Hello,
I just switched from Buildroot 2015.08.1 to 2015.11.1, and tried to keep
the same configuration. SPI was working well, before the switch.
Now, I am having some trouble with the SPI driver, namely spi_bcm2835 :
when I insert the module, there is no log in dmesg output, and nothing
is created in /sys/bus/spi/devices.
I could make it work by loading spi_bcm2708 instead, despite the
deprecated warning. In this case, I get some logging messages and
/sys/bus/spi/devices/spi0.0 and /sys/bus/spi/devices/spi0.1 appear.
Any idea ?
David.
