Hi, it is quite some time ago since I tried XIP on uClinux/Coldfire, but could not get it to run. I do not recall which exact problem I had, because I was fine without it in the end.
What is it you want to achieve? Is XIP the only possible option? In my case, I was hoping to reduce startup and boot time in general, and I ended up with a different compression scheme for the kernel and rootfs (U-Boot images), because load time from flash and decompression were what really made my system slow. And, even more, flash access time becomes an even more critical factor when using XIP. On the other hand, my system was quite specialized with only one application running being started on boot and only terminated in case of power failure or watchdog reset. ;-) However, this might be a common scenario for many embedded applications. Just asking, because memory is not a cost factor any more in most cases, so maybe focusing on XIP is not the way to go, especially considering flash access being slower than DRAM in most cases anyways.
