Booting linux in sd card::how to pass the values to linux program from fpga
hi,
i wanted to pass the values from a design which is running in fpga.. to hps through Linux loaded on sd card.
right now i am doing it using jtag cable+nios2. but i wanted to do it through linux running on the sd card. i got a helloworld demo program which runs using linux(from an sd card)..
but my problem is how will i pass the values to the c program from the fpga.....how to connect both...
in previously i done it with jtag bridge from qsys(iord and iowr instructions).. but here how can i do it...if anybody got any demo or any tips will be very usefull for me..
i dont have any idea how to do it...any help is really appreciated
thanks and regards
