ESP-IDF UART NMEA parser example code not working while UART ECHO example do

[chriscckan]

I am using ESP32S3 dev kit with GPIO8 connected to a GSP module output at 9600baud, I have checked using PC the GPS output is working fine, NMEA msg can be received by PC. Also run the ESP-IDF v5.1 UART-ECHO example code, change the GPIO to 8 and the code can run and display the received UART RxD correctly. However, when I use the UART-NMEA parser example, updated the GPIO number to 8, it does not give any output at monitor.
Do any one experience this? and any way to fix it? I don't see any settings in the example menuconfig that could related to this, since UART-ECHO example code works perfectly which already shows the GPS, connection, my devkit board, are all working fine, it looks like the UART-NMEA parser example code is having some kind of bug?
