STM32MP157 has a M4 core, so I am asking questions here in MCU section although the chip is belong to MPU. What I am trying to do is using M4's SPI4 to receive data at throughput of 20.6Mbits/sec, basically each SPI transition has 10.5KB block data, ...
Hi, I use two touch panels, one is ft5306 and another is tsc2007. These are under same i2c bus, the i2c2 controller.The ft5306 use PG8 as interrupt line. The tsc2007 use PI8 as interrupt ine. Here is my dts code for these devices.331 ft5x06:...
HI, I needs use timers2 to enable the pwm function. Then it will used as pwm-backlight for LCD. I wasn't known how to write the dts file. Could you show me some example code on this function?
We are trying to establish a ethernet connection with our PCs. But we are not able to do so.Do we need to custom configure the ethernet port in order to access it?Is there any prerequisite that we need to follow?STM32MP157C DK2
Hello dear ST community,I try to test FreeRTOS on the STM32MP1 for the Cortex-M4 and I encounter a problem: I've got the following warning: "When FreeRTOS is used, it is strongly recommended to use a HAL timebase source other than the Systick" Ok, bu...
Dear all,how can the Cortex-M4 MCU (bare metal or RTOS) exchange data fast with the A7-Linux system? Can the M4 access the DDR RAM of the Linux system, like the PRU on the Beaglebone can do? In the datasheet, there is a connection between the AHB bus...
Hello,I understand that many STM32 support USB OTG, so they can be USB hosts.What if I want to connect more than one device? Can I connect a USB hub and control several devices at the same time?
I am trying to add a kernel module for USB serial devices following: https://askubuntu.com/questions/168279/how-do-i-build-a-single-in-tree-kernel-moduleIn order to build just the module, not a completely new kernel , I would need the Module.symvers ...

Hi all,yesterday I just booted the amazing STM32MP1 DK2 device with a brand new Yocto build (st-image-weston). Can't find the fw_cortex_m4.sh . Is that available just in the STM32CubeMP1_Package or maybe I need to add another layer and build for anot...
