Hi, just tried it and it works fine on my system. are the modules installed? You could check using: west list | grep hal_stm32 Best regards, Yannis

Hi, You don't need to add it. It exists in dts/arm/st/l4/stm32l471.dtsi To enable it just add the following in nucleo_l476rg.dts or an overlay file: &spi2 { status = "okay"; }; Yannis

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

#stm32 #usb

Hi Roman, you need to update boards pinmux.c file to add the I2C pins. You could check olimexino_stm32 board's pinmux file for reference. Yannis https://github.com/zephyrproject-rtos/zephyr/tree/d6e3f

Hi Joe, I will try to test the sample on my boards in the next days. The default HID endpoint is 0x81. Is it configured? Best regards, Yannis

Hi Joe, please consider creating a PR to enable USB on nucleo_f411re. Best Regards, Yannis

Hi Joe, USB is not enabled on nucleo_f411re. It should be easy to enable it. Check the following link https://github.com/zephyrproject-rtos/zephyr/pull/6535/files Best regards, Yannis

Hi Nicolas, did you also update dts.fixup file in boards directory? Best regards, Yannis

Hi, I just test I2C_1 using the latest master branch. I am driving an oled display using I2C_1 on 96b_carbon just fine in both interrupt and polling modes. Does interrupt mode works for you? Yannis

I don't think the problem is in i2c_burst_read. If you check the driver code, STM32 I2C driver doesn't use msg.flags to generate a stop condition. I tested the I2C driver on olimexino_stm32 (stm32f103

Hi, You are right, the first `if` with `data.len = 1` should be nack and not ack (probably I made a typo during driver development). In case a single byte has to be received, the Acknowledge disable i
