Support,
I am using DA14583DEVKT-B. I haven't modified the OTP or FLASH. I am trying to serial boot from my connected processor via UART. I have P0_5 pulled high. According to what I read, I am expecting an STX on P0_4. There is a periodic signal there every 60msecs, but it doesn't match the STX character. Can you give me some guidance please?

I am attached the waveform. I have looked at the other UART pins and see a similar signal.

Thanks!!
Rich
