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

[kaikailiu_swi]

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,
