小米路由器mini（Xiaomi mini R1CM）刷Openwrt

scp /path/to/PandoraBox-xxxx.bin [email protected]:/tmp/PandoraBox.bin
mtd -r write /tmp/PandoraBox.bin firmware

從爬文中得知，小米路由器Mini 官方韌體是雙系統，由於 ROM 有16MB，官方韌體都小於8MB，所以會有一份備援系統（8MB+8MB），因此如果刷了大於 8MB 的第三方韌體的話，會覆蓋掉第二個分區的系統，導致未來刷回官方韌體時會有掉 SN 的問題，而且再也無法刷入 SSH，從此以後就只能乖乖用官方韌體，再也不能玩刷機，目前新版的 PandoraBox 韌體大約都在 10MB 左右，所以刷機還真要有點決心，除非完整備份小米路由器Mini 中所有分區的資料，才能在日後完整刷回官方韌體，當然，如果已經完全放棄官方韌體的話，這些問題都是不用考慮的。from - http://blog.icece.tw/MiWiFi-Mini-Flash-uboot

xinput set-button-map 21 1 0 3

Explaination

The first number is the id of the pointer (you'll often only have one, in this case there were two, 9 and 10).

The next numbers are what you do with the first, second, and third (ie, left, middle, right) mouse buttons. The "1 0 3" tells it that the left button should do a left click (action 1), the middle button should do nothing, and the right button should do a right click (action 3). If you want to make the middle button also do a left click you could use "1 1 3". If you wanted to switch the right and left actions you could use "3 0 1".
