[uClinux-dev] userspace and kernel space

[Muthu, Pushparaj IN GGN SISL]

Question related to  uClinux  has user space and kernel spaceser space .

My question is
In uClinux when user space calls system call , it invokes software interrupt and enter into kernel space serve the routine and come back to user space like destop linux. or user call like wrapper function over the  kernel call.

Some confustion .
