w1302-HD NAND boot

w1302 hd boot u-boot install

开发阶段

NAND Flash Boot 设置

• 作为参考，列出 SD 卡启动模式下的启动参数。

  • 文档提供测试用：

    setenv bootcmd 'if mmc rescan 0; then if run loadbootscript; then run bootscript; else echo In case ENV on MMC/SD is required; echo Please put a valid script named boot.scr on the card; echo Refer to the User Guide on how to generate the image; fi; else echo Please set bootargs and bootcmd before booting the kernel; echo If that has already been done please ignore this message; fi'
    setenv bootargs 'console=ttyO0,115200n8 rootwait rw earlyprintk loglevel=5 mem=364M@0x80000000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 root=/dev/mmcblk0p2 rootfstype=ext3 ip=off'

  • 生产时用：

    setenv bootcmd 'mmc rescan 0;fatload mmc 0 0x82000000 uImage;bootm 0x82000000'
    setenv bootargs 'console=ttyO0,115200n8 rootwait rw earlyprintk loglevel=5 mem=364M@0x80000000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 root=/dev/mmcblk0p2 rootfstype=ext3 ip=off'

• 设置 uboot 参数

  在 uboot 提示符 TI8168EVM# _ 下输入：

  setenv ipaddr 192.168.2.233
  setenv serverip 192.168.2.55
  setenv bootargs '=== delayed ==='
  setenv dollar '$'
  setenv setbootargs 'setenv bootargs "setenv bootargs \\"${dollar}{staticargs} ${dollar}{${bootmsg}args} ${dollar}{${bootfrom}bootargs}\\""; run bootargs'
  setenv bootcmd 'run setbootargs; printenv bootargs; nand read 82000000 280000 440000; bootm 82000000'
  setenv quietargs 'loglevel=4'
  setenv verboseargs 'earlyprintk loglevel=8'
  setenv staticargs 'console=ttyO0,115200n8 mem=439M@0x80000000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000'
  setenv nfsbootargs "root=/dev/nfs nfsroot=${serverip}:/srv/rootfs/w1302-testing-hd,nolock rw ip=${ipaddr}:${serverip}:192.168.2.10:255.255.252.0:TI8168:eth0:off"
  setenv burnbootargs "root=/dev/nfs nfsroot=${serverip}:/srv/rootfs/w1302-product-hd,nolock rw ip=${ipaddr}:${serverip}:192.168.2.10:255.255.252.0:TI8168:eth0:off"
  setenv nandbootargs 'root=/dev/mtdblock7 rw rootfstype=jffs2'
  setenv bootfrom nand
  setenv bootmsg quiet
  saveenv

  上面最后两行参数可做如下配置：

  uboot 变量	可用值
  	ab
  bootmsg	quiet, verbose (earlyprintk loglevel=8)
  bootfrom	nand nfs (192.168.2.55:/srv/rootfs/w1302-testing) burn (192.168.2.55:/srv/rootfs/w1302-product-hd)

• 将 rootfs image 烧写到 flash 中去

  需要 setenv bootfrom burn

  ./install-rootfs stage-02.tar.gz
