openmoko - flash kernel and rootfs

安裝 usb 連線軟體： dfu-util。
Debian 直接用 apt 安裝就可以。

通常需要

1. kernel - uImage
2. rootfs

bootloader 不一定要重燒

rootfs 通常是有 jffs2 在檔名中，kernel 通常就有 uImage 在檔名中。

開機進入 nor boot (nand boot) ? 就可以接上 usb ，和 dfu-util 溝通。

按著hold key 開機，進入nor boot 畫面，插上 usb。dmesg..

所以應該是有偵測到...

燒錄過程要注意的是...沒有操作30 sec 後，機器會自動 power off。
所以看到螢幕黑掉，就要重新 power on.

rootfs download 比較久。

重開機很花時間，約需要 2 min，約 1min 後才會出現splash screen.然後滅掉..
