Okay, I completely misunderstood this... and I lost the combination that turned the LED on :( It seems that PD6 is not exposed on the GPIO header [1]. It is defined on the FBGA on the pin map session of the datasheet [2]. So, I don't believe I need to short the pins to get it working, but somehow it at least powered on the Ethernet port. I wish I remember the combination.

On u-boot shell: gpio set pd6 then dhcp command works :). However, it doesn't get an IP and with static IP pinging doesn't work. It seems to be able to send BOOTP broadcasts but it doesn't get an IP... Combination was: u-boot config: CONFIG_SPL_SPI_SUNXI=y CONFIG_SUN8I_EMAC=y tfa config: SUNXI_SETUP_REGULATORS=1 (or just unset this) > > I still see: > > => dhcp > sun8i_emac_eth_start: Timeout > > And > > Net: PHY reset timed out > eth0: ethernet@5020000 > > Regards, > Anne Regards, Anne
