Prerequisites: The board should be running Linux and connected to terminal console.

Note: For log level debug support, the restool version should be LSDK-2003-RC1 or above and MC version should be 10.20.0 or above.

To check restool version:

$ root@localhost:~# restool -v
restool LSDK-20.04

To check MC version:

root@localhost:~# restool -m
MC firmware version: 10.24.0

For debugging, use the ls-debug script available in the LSDK rootfs. There is no need to create the debug object.

ls-debug -h 

For example, to enable logging in console with log level INFO:

$ ls-debug --log=on --console=on --level=2              
dpdbg.0 created
DDR log printing ON
UART console printing ON
Log level set to 2
$ root@localhost:~# ls-debug --memory
Memory dumped information available in MC log/console
$ root@localhost:~# cat `find /dev/ -name "*mc_console"`

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+*/
                                /*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";
                        };

                        mac@4 {
                                /*Begin:changed by zhaobaoxing for 10G sfp+*/
                                /*link_type = "MAC_LINK_TYPE_PHY";

                                */
                                /*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@17 {
                                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{
                        endpoint1 = "dpni@0";
                        endpoint2 = "dpmac@3";
                };

                connection@2{
                        endpoint1 = "dpni@1";
                        endpoint2 = "dpmac@4";
                };

                connection@3{
                        endpoint1 = "dpni@2";
                        endpoint2 = "dpmac@5";
                };

                connection@4{
                        endpoint1 = "dpni@3";
                        endpoint2 = "dpmac@6";
                };

                connection@5{
                        endpoint1 = "dpni@4";
                        endpoint2 = "dpmac@7";
                };

                connection@6{
                        endpoint1 = "dpni@5";
                        endpoint2 = "dpmac@8";
                };

                connection@7{
                        endpoint1 = "dpni@6";
                        endpoint2 = "dpmac@9";
                };

                connection@8{
                        endpoint1 = "dpni@7";
                        endpoint2 = "dpmac@10";
                };

                connection@9{
                        endpoint1 = "dpni@8";
                        endpoint2 = "dpmac@11";
                };

                connection@10{
                        endpoint1 = "dpni@9";
                        endpoint2 = "dpmac@12";
                };

                connection@11{
                        endpoint1 = "dpni@10";
                        endpoint2 = "dpmac@17";
                };

                connection@12{
                        endpoint1 = "dpni@11";
                        endpoint2 = "dpmac@18";
                };
        };

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;
};

五、RTC调试

修改文件：fsl-lx2160a-rdb.dts
修改内容：增加
rtc: rtc@51 {
compatible = “nxp,pcf8563”;
reg = <0x51>;
#clock-cells = <0>;
};
