Me again ... sorry to ask such a basic question, but I can't get your

Do I use the wrong command?
Better to use git:// url:
git clone git://git.linuxtv.org/mchehab/experimental.git/
I was able to download and compile the code. I installed the kernel and
tried to boot; unfortunately it hangs with the message "Loading initial
ramdisk ..." - after I start the old kernel I check kern.log and syslog
- but I do not see entries from the failed boot attempt. I'll read into
the topic and try around. This will take some time ... so there will be
a dealy, but it's not that I do not care or lacking interest, I just
first have to sort this out.
Well, try to build it first without the atomisp driver. This would allow
you to see what's going on.
I was able to solve the problem I had with the ramdisk - I had to
strip the kernel modules, probably the ramdisk file was too big.
It is possible to boot with the atomisp driver, but I can not see the
camera yet - but maybe that's due to missing firmware, as there were
warnings when I installed the kernel that firmware files are missing.
The following I found in dmesg:
[ 9.331011] kernel: atomisp_ov2680: module is from the staging
directory, the quality is unknown, you have been warned.

The first signs of live :-) ... I'll try to find the firmware files to
see if it makes a difference.
May be of interest as well:
