Hi Stefan There is a PR opened on this exact topic: https://github.com/zephyrproject-rtos/zephyr/pull/8306 I suggest you have a look. Hih Cheers Erwan

#uart #flowcontrol #stm32

Hello guys, for the board STM32F407 I want to add pin PA8 25 MHz clk output to Etherent Phy. So that I add the following sentence (1) HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_1) into

Hi Pauli, If you are able to do what you want with Cube HAL then, to interface with zephyr, you just need to redefine the HAL callback (defined as weak in HAL drivr) in your zephyr application. You ca

Hi Josef To me, the problem look more like you didn’t include the CAN bus drivers when you built the kernel. Try running ‘make menuconfig’ and turning on the CAN bus, then rebuilding. Lawrence King Pr

Update: CAN bus is working now with my board. I had to move by board config into the Zephyr tree, then pinmuxing seems to work. I still do not know the root cause. My configuration (for CAN) was ident

#stm32 #can

Hi, the driver is built into the kernel, but what I found out yesterday is, that the pinmuxing is not set up correctly. And the STM32 CAN controller will wait until it has received some bits before it

I am trying Zephyr for first time and just want to get going on an example on an available evaluation board. I found a match for: https://docs.zephyrproject.org/latest/boards/arm/stm3210c_eval/doc/ind

Hi, Do you use a custom board based on stm32f412 SoC? Does the sample application "samples/subsys/usb/cdc_acm" works on your board? Yannis

Josef, The BOARD_ROOT works for me even with Stm32 boards. The pinmux is mandatory for alternate functions on st boards. You can run the following commad to set the board root: west build -b hvac_sens

Thank you Stefan, I'll take a look. I'll share here the simple code I'm doing but so far it is not working. The pins PA9 and PA10 of my STM32 are connected to an adapter to serial port (TX->RX, RX->TX

Hey Gustavo, I had the same problem some moths ago. Some help to get into it: 1.) check how uarts work in ZephyrOS(poll/interrupt driven) https://github.com/zephyrproject-rtos/zephyr/tree/master/tests

#uart #stm32

Hi Rodrigo, Yes the pins are okay. I can confirm the STM32 is sending a testing message (I connected the sending UART to my computer and read the input). Looks like the code to read the response is no

#uart #stm32

Hi everyone, I am new with Zephyr OS and I have a STM32 nucleo l4rz5i board. I'm using the default UART2 port for console output and I would like to use uart1 to connect to a LTE modem, to be able to

Hello Stefan,

#uart #stm32

Gustavo, Are you sure the pins are setup ok? You can try to use a ftdi connector to be sure. Do you have an dts overlay? Best regards, Rodrigo

#uart #stm32

I am always using a blocking way to write and a non-blocking way to read. Have you tried?

#uart #stm32

I am not at home. I’ll take a look if I can share that with you. De nada. Abraço, Rodrigo

You have to enable uart interrupt at the conf files.
