3、查看DDR大小和频率

支持DDR3，1GB，最高频率792MHz
启动时会有日志打印
如：

[230]DRAM CLK = 792 MHz
[232]DRAM Type = 3 (2:DDR2,3:DDR3)
[235]DRAMC ZQ value: 0x7b7bfb
[238]DRAM ODT value: 0x42.
[241]ddr_efuse_type: 0x0
[244]DRAM SIZE =1024 M

4、查看当前内核版本

根目录执行：

ubus call system board

结果如下：

root@TinaLinux:/# ubus call system board
{
        "kernel": "5.4.61",
        "hostname": "TinaLinux",
        "model": "sun20iw1p1",
        "release": {
                "distribution": "tina.kunyao.20211213.091259",
                "version": "Neptune",
                "revision": "5C1C9C53",
                "target": "d1-nezha\/generic v3.5",
                "description": "tina.kunyao.20211213.091259 4.0.0"
        }
}

5、查看当前uboot版本

上电可以看到log打印：

U-Boot 2018.05-00088-g778d823e36 

或执行命令：

cat /proc/cmdline 

如下

root@TinaLinux:/# cat /proc/cmdline
ubi.mtd=sys ubi.block=0,rootfs earlyprintk=sunxi-uart,0x02500000 clk_ignore_unused initcall_debug=0 console=ttyS0,115200 loglevel=8 root=/dev/ubiblock0_5 rootfstype=squashfs init=/sbin/init partitions=mbr@ubi0_0:boot-resource@ubi0_1:env@ubi0_2:env-redund@ubi0_3:boot@ubi0_4:rootfs@ubi0_5:dsp0@ubi0_6:recovery@ubi0_7:UDISK@ubi0_8: cma=8M snum= mac_addr= wifi_mac= bt_mac= specialstr= gpt=1 androidboot.hardware=sun20iw1p1 boot_type=5 androidboot.boot_type=5 gpt=1 uboot_message=2018.05-00026-g53b07c0278(12/10/20

6、查看当前Tina系统版本

ubus call system board

结果如下：

root@TinaLinux:/# ubus call system board
{
        "kernel": "5.4.61",
        "hostname": "TinaLinux",
        "model": "sun20iw1p1",
        "release": {
                "distribution": "tina.kunyao.20211213.091259",
                "version": "Neptune",
                "revision": "5C1C9C53",
                "target": "d1-nezha\/generic v3.5",
                "description": "tina.kunyao.20211213.091259 4.0.0"
