Hi brian and thanks for the link, I've been there the problem is all the download links are now dead so it's not possible to follow those inst.
On the other hand I'm already running debian jessie on it but as you know it's a lot slower and prone to SD failure as I have a lot of power failures.
I build lede from this guys repo: https://github.com/nwf/lede
He has added the pogo v4 and builds all kinds of images but they all fail with the: starting kernel freeze problem.
I also build openwrt CC which boots the kernel well but it fails to find the rootfs on mmcblk0p1 which is there formatted as ext3, this is the error.
VFS: Cannot open root device "mmcblk0p1" or unknown-block(0,0): error -6
So I guess I'm out of luck
Luis
