PINE64

Hello again,

I have the Quartz64-B v1.3

dmesg is reporting a raft of re-occuring errors with the built-in ethernet / NIC.

-These are all happening with: latest plebian, diet-pi, arch arm

[ 2777.053671] rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma
[ 2777.054322] rk_gmac-dwmac fe010000.ethernet end0: stmmac_hw_setup: DMA engine initialization failed
[ 2777.055169] rk_gmac-dwmac fe010000.ethernet end0: __stmmac_open: Hw setup failed
[ 2777.090016] rk_gmac-dwmac fe010000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0
[ 2777.185378] rk_gmac-dwmac fe010000.ethernet end0: PHY [stmmac-0:01] driver [RTL8211F Gigabit Ethernet] (irq=POLL)


as a result I cannot bring the NIC online. (tried ip link set end0 down/up and raises these dmesg output)

(fyi: if its useful, I can use an usb eth dongle and kernel recognizes it and I connect via that okay - usless it is usb3.0 port and another set of warning are raised ...for another port maybe)

I have tried using the PoE adapter I have for it and "normal" eth with DC power, and the same issue.

Any help much appreciated.
Thank you

More details on the issue of no ethernet.
(the wifi chip is receiving a signal btw, I can pickup access points)

So could this be related to a kernel setting: CONFIG_REALTEK_PHY maybe??

Kind regards
