Re: PINE H64 MODEL B emac0 rgephy fail to autoconfigure

[Shoichi Miyake <shoichi.miyake%gmail.com@localhost>]

Hi ringo, thank you so much for your feedback!
I only got a reply from you, and still I cannot use emac0 on my PINE H64.

I think you can see emac0 by ifconfig according to your information.
For my case, emac0 is not attached as a network interface.

I also have NanoPi R1S, but it has an issue that USB-A vbus is not
enabled, I guess.
emac0 seems working, using arrmbsd's nanopi neo build, maybe (sorry I
don't remember it clearly)

Today I took time to check if connecting the cable could change any
situation, but it didn't
Also, I checked dhcp or tftp boot from u-boot, but u-boot prompt says
> => tftpboot

I guess I should check H64 and H64 model B HW differences, and should
modify dtb for H64 model B.

I'm not familiar with recent evbarm with fdt, so I'd like to know how
evbarm guys retrieve fdt info from linux and
feedback to netbsd.
Any site good to know this information?

In the meantime, I'm going to connect usb ethernet or wifi adaptor
with H64 model B.

Best regards,
