拔出記憶卡,放到其他台電腦裡,修改第一個分割區裡的cmdline.txt,裡頭只有一行,原本內容大概如下: | |
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait | |
在最後面加上「init=/bin/sh」。 | |
然後放回Raspberry Pi開機,應該很快就會出現「#」提示字元,然後輸入底下的指令: | |
# su (變成超級使用者) | |
# passwd pi (重新設定帳號pi的密碼) | |
# sync (清空緩衝區,確保設定儲存生效) | |
# exec /sbin/init (執行一般開機後會執行的程序) | |
出现Authentication token manipulation error错误 | |
OOOOOOOKAY i just fixed this my self: | |
After you type "init=/bin/sh" into cmdline.txt in the recovery boot up, and your RasPi has booted up, you | |
should be on the cmd line. BEFORE you type "passwd pi" , type | |
mount -rw -o remount / | |
then try changing the password. |
