I have a new Raspberry Pi v2 unit and I'm trying to use an SD card image from one of my other Raspberry Pi B+ units. When I insert the Pi B+ card into the Pi v2 I get a multicolored image on my monitor, but then nothing.
I have read several posts about converting from B+ to v2, but none seem to address in any detail what I should do when the B+ SD card does not boot up. One post (indented below) indicated that I should look at the kernel. Sorry but I'm too much of a beginner to full understand what that meant and what I should be doing :-(
However, be sure to make it clear that you have checked for the correct kernel and include the kernel= line from /boot/config.txt, if any.
Repeating myself, when I put in the old Pi B+ SD card into the Pi v2 I get the multicolored screen and then nothing, the red LED in on solid and the other one is off.
edit: 19 July Additional info: The SD card I'm working with was built up from a NOOBS when I bought my first two Raspberry Pi B+ units in July 2014. When I look at that SD card on my Windows PC I do not see a config.txt, nor a kernel.img file. Should I create a config.txt file? Where can I get a copy of the kernel17.img specified in the above reference?
If I insert a NOOBS SD it boots up ok, but I would really like to not have to totally reconfigure this new unit.
Thanks for any help....RDK
