DRV_ERROR of UART for the module of nRF52840 (v1.0), with the SDK v15.0.0_a53641a and SoftDevice version s140_nrf52_6.0.0

Hi,

When I developed with the board of nRF52840, I met up with an issue of UART. Sometimes, the UART will get a DRV_ERROR and crashed. Does anyone meet up with this issue before? Or is there any suggestions for it? I just used the example configuration of UART without enabling the Flow Control. And is there any limitation of the UART? for example, the highest throughout?

Thanks in advance.

Best Regards,

kaikai

Hi,

1. I don't think I have seen a 'DRV_ERROR' error before. I assume this is printed out on a debug terminal? In that case what is the complete and exact message that you see?
2. Do you only get the error when you are using the Softdevice?
3. What are you using the UART for?
4. The UART is tested with the baudrates given here (up to one 1M baud). 
5. Is this a custom project or do you see the error when you test standard unmodified examples in the SDK?
