Hw (EEPROM) damage due to vibrations? Or some env variable missing? Basic behaviour changed

Hi all,

Thank you for your time and attention :-)

I've installed CaribouLite in a Raspberry Pi Zero WH and successfully ran the "capture" python3 example one day ago, with CaribouLite inserted against the Raspberry Pi Zero pins. It went O.K., I haven't paid much attention to this data yet but this is not the point.

Today the union Raspberry Pi Zero + CaribouLite Hat was mounted on a system that vibrates (e.g. a car), in particular vibrations occurred system was powered.

Finally the system was unmounted and the same capture example was ran again, but this time it returns the following. I really hope it's not EEPROM damage due to vibrations, but some missing config that only worked the first time because a lot of e.g. environment variables were correctly set freshly after installation. In any case, how can I check if EEPROM is O.K.? Thanks!

The error message is as follows (triggered during the execution of sdr = SoapySDR.Device({"driver": "Cariboulite", "channel": "HiF"})):

NOTE: this time the antenna plugged to HiF is a 50ohm directional one, i.e. a different one from the ones used the first day.
