applo - Burn Image

原先若是空Image可以通过uart boot下载u-boot到ddr中运行，可参考" ymodem under ubuntu "
接下是u-boot启动后，通过tftp下载Image通过nor write写入。

(1) Copy vmlinux.bin, rootfs.arm.jffs2 and appfs.jffs2 to /tftpboot.
   You can get images from /target/output/flash_bin/systems/xxxxxx/
(2) Reboot IRD. If you see "Hit any key to stop autoboot: " at serial port, please press any key.
 
(3) Commands at Uboot.
We need to set the following before flashing all images(uldr.bin,u-boot.bin,vmlinux,rootfs and appfs)
Apollo # setenv serverip <serverip addr>
Apollo # dhcp
Apollo # saveenv
 
Flash uldr(do this only you are upgrading the image from Beta4 to beta5)
#nor erase 0x0 0x100000
#tftp uldr_padded_64k.bin
#nor write 0x0 0x100000
 
Flash uboot(do this only you are upgrading the image from Beta4 to beta5)
#nor erase 0x100000 0x80000
#tftp u-boot_padded_512k.bin
#nor write 0x100000 0x80000
 
Flash vmlinux:
Apollo #  tftp vmlinux.bin
Apollo #  nor write kernel     (OR nor write 0x8000 0x180000 0x500000)
 
Flash rootfs:
Apollo #  tftp rootfs.arm.jffs2
Apollo #  nor write rootfs     ( OR nor write 0x8000 0x700000 0x2000000) (This will take approx 8-10 mins)
 
Flash appfs:
Apollo #  tftp appfs.jffs2
Apollo #  nor write appfs     ( OR nor write 0x8000 0x2700000 0x2000000) (This will take approx 8-10 mins) 
 

4. 设置启动参数如下

setenv norboot "nor read 0x180000 0x500000; go 0x8000"

setenv bootcmd "run norboot;"

setenv bootargs "noinitrd ip=dhcp console=ttyS1,115200n8 mtdparts=nx_2016:1536k@0k(boot),5m@1536k(kernel),32m@7m(root),32m@39m(appfs),-(extra) root=/dev/mtdblock2 rw rootfstype=jffs2"

或者setenv bootargs "noinitrd ip=dhcp console=ttyS1,115200n8 ${mtdparts} root=/dev/mtdblock2 rw rootfstype=jffs2"

引用${mtdparts}更可靠，但必须是双引号而不是单引号才能展开

 否则总是产生类如下的错误：
