Hi,
I'm currently trying to get the ethernet device of the Odroid C1+
up and running. Especially thanks to Martin's help I was able to
get the meson8b-dwmac driver to recognize the RTL8211F Gigabit
Ethernet chip.
Unfortunately, trying to set the eth0 device up with ip link
fails so far:
~~~
$ ip link set up dev eth0
RTNETLINK answers: Device or resource busy
~~~
And the kernel complains with this then:
~~~
[ 105.123705] meson8b-dwmac c9410000.ethernet eth0: device MAC address da:0e:a8:ec:a8:a7
[ 105.322726] RTL8211F Gigabit Ethernet stmmac-0:00: attached PHY driver [RTL8211F Gigabit Ethernet] (mii_bus:phy_addr=stmmac-0:00, irq=POLL)
[ 105.362725] meson8b-dwmac c9410000.ethernet: Failed to reset the dma
[ 105.363466] meson8b-dwmac c9410000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed
[ 105.372493] meson8b-dwmac c9410000.ethernet eth0: stmmac_open: Hw setup failed
~~~
I'm sorry, I'm rather new to this. What could be a common mistake
to cause such an error?
Regard, Linus
