@eswakman Hi we haven't focused much on the development of m5cloud recently and theres a possibility that it could be phased out now our Ui flow platform is much more mature. If you wish to program in micropython please flash the firmware for the Ui flow website if it is not already flashed on your m5go. To flash the firmware please refer to these guides, if your on Mac https://www.youtube.com/watch?v=oEiFLsukAEE&t=54s or PC check out this link in our read the docs documentation https://m5stack.readthedocs.io/en/master/get-started/m5stack_core_get_started_Arduino_Windows.html Our readthedocs page will be updated very soon with lots of examples for uiflow blocks and python.
As for accessing the file system some users will use upycraft, I personally use Ampy and find it sufficient. The ampy tool you need to make sure you kill any currently running processes on the m5 from the command line before starting it. With ampy you can have full REPL functionality, you can put files and get them on to your computer and also run the python functions from the command line on your M5 in real time. For a primer on how to use Ampy please refer to this document provided by Adafruit https://cdn-learn.adafruit.com/downloads/pdf/micropython-basics-load-files-and-run-code.pdf
We understand the need for better documentation and are working hard on it, Please refer back regularly to m5stack.readthedocs.io and our youtube channel https://www.youtube.com/channel/UCozgFVglWYQXbvTmGyS739w?view_as=subscriber for tutorial videos
Thanks for your support
