You cannot compile the normal Linux enet driver as module because it's not supported. But for RTnet, a module must be loaded to provide the required functionality. Therefore you have to export the missing symbols in ppc_ksym.c: EXPORT_SYMBOL(cpmp); EXPORT_SYMBOL(m8xx_cpm_hostalloc); EXPORT_SYMBOL(m8xx_cpm_dpalloc); EXPORT_SYMBOL(m8xx_cpm_dpfree); ... EXPORT_SYMBOL(consistent_alloc); EXPORT_SYMBOL(consistent_free); And do not forget to disable the "enet" driver in the kernel. The README.rtnet at ftp://ftp.denx.de/pub/RTAI/old/24.1.12/ might be useful, even if it's not up to date. > yes i would like to go higher vesrion , as our project needs to meet > deadline , i need to make many chnages with higher version of kernel , yes > but will take it up after sometime .
