Well, when i try to transplant u-boot, I notice that the 1000M and 100M ethernet may use diff clk. Also the clk was init by u-boot. So the problems maybe the u-boot or the hardware.

Please check the packet error rate, If high, maybe the clk was wrong.

You can use clkmsr in u-boot to check the clk. It will show [ 125 MHz] CTS_ETH_RMII(11). Note: it may not very accurate. I try to adjust the code, but it not change.

Also, you can try to use ping in u-boot

ethmac {

It seems that only the RMII external clock source is defined in u-boot, and there is no RGMII clock source

The official manual says that mpll2 is the only clock for Ethernet
But after I disable DIV2, only modifying MPLL2 still has no effect
After the clock frequency is modified, it cannot be detected in uboot (it seems that there is only RMII in uboot)
Modified definition RGMII test results are the same as unmodified
I don't think it's caused by the uboot clk, Because using 3.10 kernel speed is normal
I think the clk configuration of the 5.x kernel isn’t compatible enough on the board v1.3

How did you use 3.10? Just modify /config/source/ or any thing else?

DIV2 seem not to be relatived to the ethernet. But when disabling it, the ethernet doesn't work in u-boot. Also it may not DIV2due to all of these register haven't described well in S805 manual. Some description I used are from S905 manual.

The kernel 3.10 comes from the onecloud's system
I also compiled the 4.19 kernel, but the network PHY can't be loaded normally,I also can't test iperf3

The kernel 4.19 test results are still the same。

NO, Bring the kernel out for testing on other systems.
iperf3's random data test is OK!
wget file test is OK!

I mean by accident. For example, run bootscript but failed. Then the user will try to change something and then saveenv.

This rate problem seems to be related to EEE or macirq.
The original kernel turned off EEE, but 5.x has turned on interrupts = <0x0 0x8 0x4>; EEE is not needed.
I try interrupts = <0x0 0x8 0x1>, and then turning off EEE is still invalid.

Interesting, I happen to set the initial variable, which makes it impossible to use.

遇到相同的问题,两块V1.3的板子,一块完全正常,一块出现上述问题,表现为下行速率正常,上行速率只有几百K,使用ethtool -s eth0 autoneg off speed 100 duplex full 强制将网卡速率设置为100M,上行速度正常跑满100M,下行折半只有50M。使用hzyitc
/
u-boot-onecloud 、 5.67直刷包带的u-boot 、 s805_flash_snail.img 均出现相同的情况。期待大神解决这个问题

我也遇到这个问题了,刷的最新的直刷包。

刷3.10内核的openwrt,内网速率正常。

目前还是怀疑是时钟。

可以注意到你们的测试结果均有重传现象。iperf3Retr 列即为重传次数。

这个时钟问题该如何解决呢?刚接触这个,不太懂,这个问题是内核的原因导致的还是我机器硬件的原因?要是硬件原因的话,我就不管他了

找到原因了,PHY那边的TX-delay好像不太生效。用MAC的就行。

 	pinctrl-names = "default";
 
 	phy-handle = <&eth_phy>;
-	phy-mode = "rgmii-id";
+	phy-mode = "rgmii-rxid";
 
 	mdio {
 		compatible = "snps,dwmac-mdio";
