I am supposed to send/receive data from xilinx spartan 6 to PC (this is atom processor running on Ubuntu embedded edition[UME]) through a PCIe port. I am currently struck as the basic hello world given in ldd3 doesnt compile in UME after I create the Makefile and run..It comes up with can't find file errors in /usr/block/Kconfig.iosched.. when i compare the source kernel files and the kernel files present in the UME, i find there are more files missing. But the UME loads the ubuntu interface properly. The UME has linux kernel version 2.6.22-menlow-default. I could find the missing files in my PC ubuntu .. I am booting the linux using an USB in the UME.. Since i can connect to internet from the UME device, can i download the latest kernel using apt-get directly..?? will the changes get installed in USB itself?
Basically i am new to linux..kindly help me..
