Hello Dave ,
Can you please tell me which is the machanism of writing new code in
the FPGA (I'm talking about the Lattice XP2 from the 7390 TPC ). As
far as i know this chip contains the code for VGA , SD and a couple
of serial ports.
1. Can i copy the actual contents of the chip for future restauration?
2. If i make a new code , for using the new functionality i think i
have to write a device driver that will communicate with the new
function of the Lattice.??
3. Please explan me a bit how this interaction between linux and
Lattice is done from your point of view.
My intention is to take an example from opencores and use it for
learning.
With respect ,
Eugen Dodiu
