Besides the zImage and rootfs the build process outputs an .dtb file. Now, in order to get the FPGA fabric involved, I'd have to come up with a modified dts and build it. That's where I'm a bit lost in the blur. I can not figure out where the generated dtb is coming from? What's the mechanism behind? I cannot find any .dts nor .dtb in the meta-altera layer. Besides that I realized that if I use the dtb that shipped with the board with the "daisy" kernel, the boot process gets stuck at "Waiting for root device /dev/mmcblk0p3..." The "shipped" kernel is version 3.8.0 while the "daisy" one is 3.10.31-ltsi. Was there a change in the device tree layout as the "old" one doesn't work with the "daisy" kernel? Thanks in advance!
