I originally entered this as a reply to "MAX31855 driver software" but have now re entered under it own title as the MAX31855 thread was rather old and this issue is specific to a more generic problem.
I am trying to initiate spi (because I want to use the MAX31855 driver) but am failing with the command "sudo modprobe spi_bcm2708" . The response I get is: " ERROR: could not insert 'spi_bcm2708': No such device".
I have a Pi2 with a NOOBS sim as supplied new with the hardware. I have been using it satisfactorily for various python programming without problems for a few months. In effort to resolve this problem I have: "sudo apt-get update", "sudo apt-get upgrade", have added dtparam=spi=on to the config.txt. I have checked for a blacklist file in etc/modprobe.d but there is none.
I am now stuck and would very much appreciate ant help with suggestions or pointers.
