I’m attempting to get SPI up and running by playing with the device tree files. I’ve gotten the drivers and device tree files to compile, however I’m having trouble when attempting to build and flash the
I get the output:
Warning: root device does not exist.
Press Ctrl-C to abort build, or Enter to continue
Pressing enter, the program says
executing /etc/postinst.d/zz-flash-kernel 3.10.0 /boot/vmlinuz-3.10.0
Ignoring old or unknown version 3.10.0 (latest is 3.13.0-71-generic-old)
When I look into the boot folder, it looks like the new images were created, but probably not getting used as I changed the spi device name being built so theoretically the new device should show up.
Running “make modules_install” installs a couple modules, but certainly not all of the modules present in the old kernel.
Am I missing a step somewhere? I’m admittedly fairly new to building Linux, and definitely new to device tree overlays. Hopefully, someone can point me in the right direction!
