Hello,
first and foremost thank you for maintaining and evolving Micropython, it made my pet project possible !

I'm using 32gb class 10 sd card from Philips for my pet project and stumbled upon an compatibility issues: without stop bit card does not work with the driver :-(
If that matters, product information is here.

With stop bit set - card works like a charm with the driver, i tested it locally.
Before it failed with: OSError: timeout waiting for v2 card.
