我觉得是名字重了，之后改成tiny6410_adc_1，重新做个tiny6410_adc_1.ko模块，我重新利用友善的2.6.38源码做了一个zImage，在make menuconfig 的选择时候没有选以前的adc，也就是没有吧adc编译进内核zImage，吧这个zImage烧到了板子上，ls /dev 下面你的却没有adc（以前有）。然后我就之前pc机的2.6.38源码树里面做了的那个tiny6410_adc_1.ko的驱动模块，通过nfs挂载到开发板上，cp到/lib/modules/2.6.38-FriendlyARM目录下面，然后insmode tiny6410_adc_1.ko，出现下面的错误。 [root@FriendlyARM 2.6.38-FriendlyARM]# insmod tiny6410_adc_1.ko tiny6410_adc_1: Unknown symbol mini6410_adc_release_io (err 0) tiny6410_adc_1: Unknown symbol mini6410_adc_acquire_io (err 0) insmod: can't insert 'tiny6410_adc_1.ko': unknown symbol in module or invalid pa rameter 请指教............................
