Subject: [PATCH] sunxi: H6: Enable Ethernet on Orange Pi One Plus
|
||
|
|
|
||
|
|
Enable Ethernet on Orange Pi One Plus by using the correct phy for
|
||
|
|
Realtek RTL8211E instead of the Generic One. Also use CONFIG_MACPWR to
|
||
|
|
turn on ethernet on startup.
|
||
|
|
|
||
|
|
After this patch is applied, a few issues can be seen:
|
||
|
|
|
||
|
|
- there's still a PHY reset timed out error that doesn't seem to cause
|
||
|
|
any impacts to the overall connection
|
||
|
|
|
||
|
|
- sometimes the emac driver times out after reset (yellow LED turns on
|
||
|
|
and never blinks)
|
||
|
|
|
||
|
|
For future patches: for now, CONFIG_MACPWR is the only way to enable
|
||
|
|
Ethernet on boot. There's already code on the dts for using the 3v3-gmac
|
||
|
|
regulator. However, it is not probed on boot, so it only starts after a
|
||
|
|
"regulator status" command is issued.
|
||
|
|
|
||
|
|
More details about the troubleshooting on [1].
