Kit : HiFive1 Rev.B
Hello.
At first time I turned on the power, UART1 worked great.
But now it is not working
UART0 is still working, and It seems that ESP32-SOLO-1 has no problem due to UART0 message (see below)
ATE0–>ATE0
OK
AT+BLEINIT=0–>OK
AT+CWMODE=0–>OK
But when I connect UART1 in PC Application, UART0 is also stopped.
What is problem with this Kit? J-link OB Cause issue this problem?
Thanks.
Jim

Hi HKChoi,
Welcome to the forums. Please make sure you have the latest J-Link drivers installed on your host machine.
You can find the latest J-Link drivers at: https://www.segger.com/downloads/jlink/
Did you program the HiFive1 rev B board with a program that doesn’t produce serial output? You could try reprogramming the board with a program from FreedomStudio that has serial output such as a hello program.
