Hello Jim, There's a Perl script here https://github.com/openttp/openttp/blob/develop/software/gpscv/ublox/ubloxlog.pl that's for configuring and logging a ublox NEO-8MT. The caveat is that it uses a custom file format. However, the associated processing software, mktimetx, will read this and produce RINEX. You will need to produce a fake file of time-interval counter readings though, since mktimetx folds these into the pseudoranges (the software is for GPS common view time-transfer). As you will see, this is all running on a Beaglebone.
If you want to modify the script to produce native binary files, the equivalent script for the NVS NV08C https://github.com/openttp/openttp/blob/develop/software/gpscv/nvs/nv08log.pl does this, so you can use it as a guide for modifying - there are just a few lines to change.
