Keep getting uart error at UART0_IRQHandler at app_art_fifo using app_trace

Hi,

I am wondering what to do to fix the error I have been getting while trying to debug my project. I am using app_trace for logging. I would often get an error on the UART0_IRQHandler. I is happen more often now for some reason. It comes and go. My speed is 460800 No flow control TX buffer size 512 I believe the app_trace is using FiFO buffer.

Thank you

If you do not have flow control then overflow errors are bound to happen at the speed you mentioned. The driver is not reading fast enough, are you using having BLE radio activity along with this?

What do you think the setting should be? what Baud and buffer size should i set it at for non flow control?
