Troubleshooting 'USART Device Not Ready' Error on AVR Microcontroller with Zephyr RTOS
Hey @Dtynin , I see you are talking about SPI, but if you're also working with USART and encountering the "USART device not ready" error, there are some common troubleshooting steps you can follow to resolve this. like
Verifying that the
USART node in your .dts file is correctly defined and matches your hardware setup, also ensure the compatible property is set correctly and that the USART pins (tx, rx, etc.) are properly assigned.
Make sure that the necessary configurations for USART are enabled in your prj.conf file. This includes enabling the USART driver and setting any required parameters.10 replies
