Hello,

Here I found a bug in Nanopi M4.When I download BitTorrent file through ipv6(use Transmission,qbittorent...),the network will crashed.And I even can't ping it successful.When I connect it in local.I don't see any log in the network service.when I replace the network card(1000Mb) with a usb network card.The network work very good.And didn't appear any problem.I have tried all the linux system.the problem happen again.So I only can use the usb network card or wifi now.
Does anyone who know how to solve the problem???I would be very grateful for it.

I noticed a same problem in firely board 'http://dev.t-firefly.com/thread-11741-2-1.html'.if it is the same problem??
and he change the kernel in this way:
&gmac {
https://topdatingwebsitesx.com/chatspin
https://topdatingwebsitesx.com/random-talk
https://chatrandom.live
phy-supply = <&vcc_phy>;

phy-mode = "rgmii";

clock_in_out = "input";

snps,reset-gpio = <&gpio3 15 GPIO_ACTIVE_LOW>;

snps,reset-active-low;

snps,reset-delays-us = <0 10000 50000>;

assigned-clocks = <&cru SCLK_RMII_SRC>;

assigned-clock-parents = <&clkin_gmac>;

pinctrl-names = "default";

pinctrl-0 = <&rgmii_pins>;

tx_delay = <0x28>;

- rx_delay = <0x11>;

+ rx_delay = <0x1B>;

status = "okay";

};

I don't know if it work. didn't know how to change it in the kernel files.I am poor in this work.I also find that the nanopi m4 use the st_gmac driver for eth0 1000m.And I'm sure it has some bug.When I use the usb card drvier for usb card.Every thing work good.


thanks
