Thank you for your feedback ! So what to do ?
If you can confirm that eMMC is more stable than SD/SD card, then I am ready to buy one. I really want to boot from the board with updated kernel to be up-to-date about security, and have SATA support.
Could you please confirm that eMMC is a better solution ?
If so, is it possible to boot from eMMC ? and how ?
Sorry to insist, I really like this open-source world, and I can repeat from a simple tutorial, but from pages and pages of documentation (to do "A", you need to know how to do "B", and to do "B", you need to know how to do "C", etc.), I need more experience, I think you can understand it.
Please feel free to feedback, thank you again.
