I have modified AD9361/AD9364 HDL and added custom AXI SPI in order to be used with our tunable filters..
and used standalone(sdk) drivers and successfully interacted with our tunnable filters that uses SPI interface..
my next step is interact with AXI SPI core using linux operating system
!I have my design hdf file, what I can do next
!Do I need to modify device driver tree or make a new one!
Do I need to rebuild the linux kernel!
Do I design another linux drivers for AXI SPI I have added!
How can I use ,for example terminal from linux, to read/write to/from AXI SPI core!!
