I would like to have the burst reads and burst writes with CRAM page ...
Hi there, I'm developing a Linux Embedded system on an STM32MP153-based custom board. I have a problem regarding shutdown vs low power modes. I have a gpio (active low) that acts as a "final switch off" for the whole system (a.k.a. when that gpio goe...
Hello ST Dear ST Community, I'm currently trying to migrate my solution from stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24 to stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15 Im using a ST7789V Based LCD, and its working trough /dev/fb0 and ...
Hi,I am in the process of migrating from Yocto Dunfell to STM kirkstone and using layers from oe-manifest/default.xml at kirkstone · STMicroelectronics/oe-manifest (github.com).Also, I am using a modified Flashlayout tsv file:#Opt Id Name ...
I enabled fmc in arch/arm/boot/dts/stm32mp157f-dk2.dts:&fmc { status = "okay"; };And this is how i read or write its registers:static inline unsigned int readl(const volatile void *addr) { unsigned int val; __asm__ __volatile__("": : :"memory"); ...

we are following all step i.e mentioned in st.wiki. we have installed the stm32 cubeprogrammer but commant not working .at where i am doing wrong?
I am using stm32mp157d from stm32mp1 dk1 to work on an embedded project. When I boot bare-metal from A7, I have no trouble to read and write to UART 4, however I run into a wall when I try to user UART 7 or USART3. The HAL library works for UART4, so...
I have a python script. Do I want to launch it when the platform starts or by touching the screen?how to create a custom desktop shortcut on stm32mp157-dk2?
