各位大大好
小弟是Linux 新手
步驟都是照書做 且修改過CC的路徑 試過insmod hello.ko 電腦可以DNW正常show出文字
以下是我將範例的 led.ko 檔加到開發板上的情形
#
# cd sdcard
# ls
LOST.DIR
DCIM
launchpad.apk
apkInstaller.apk
MediaPlayer.apk
koo_6.apk
Big Planet TW 1[1].2.4.apk

u-boot_mmc.bin
test.ko
RMaps
bk_light.ko
dc_motor.ko
led.ko
BigPlanet_maps.sqlitedb
BigPlanetTracks
pwm.ko
# lsmod
led 2912 0 - Live 0xbf000000
# rmmod led
LED driver release success!
# insmod led.ko

# cat /proc/devices

# mknod /dev/led c 30 0
mknod: not found
#
之後就不知道怎麼照書中的繼續了... 苦惱中
led.ko 的內容 是讓ARM開發板的 兩顆LED交互閃爍
可是我目前還是恆亮的狀態
希望有大大能幫我解惑!!
