need to install linux kernek 3.15 on friendlyARM 6410

iam working in embedded devices and trying to install linux kernel 3.15 on
the device friendlyARM 6410 . but there are a lot of diffrences between the
default kernel (2.6.38) and target kernel .

I could give you a few hints, but they will probably require a fair bit of
work.
 
Why do you need 3.15?

for ssd support

Hmmm.  In the 3.15 mainline is there any config files for the mini6410. 
Think so, but most likely need patching.

There is a Pengutronix BSP for the 6410, but I doubt the kernel version is
beyond 3.7 or 3.11  Have a look.

i tried its not working , do u have alternate an alternate solution???

LENINLAL, how did you connect your SSD to the Mini6410/Tiny6410?

usb cable

Then I guess it is a "USB mass storage device" from the Mini6410/Tiny6410
point of view (like a memory stick). Just enable the support for such kind
of USB device in the kernel and it should work.
