【LX2160】增加SGMII新网口支持

作者 stormwind

一、Uboot支持网卡

1、修改设备树

vim components/firmware/uboot/arch/arm/dts/fsl-lx2160a-rdb.dts

&dpmac11 {
        status = "okay";
        phy-handle = <&sgmii_phy1>;
        phy-connection-type = "sgmii";
};

sgmii_phy1: ethernet-phy@3 {
                // RTL8211F PHY
                compatible = "ethernet-phy-id001c.c916", "ethernet-phy-id004d.d072";
                reg = <0x3>;
        };

2、修改驱动

vim components/firmware/uboot/board/freescale/lx2160a/eth_lx2160ardb.c

/*Begin:add by zhaobaoxing for sgmii*/
        srds_s2 = in_le32(&gur->rcwsr[28]) &
                  FSL_CHASSIS3_RCWSR28_SRDS2_PRTCL_MASK;
        srds_s2 >>= FSL_CHASSIS3_RCWSR28_SRDS2_PRTCL_SHIFT;
        /*End:add by zhaobaoxing for sgmii*/

/*Begin:add by zhaobaoxing for sgmii*/
        if (get_board_rev() == 'C') {
                setup_eth_rev_c(srds_s2);
                goto next;
        }
        /*End:add by zhaobaoxing for sgmii*/

/*Begin:add by zhaobaoxing for sgmii*/
        switch (srds_s2){
        case 10:
                wriop_set_phy_address(WRIOP1_DPMAC11, 0,
                                      SGMII_PHY_ADDR1);
                printf("warning: zhaobaoxing for serdes2\r\n");
                break;
        default:
                printf("SerDes2 protocol 0x%x is not supported on LX2160ARDB\n",
                               srds_s2);
                //goto next;
                break;
        }
        /*End:add by zhaobaoxing for sgmii*/

3、修改功能宏定义

vim components/firmware/uboot/configs/lx2160ardb_tfa_defconfig

#CONFIG_DM_ETH=y

二、Linux支持网卡

1、修改设备树

&dpmac11 {
          phy-handle = <&sgmii_phy1>;
          phy-connection-type = "sgmii";
};

sgmii_phy1: ethernet-phy@3 {
     // RTL8211F PHY
     compatible = "ethernet-phy-id001c.c916", "ethernet-phy-id004d.d072";
     reg = <0x3>;
};

三、板卡配置

1、修改rcw文件

vim components/firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2/rcw_2200_750_3200_19_5_2.rcw

SRDS_PRTCL_S1=3 #10G 8  #25G 17 CPRI-10G=3
SRDS_PRTCL_S2=10 #10 #CPRI 5 #-5GC #3#-BBU #5
SRDS_PRTCL_S3=3 #2

2、修改DPC文件

vim components/firmware/mc_utils/config/lx2160a/LX2160A-RDB/dpc-usxgmii.dts

 ports {
                        mac@3 {
                                /*Begin:changed by zhaobaoxing for 10G sfp+*/

                                /*End:changed by zhaobaoxing for 10G sfp+*/
                                link_type = "MAC_LINK_TYPE_FIXED";
                                enet_if = "XFI";
                        };

                        mac@11 {
                                link_type = "MAC_LINK_TYPE_PHY";

                        };
                        mac@18 {
                                link_type = "MAC_LINK_TYPE_PHY";
                        };
                };

3、修改dpl文件

vim components/firmware/mc_utils/config/lx2160a/LX2160A-RDB/dpl-eth.19.dts

connections {

                connection@1{

                        endpoint2 = "dpmac@7";
                };

【RK3568】gmac增加SGMII支持

作者 stormwind

一、SGMII+PHY

1、修改设备树

combophy

其中属性 rockchip,sgmii-mac-sel 表示使用的是哪个 gmac：

&combphy1_usq {
     + rockchip,sgmii-mac-sel = <0>; /* Use gmac0 for sgmii */
     status = "okay";
};

xpcs

&xpcs {
     status = "okay";
};

gmac0

&gmac0 {
     phy-mode = "sgmii";
     rockchip,pipegrf = <&pipegrf>;
     rockchip,xpcs = <&xpcs>;
     snps,reset-gpio = <&gpio2 RK_PC2 GPIO_ACTIVE_LOW>;
     snps,reset-active-low;
     snps,reset-delays-us = <0 20000 100000>;
     assigned-clocks = <&cru SCLK_GMAC0_RX_TX>;
     assigned-clock-parents = <&gmac0_xpcsclk>;
     pinctrl-names = "default";
     pinctrl-0 = <&gmac0_miim>;
     power-domains = <&power RK3568_PD_PIPE>;
     phys = <&combphy1_usq PHY_TYPE_SGMII>;
     phy-handle = <&sgmii_phy>;
     status = "okay";
};
&mdio0 {
     sgmii_phy: phy@1 {
     compatible = "ethernet-phy-ieee802.3-c22";
     reg = <0x1>;
     };
};

gmac1

&gmac1 {
     phy-mode = "sgmii";
     rockchip,pipegrf = <&pipegrf>;
     rockchip,xpcs = <&xpcs>;
     snps,reset-gpio = <&gpio2 RK_PC2 GPIO_ACTIVE_LOW>;
     snps,reset-active-low;
     snps,reset-delays-us = <0 20000 100000>;
     assigned-clocks = <&cru SCLK_GMAC1_RX_TX>;
     assigned-clock-parents = <&gmac1_xpcsclk>;
     pinctrl-names = "default";
     pinctrl-0 = <&gmac1_miim>;
     power-domains = <&power RK3568_PD_PIPE>;
     phys = <&combphy1_usq PHY_TYPE_SGMII>;
     phy-handle = <&sgmii_phy>;
     status = "okay";
};
&mdio1 {
    sgmii_phy: phy@1 {
        compatible = "ethernet-phy-ieee802.3-c22";
        reg = <0x1>;
    };
};

2、openwrt系统

驱动补丁：

113-ethernet-stmicro-stmmac-Add-SGMII-QSGMII-support 下载

3、其它系统

无操作

二、SGMII+非PHY

1、修改设备树

&gmac1 {
        phy-mode = "sgmii";

        rockchip,pipegrf = <&pipegrf>;
        rockchip,xpcs = <&xpcs>;

        assigned-clocks = <&cru SCLK_GMAC1_RX_TX>;
        assigned-clock-parents = <&gmac1_xpcsclk>;

        power-domains = <&power RK3568_PD_PIPE>;
        phys = <&combphy2 PHY_TYPE_SGMII>;

        status = "okay";

        fixed-link {
                speed = <1000>;
                full-duplex;
        };
};

2、驱动补丁

0001-ethernet-stmmac-dwmac-rk-Disable-Auto-Nego-for-1000-下载

三、回环测试

1000baseX 走强制模式，PCS会自己link up，而SGMII 需要协商link，这种情况一般是switch端没有固定好1000baseX模式的，之前rtl8310 switch端也是更新了很多次固件
我建议可以主控端先做一下回环，飞线要尽量短，
//driver 包产生
CONFIG_NET_PKTGEN=y
cd /proc/net/pktgen/
echo “add_device eth0” > /proc/net/pktgen/kpktgend_0
echo “pkt_size 1440” > /proc/net/pktgen/eth0
echo “count 99999999” > /proc/net/pktgen/eth0
echo “dst_mac FF:FF:FF:FF:FF:FF” > /proc/net/pktgen/eth0
echo “start” > /proc/net/pktgen/pgctrl
通过这种方式产生包，ifconfig 查看统计，确认能收到包。

【Ubuntu】systemback自定义系统镜像和系统备份

作者 stormwind

一、Systemback简介

Systemback是一个简单的系统备份和恢复应用程序，根据GPLv3许可条款发布。
Systemback的功能包括：
创建系统备份和用户配置文件。
将系统还原到以前的状态，就像Virtualbox的快照功能一样。
从现有安装创建可启动ISO文件。
将系统从一个分区复制到另一个分区。
升级软件。

二、安装 systemback

1、只在ubuntu16.04下在安装systemback

sudo add-apt-repository ppa:nemh/systemback
sudo apt update
sudo apt install systemback

2、在 18.04/19.10/20.04安装systemback

sudo add-apt-repository "deb http://ppa.launchpad.net/nemh/systemback/ubuntu xenial main"
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 382003C2C8B7B4AB813E915B14E4942973C62A1B

sudo apt update
sudo apt install systemback

3、可以从应用程序菜单启动Systemback，需要输入密码才能使用此软件，输入密码后，单击确定按钮

三、使用 systemback

1、创建自定义镜像

2、制作镜像

工作目录需要有读写权限（可自定义）
系统名称，可自定义，也可默认
包含用户数据文件（已有文件也会一共包含在镜像中，不过此时镜像可能较大，视实际情况处理）
创建新的，开始制作

3、制作中

制作时间主要参考以下几个因素：

系统硬件配置（越高越快）
包含的数据大小（越小越快）

4、老版本软件中，可能不会同时生成iso，所以可能需要把sblive转换为iso。对于小于4G的sblive可以直接转换，如下：

5、对于大于4G的可以采用udf文件系统。下面就是具体的解决方法了

解压 .sblive 文件:

mkdir sblive
tar -xf /home/systemback_live_2016-04-27.sblive -C sblive

重命名 syslinux 至 isolinux:

mv sblive/syslinux/syslinux.cfg sblive/syslinux/isolinux.cfg
mv sblive/syslinux sblive/isolinux

安装 cdtools

sudo gedit https://nchc.dl.sourceforge.net/project/cdrtools/alpha/cdrtools-3.02a07.tar.gz
tar -xzvf cdrtools-3.02a07.tar.gz
cd cdrtools-3.02
make
sudo make install

生成 ISO 文件:

/opt/schily/bin/mkisofs -iso-level 3 -r -V sblive -cache-inodes -J -l -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -c isolinux/boot.cat -o sblive.iso sblive

【lx2160】外围驱动修改

作者 stormwind

一、DDR调试

1、备份ddr_init.c platform.mk文件
2、修改ddir_init.c udimm参数，由codewarrior生成
3、在platform.mk增加CONFIG_DDR_NODIMM := 1

二、外设调试

1、IIC3调试
修改文件：rcw_2200_750_3200_19_5_2.rcw
修改内容：IIC3_PMUX=2改为0
2、增加OLED驱动
修改文件：fsl-lx2160a-rdb.dts
修改内容：增加
&i2c2 {
clock-frequency = <400000>;
pinctrl-names = “default”;
status = “okay”;
ssd1306: oled@3c {
compatible = “solomon,ssd1306fb-i2c”;
reg = <0x3c>;
//pwms = <&pwm 4 3000>;
//reset-gpios = <&gpio2 7>;
solomon,width = <128>;
solomon,height = <64>;
solomon,page-offset = <0>;
//solomon,com-lrremap;
solomon,com-invdir;
//solomon,com-offset = <0>;
//solomon,lookup-table = /bits/ 8 <0x3f 0x3f 0x3f 0x3f>;
};
};

3、增加5386驱动
注意事项：5386寄存器存在页的概念，需要先选择页，在读写寄存器值，
手册写着寄存器16位，其中前8位是页号，后8位是寄存器地址，数据手册存在误导。
修改文件：fsl-lx2160a-rdb.dts
修改内容：增加
si5386a: sync-clk@68 {
compatible = “newu,si5386a”;
reg = <0x68>;

};

三、PCI调试

1、pic802
原理图电容型号搞错

四、以太网
1、10G光口调试
restool dpmac info dpmac.6
修改文件：dpc-usxgmii.dts
修改内容：改变
mac@3 {
/Begin:changed by zhaobaoxing for 10G sfp+/
/*link_type = “MAC_LINK_TYPE_PHY”;
enet_if = “USXGMII”;
*/
/End:changed by zhaobaoxing for 10G sfp+/
link_type = “MAC_LINK_TYPE_FIXED”;
enet_if = “XFI”;
};

2、千兆网卡调试
修改文件：fsl-lx2160a-rdb.dts
修改内容：增加
rgmii_phy1: ethernet-phy@1 {
/* AR8035 PHY */
compatible = “ethernet-phy-id001c.c916”, “ethernet-phy-id004d.d072”;
reg = <0x1>;
eee-broken-1000t;
};
