如果你只是修改设备树中的console设备,那么不管如何修改,输出日志的设备都必须是一个“串口”(在Zephyr中USB CDC ACM设备也是串口,后文会解释)。在build/zephyr/.config中,我们还可以看到: CONFIG_UART_CONSOLE=y 原来,在当前配置下,Zephyr默认的console后端都必须是“串口”设备。 我们可以尝试把console后端改成RTT...

Describe the bug We have a custom STM32H743 board configured for High-Speed USB CDC ACM Uart. The device will enumerate and we can receive data from the devices, but can't send data. We have tried it on a NUCLEO-H743ZI2 (full speed) and ...

Description: My device sends data out over CDC ACM. When the host PC reboots the device is not (power) reset so it stays in this state. The host is not able to reinit the device so it's missing from the device list. I use Linux as the ho...
