WZR-HP-G300NH: RTL8366S MII bus failure

Reported by: Tristan Willy <tristan.willy at> Owned by: juhosg
Priority: normal Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: WZR-HP-G300NH RTL8366S Cc:


My brand-new WZR-HP-G300NH appeared to load OpenWrt firmware but wouldn't give out DHCP leases (various OpenWrt versions). Being adventurous, I loaded up 10.03.1-RC5 testing (r26774) and attached a TTL serial port to it. I found out that the Realtek switch was not being initialized because the PHY management bus was failing. I've attached dmesg and boot output for review.

I imagine the GPIO changed on this board rev or some non-volatile memory went bad. Pointers for deeper debugging would be helpful, even if it means pulling out an oscilloscope.

Hardware: WZR-HP-G300NH - "A2 F0B" from the outside label. Silk-screen has revs V1 and A1.

Firmware: 10.03.1-RC5 testing r26774

Bootloader: BUFFALO U-BOOT Ver 1.07

Can you try the WZR-HP-G301NH image from trunk?

comment:3 Changed 7 years ago by Tristan Willy <tristan.willy@…>

Yep, that image works. I've attached a new dmesg in case it's interesting.

proper rtl8366s vs rtl8366rb switch handling is implemented in backfire as of r27816
