Troubleshooting 'USART Device Not Ready' Error on AVR Microcontroller with Zephyr RTOS
hey guys, I am trying to set up USART communication on an AVR microcontroller running Zephyr RTOS to send data to an IoT cloud platform. I have configured the USART peripheral in the file, created a Zephyr USART device binding in the device tree source file (), and wrote an application to send data over USART. However, I am encountering an error stating . I have verified the device tree source configuration to ensure proper USART peripheral settings, checked the pin configurations to match the hardware setup, and ensured the connections are correct. What could be causing this issue? @Middleware & OS
