大家好，最近在看Appro的参考设计的时候，没看到以往的“insmod cmemk.ko”这样的脚本，我用的是4.0的RDK
在/etc/init.d/rcS脚本文件里368相关的加载脚本如下： DVEVMDIR=/opt/ipnc # Load the dsplink and cmem kernel modules /bin/mount -t sysfs none /sys -n mount -t debugfs none /sys/kernel/debug cd $DVEVMDIR mount -t jffs2 /dev/mtdblock4 /mnt/nand ./system_server & $DVEVMDIR/beforeloadkmodule.sh $DVEVMDIR/loadkmodules.sh $DVEVMDIR/loadmodules_ipnc.sh ifconfig lo 127.0.0.1 cd $DVEVMDIR ./boot_proc 1 $DVEVMDIR/autorun.sh mount devpts /dev/pts -t devpts 我查看了Appro参考设计里所有368有关的*.sh，比如上面提到的“beforeloadkmodule.sh”、“loadkmodules.sh”、“loadmodules_ipnc.sh”等等，都没有看到“insmod cmemk.ko”这样的语句。 希望ti的专家们帮我解释一下这个现象。 还是我没找到？还请专家告诉我在哪找到？

我也遇到了相似的问题 我用的是dm365 原先SDK用的是dvsdk_dm365_4_02_00_06， 是需要手动insmod cmemk.ko的 后来SDK换成了ipnc_psp_03_21_00_04，发现内核直接都加载了 但是lsmod看一下 发现 也没加载上；现在想把cmemk.ko从内核中剥离出来， 还没找到方法
