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

Hi Richard.Surprenant,
Since you haven't programmed the 583 with an advanced bootloader and your are following the standard UART booting procedure, according to the AN-B-001 the 580 should transmit a 0x02 (STX), i am not able to see why such thing could happen (not getting the proper byte when booting). Try to boot via UART using smart snippets, and check if you are able to boot using the Smart Snippets Booter also check if you probe the pin if you are able to get the same sequence of unknown byte.
Thanks MT_dialog
MT_dialog. After scratching my head a bit, I used realterm to look at the bytes and realized that there were two bytes being sent and the second one was the 0x02 (STX). Got it working. Thanks for the great support.
