Hi Guys,

Hi Dietmar,

I have created a branch on github regarding two bugfixes which allow my 5 nanpoi a64 to connect to network again and also again use the second usb port, when booting, when using the latest (v2021.04) u-boot.

Thanks for sharing this. Please include the sunxi maintainers in your email, for improved response time.

https://github.com/DirkTheDaring/u-boot/tree/bugfix/nanopi-a64   The patch is attached to this text email.

Please include into u-boot official.

Kind Regards Dietmar

Please note that patches need your Signed-off-by:, to be eligible for inclusion.

In general we don't take DT patches straight to U-Boot, they need to go via the kernel tree first, then get synced back from time to time. I just sent an update for all A64s, that should fix your network problem already.

For the USB part: The sunxi Wiki is a bit controversial on this topic (talking about a hub at some point), so can you clarify the USB situation on the board? Is controller 0 connected to the micro-USB socket, and the two type-A receptables are connected via a hub? Or is it like the Pine64: the two type-A receptables are connected to controller 0 and 1, and the micro-USB is just for power?

If it is the latter, I wonder how this patch works for you? I need another U-Boot patch [1] (which I want to send out shortly) to actually enable this port 0 as a host port, and also rely on a DT change (now merged in mainline Linux).

Cheers, Andre
