Hello
This is a RFC patch series for supporting ethernet of H3/A83T/A64 SoCs.
For the moment, it is a bundle driver which handle:
- The MAC driver
- The internal PHY driver
- The internal PHY clock driver
I am sorry for the quality of this code, I dislike to release that at
this state
but for the moment I am blocked in every direction.
For A64 I didnt have access to such hardware, but according to
apritzel, the PHY need to be powered by the PMIC and for the moment
there are no support for it.
On my H3 (OPIPC) all basic functions works EXCEPT that frame
transmition is never sent on the wire.
On my A83T board (h8homlet), the PHY seems not powered. The PHY for
this board is an AC200 (an Allwinner chip without any datasheet)
accessible on the I2C bus.
What need work ?
- Finding why the internal PHY of the Orange PI PC does not send frame
on the wire
I don't think it's a PHY issue. I'm able to get some packets sent on the
wire:
- when doing ping from Orangepi PC, arp requests are seen on the other
end of cable but Opc won't get arp replies
- when doing arping from other end, I can get some replies from OPC
- wen doing broadcast ping from other end, I'm getting some repies from
OPC; the order of receiveing packages is wrong, times are high and
packages are lost but at least something is received
All I did so far is to modify sun8i_emac_xmit so tha none of bits 12-28,
except bit 24, is set in ddesc->st (this seems to be the only bit set by
BSP kernel, after brief look).
Best regards,
Krzysztof Adamski
