Hi shilesh,
See advice below, please!
1. Hardware connections
CPU_UART_TXD----->GPS_UART_RXD
CPU_UART_RXD----->GPS_UART_TXD
check it, please!
2. UART bandrate.
you should configure CPU UART bandrate to be the same as that of UART of GPS module.
3. GPS data format is NMEA
Generally speaking, we should decode GPS data via software, so I am not sure if GPS data can be showed directly on terminial via cat command.
4. Try to use minicom tool
you know we ofter use the serial tool on linux platform, so you can also try to reciew GPS data.
[Comment]
I have ever validated GPS module of u-blox on iMX6Q platform, no problem.(UART port / USB port both OK)
Have a nice day!
