But you are > right that this README doesn't cover these. I didn't know that. In fact, I specifically ordered the no-eMMC version based on the information on the web in order to make my life easier.

However, the PDF manual on the web [1] mentions 11000 on page 10. [1] https://wiki.solid-run.com/lib/exe/fetch.php?media=a38x:carrierboard:docs:sr-a38x-clearfog_base-manual-rev1.1.pdf
