The RX/TX delays for the Ethernet PHY on the Linksprite pcDuino 3 Nano
|
|
are configured in hardware, using resistors that are populated to pull
|
|
the RTL8211E's RXDLY/TXDLY pins low or high as needed.
|
|
|
|
phy-mode should be set to rgmii-id to reflect this. Previously it was
|
|
set to rgmii, which used to work but now results in the delays being
|
|
disabled again as a result of the bugfix in commit bbc4d71d6354 ("net:
|
|
phy: realtek: fix rtl8211e rx/tx delay config").
|
|
|
|
Tested on two pcDuino 3 Nano boards purchased in 2015. Without this fix,
|
|
Ethernet works unreliably on one board and doesn't work at all on the
|
|
other.
|
|
|
