We know the yun has a soft spi interface, of which SCLK, MISO and MOSI are AFAIK on the ICSP header.
Its SS is going directly to the avr’s ss.
I want to control an SPI-based shield(infact, a gameduino 1(infact, its olimex clone)) directly from the yun`s linux cpu, instead of the crappy avr mcu(last time i checked, the gameduino examples wouldnt even fit in its flash, also it can’t execute stuff from ram).
As the only other MIPS gpio thats on some form of pin is HANDSHAKE on digital pin 7, i would like to change the spi to use that as SS(its a software one anyways).
Then i would wire the SPI signals from the icsp header to thier usual location, and connect pin 7 to whatever pin the shields SS is(10 i believe).
So how to change the spi driver to use HANDSHAKE as SS?
