just after flashing software (required)
Describe the bug
the GNSS does not respond to commands. I tried also with own software, so after sending a command via serial interface, the GNSS chip (CXD5603) dows not respond. No NMEA output. Only 1 sec impuls can be observed on PB5. Didn't find the same problem in the closed issues
To Reproduce
I have two out of five T-Motion boards which show the same behavior.
Expected behavior
get respond from GNSS chip including NMEA sentences
