modprobe: ERROR: could not insert 'spi_bcm2708': No such device

guys any ideas what i did wrong? i can run make, everything compiles, i also restarted, the RFM12b looks connected. no idea what is wrong :(((

If that by accident is a raspberry pi with a new kernel try to enable spi: https://www.raspberrypi.org/documentation/configuration/device-tree.md

I have the same issue :( I enabled the devicetree and SPI thru raspi-config and uncommented the dtparam=spi=on in /boot/config.txt

I re-ran the make command but still get modprobe: ERROR: could not insert 'spi_bcm2708': No such device

P.S. is it normal that the first time I ran make it took over 3 hours to complete?

nxdefiant commented 8 years ago

did you reboot after changing config.txt?

AlbanT commented 8 years ago

Pretty sure I did :) I have been struggling for several days now. First I couldn't get rpi-source to install. Only after changing to an older image file it worked. Now the rfm12b is not working as planned :(

I'll try again, I shut down my RPI after I posted my message so when I try it again now I'm 110% sure I rebooted :)

Nope again: modprobe: ERROR: could not insert 'spi_bcm2708': No such device

nxdefiant commented 8 years ago

then you should ask this on the rpi boards. This is a problem of your rpi, not this module.

AlbanT commented 8 years ago

I think I'll continue the way I was using it before. A Jeenode connected to my RPI thru serial :(
