I just recently compiled the kernel after cloning it from git.

I followed the steps described here:
https://github.com/parallella/parallella-bin
in the readme.md

After following these step resulted in a hanging boot, don' exactly know where. But the problem appeared to be in the device tree. I think the default headless device tree has no support for serial console, while the build compiler is configured to hav some. I solved it by building another device tree than described. I copied the steps I followed from the link above. The differences I marked bold


How to compile the ADI based linux kernel? (uImage)
git clone https://github.com/parallella/parallella-linux
cd parallella-linux bash
export ARCH=arm
export CROSS_COMPILE= #eg arm-xilinx-linux-gnuabi-
export PATH=:$PATH
make ARCH=arm parallella_defconfig

Try this first, when it works, take the step to hdmi

Hope it helps someone

So I made all the modules compile into the kernel.
Otherwise maybe you haven't updated the DeviceTree?

I use serial console to watch the boot procedure, after u-boot load the image, the console is frozen,
and no output from HDMI.

following image compiled in native-platform
## Booting kernel from Legacy Image at 03000000 ...
Image Name: Linux-3.14.12-parallella
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 4910072 Bytes = 4.7 MiB
Load Address: 00008000
Entry Point: 00008000
Verifying Checksum ... OK
## Flattened Device Tree blob at 02a00000
Booting using the fdt blob at 0x02a00000
Loading Kernel Image ... OK
OK
Loading Device Tree to 1fffa000, end 1ffff19e ... OK

and this is compiled in cross-platform
## Booting kernel from Legacy Image at 03000000 ...
Image Name: Linux-3.14.12-parallella-xilinx-
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 3350744 Bytes = 3.2 MiB
Load Address: 00008000
Entry Point: 00008000
Verifying Checksum ... OK
## Flattened Device Tree blob at 02a00000
Booting using the fdt blob at 0x02a00000
Loading Kernel Image ... OK
OK
Loading Device Tree to 1fffa000, end 1ffff19e ... OK

I use the default config, but the image size is very different, 3.2MB vs 4.7MB, why?
and which repo can work with HDMI?
