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 

-h, –help	ls-debug help information
-ts, –timestamp=X	Enable/Disable timestamp printing, X is ON or OFF
-c, –console=X	Enable/Disable printing in UART console, X is ON or OFF
-l, –log=X	Enable/Disable printing in DDR log, X is ON or OF
-u, –uart=X	Set UART ID of the console, X = [0 – 4], 0 = OFF
-ll, –level=X	Set logging level, X = [0 – 5]0: Global1: Debug2: Info3: Warning4: Error5: Critical
-m, mem, –memory	Dump information about memory modules available
dpxy.z	Dump information about MC respective object

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";

                                */
                                /*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+*/

                                */
                                /*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>;
};

一、启动分析

uboot启动后会通过检测lx2160ardb_boot.scr配置文件，实现默认启动引导。此系列芯片引导方式一样。

打开./configs/board/lx2160ardb_rev2/manifest文件分析

vim ./configs/board/lx2160ardb_rev2/manifest

distroboot=\
'env exists dtb || setenv dtb fsl-lx2160a-rdb.dtb;'\
'env exists kernel_image || setenv kernel_image Image;'\
'env exists devpart_boot || setenv devpart_boot 2;'\
'env exists devpart_root || setenv devpart_root 4;'\
'part uuid $devtype $devnum:$devpart_root partuuidr;'\
'setenv bootargs console=ttyAMA0,115200 earlycon=pl011,mmio32,0x21c0000 root=PARTUUID=$partuuidr rw rootwait pci=pcie_bus_perf $othbootargs;'\
'load $devtype $devnum:$devpart_boot $kernel_addr_r $kernel_image;'\
'load $devtype $devnum:$devpart_boot $fdt_addr_r $dtb;'\
'env exists secureboot && echo validating secureboot && run secureboot_validate;'\
'booti $kernel_addr_r - $fdt_addr_r'


distroboot_ima=\
'env exists dtb || setenv dtb fsl-lx2160a-rdb.dtb;'\
'env exists kernel_image || setenv kernel_image Image;'\
'env exists devpart_boot || setenv devpart_boot 2;'\
'env exists devpart_root || setenv devpart_root 4;'\
'part uuid $devtype $devnum:$devpart_root partuuidr;'\
'load $devtype $devnum:$devpart_boot $kernel_addr_r $kernel_image;'\
'load $devtype $devnum:$devpart_boot $fdt_addr_r $dtb;'\
'setenv initramfs_addr_r 0xb0000000; setenv initramfsheader_addr_r 0x80300000;'\
'load $devtype $devnum:$devpart_boot $initramfs_addr_r initramfs.img;'\
'env exists secureboot && echo validating secureboot && run secureboot_validate;'\
'setenv bootargs console=ttyAMA0,115200 earlycon=pl011,mmio32,0x21c0000 root=PARTUUID=$partuuidr rw rootwait pci=pcie_bus_perf $othbootargs;'\
'booti $kernel_addr_r $initramfs_addr_r $fdt_addr_r'

通过分析配置文件，发现Linux和rootfs的引导取决于devpart_boot和devpart_root两个变量，所以通过修改这两个变量值，便可动态实现，分区引导切换。

二、手动引导切换

进入uboot命令行

setenv devpart_boot  2
setenv devpart_root  4
saveenv

2和4代表分区号

三、动态引导切换

如实现动态引导切换需要通过fw_env工具实现。请参照《fw-env开启文件系统设置uboot环境变量》http://www.recologypower.com:9080/?p=1247

四、分区处理

flex-installer -i pf -p 6P=200M:1536M:128M:13G:1536M:-1 -d /dev/sdx

五、烧录程序

1、进入uboot修改源码

vim include/configs/lx2160a_common.h

最后增加

/*Begin:add by zhaobaoxing for env*/
#define CONFIG_SYS_MMC_ENV_DEV          0
#define CONFIG_ENV_SIZE                 0x2000          /* 8KB */
#define CONFIG_ENV_SECT_SIZE            0x20000
#define CONFIG_ENV_OFFSET               0x500000
#define CONFIG_ENV_ADDR                 (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET)
/*End:add by zhaobaoxing for env*/

2、修改fw_env.config文件

# Configuration file for fw_(printenv/setenv) utility.
# Up to two entries are valid, in this case the redundant
# environment sector is assumed present.
# Notice, that the "Number of sectors" is not required on NOR and SPI-dataflash.
# Futhermore, if the Flash sector size is omitted, this value is assumed to
# be the same as the Environment size, which is valid for NOR and SPI-dataflash
# Device offset must be prefixed with 0x to be parsed as a hexadecimal value.

# NOR example
# MTD device name       Device offset   Env. size       Flash sector size       Number of sectors
#/dev/mtd1              0x0000          0x4000          0x4000
#/dev/mtd2              0x0000          0x4000          0x4000

# MTD SPI-dataflash example

1、下载安装

https://www.nxp.com/design/software/development-software/codewarrior-development-tools/codewarrior-network-applications:CW_SUITES_NETAPPS

1、基于nxp板卡dpdk配置测试

由于NXP为LX2160增加了硬件加密引擎与openssl接口，我们可以直接编译使用openssl API接口。

1、编译：

$ cd flexbuild
$ source setup.env
Build cryptodev-linux:
$ flex-builder -c cryptodev_linux -a arm64 # automatically setup cross-toolchain and fetch 
cryptodev-linux repository to build
Build OpenSSL:
$ flex-builder -c openssl -a arm64
Merge OpenSSL and cryptodev-linux components into target rootfs:
$ flex-builder -i merge-component -a arm64
Generate bootpartition tarball:
$ flex-builder -i mkbootpartition -a arm64
   flex-builder -i mkbootpartition -a arm64 -m lx2160ardb_rev2 -b sd

2、配置：

cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
修改为：
#include /etc/ld.so.conf.d/*.conf
# libc default configuration
/usr/local/lib
# Multiarch support
/usr/local/lib/aarch64-linux-gnu
/lib/aarch64-linux-gnu
/usr/lib/aarch64-linux-gnu
/usr/lib/aarch64-linux-gnu/libfakeroot

3、加载模块

user@localhost:~$ sudo modprobe cryptodev
[sudo] password for user:

user@localhost:~$ ls /dev/crypto
/dev/crypto

user@localhost:~$ openssl engine
(devcrypto) /dev/crypto engine
(dynamic) Dynamic engine loading support

4、Verify the CAAM offloading

Hardware operations can be monitored with the interrupt counters for CAAM JR and QI (DPAA1 and DPAA2) interfaces.

user@localhost:~$ cat /proc/interrupts | grep jr
78: 20 0 0 0 GICv2 103 Level 1710000.jr
79: 0 0 0 0 GICv2 104 Level 1720000.jr
80: 0 0 0 0 GICv2 105 Level fsl-jr0

user@localhost:~$ openssl enc -aes-256-cfb -k secret -P -md sha1
*** WARNING : deprecated key derivation used.
Using -iter or -pbkdf2 would be better.
salt=233157F098D1B0E8

iv =A4E2C86E0DBA1211B5A4B02EBEFF6DC4

user@localhost:~$ cat /proc/interrupts | grep jr
78: 54 0 0 0 GICv2 103 Level 1710000.jr
79: 69 0 0 0 GICv2 104 Level 1720000.jr
80: 0 0 0 0 GICv2 105 Level fsl-jr0
