I have enabled the FD-CAN device in the device tree with the following entry&m_can2 { pinctrl-names = "default", "sleep"; Template:Highlight pinctrl-0 = <&m_can2_pins_a>; Template:Highlight pinctrl-1 = <&m_can2_sleep_pins_...
Hello everyone, I use the STM32MP157A-DK1 on my project but I have a problem1- In the CubeMX, when you want to use a GPIO in output or input, why can not we select the context (cortex A7 or cortex M4)?2- When you set a GPIO as an output or input to C...
Hi,We are currently using the STM32MP1-DK1 board.We have tried several examples but we are facing some issues with the one using FreeRTOS (FreeRTOS_ThreadCreation) :We have no issues running the program on the M4 both in Engineering mode and Producti...
I have a STM32F746 discovery board and tried to compile a linux following this git:https://github.com/fdu/STM32F746G-disco_BuildrootAfter a lot of fiddling (because of file names not matching) I ended up with the files. According to wireshark the fil...
Hi, my custom board has OTG interface. So I reference the dk2 board to configure usbotg_hs as otg mode. But now, the otg interface only recognise on system starting up. It's can not recoginse the hotplug devices. Below is my dts code. My board use I...
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...
