I have to admit to being incredibly frustrated that my Edison would not boot a stock kernel; Intel's Edison patches are apparently a must. Fine, but the Edison patches branched off of kernel 3.10.17, which expired back with the dinosaurs.
I've got a github repo up based on Yocto 3.10's kernel version 3.10.65, with Intel Edison patches merged in, and it seems to work well: https://github.com/esialb/yocto-3.10-edison https://github.com/esialb/yocto-3.10-edison
I've been building new kernels by cross-compiling them on my desktop, and using dfu-util to load new firmware on the Edison with the new kernel. The github repo includes a script that modifies the disk images in an Edison dfu-util toFlash/ directory to install a kernel you have just built. Example:
$ git clone https://github.com/esialb/yocto-3.10-edison.git https://github.com/esialb/yocto-3.10-edison.git
$ cd yocto-3.10-edison
$ make xconfig
$ sudo ./EDISON/dfu-image-install.sh ../../ubilinux-robin-kernel/toFlash/ [sudo] password for robin: mounting filesystem images copying kernel modules copying kernel image unmounting filesystem images
$ cd ../../ubilinux-robin-kernel/toFlash/
$ sudo ./flashall.sh
The image updater script needs to run sudo root, because it has to mount to filesystem images to modify them, but flashall.sh runs as root anyway.
I've also included a patch that fixes the kernel panic caused on 3.10.17 whenever a bluetooth rfcomm connection is closed, so I can run a login window on a bluetooth serial port now.
Anyway, I'm hoping people will find this useful, maybe even give suggestions. It was worth it for me to do just for myself.
