Seems fine. You could drop the 'v1' as I only used that to differentiate with the V2. OTOH, I'm always 'struggling' how to identify the original NanoPC-T6. I do like consistency, so mimicing the setup for R6 is nice :-) > Note that I will not make the v2 board part of this patchset since I > am unable to test it. But as you said we can take it into account now. Agreed. My concern was about trying to prevent another complete reorganization once someone decides to upstream support for V2 (2603). >> https://wiki.friendlyelec.com/wiki/index.php/NanoPi_M6#Schematic.2C_PCB_CAD_File >> https://wiki.friendlyelec.com/wiki/index.php/NanoPi_M6V2#Schematic.2C_PCB_CAD_File > I did a quick comparison of the schematics and noticed the following > differences: > * New CODEC; ES8389 > * A new "User" button connected to a gpio line. > * Different USB 2.0 hub: CH334P (may not be relevant for DT) > * Different USB PD power solution (not relevant for DT) At the end of the M6V2 product page, there's also a comparison with 'V1': https://www.friendlyelec.com/image/catalog/description/M6V2_en_13.jpg It's under the heading 'Comparison', but it's part of the picture so you can't search for it. Dunny why FriendlyElec does that, but they do it consistently.
