After reading today's irc logs I've realized that ayufan has found the solution.

You need to change "rx_delay" in file "arch/arm64/boot/dts/rockchip/rk3328-rock64.dts".

From:
rx_delay = <0x11>;

To:
rx_delay = <0x18>;

After that change everything is peachy:

Code:

Hello, I have LibreELEC-ROCK64.arm-rb-leia21 installed on the Rock64 4GB and connected to the Sony Bravia 55xd85 4k TV. Everything works fine except that while watching a movie in random time I have something like connection lag (similar when resolution is changed) - video does not disappear but audio disappear for ~3 sec. It happens about every 5-25 mins. I've changed HDMI cable but it doesn't help.

Here is error that is written in log when it happens:
Code:

Same behaviour with both 4.4.103 and 4.15.0 kernel.

The problem is still there.  Sad

I don't think it's a problem.

From datasheet (http://opensource.rock-chips.com/images/...170309.pdf):

 GMAC 10/100/1000M Ethernet Controller
 Supports 10/100/1000-Mbps data transfer rates with the RGMII interfaces 
 Supports 10/100-Mbps data transfer rates with the RMII interfaces 
 There are 2 controllers, one is connected to internal FE PHY, the other is for external PHY device 
 Supports both full-duplex and half-duplex operation 
 Supports IEEE 802.1Q VLAN tag detection for reception frames 
 Support detection of LAN wake-up frames and AMD Magic Packet frames 
 Handles automatic retransmission of Collision frames for transmission 

 Ethernet PHY 
 Integrated IEEE 802.3/802.3u compliant 10/100Mbps Ethernet PHY 
 Supporting both full and half duplex for either 10 or 100 Mb/s data rate 
 Auto MDIX capable 
 Supports wake-on-LAN, EEE 
 100Base-FX support 
 Supports auto-negotiation


According to dmesg messages both Ethernet controllers are connected: first at 1 Gbit/s, second at 100 Mbit/s (max supported by internal PHY).

Seems that there is an issue in kernel 4.13 in handling the eMMC which is mmc0 (while mmc1 is the SD card):

Begin: Running /scripts/local-premount ... done.
[    3.003233] mmc_host mmc0: Bus speed (slot 0) = 200000000Hz (slot req 200000000Hz, actual 200000000HZ div = 0)

[    3.004816] mmc0: tuning execution failed: -5
[    3.005208] mmc0: error -5 whilst initialising MMC card

In initramfs only the SD card is visible but not the eMMC module which I use mainly:

I'm still getting exactly this mmc error in my build of latest kernel from ayufan/linux-mainline-kernel 59389fa34d4f (above 4.15.0-rc3). Would updating u-boot help? If so, which instructions to follow, these?: http://opensource.rock-chips.com/wiki_U-Boot

The above is exactly the output from serial console that I am getting now. Then I am being dropped into a maintanance shell (because my rootfs is on emmc). Do you recall the commit that fixed this problem (even approximately, I can search for it)? I posted the commit hash i'm using: does that hash include the fix?

Fixed by merging a patch from ayufan's linux-kernel into ayufan's linux-mailine kernel:

Two LEDs (white: Power, red: Stanby) on rock64-board are not displayed correctly.
Do you recognize that?

Concrete state is:
In kernel-4.4.103 both of them are always off, and
in kernel-4.15.0 both are always on.

When confirming Commits, the LED display has been changed several times.
And the contents of the last Commits are as follows.
Looking at this, I think that the above state is different from the expected behavior.

Finally,
The kernel-4.15.0 @ 0.6.13 setting is "heartbeat" & "mmc 0".
And this version will work correctly, I add this and report it.
