Gaurang Bhatt (INDIA)
We need to reduce the size of uclinux kernal so that it fits into the 4MB on board flash on BF537 EZ-Kit Lite. We have seen that the kernal image on the stamp board is 3.7MB. We are right now working with the uclinux kernal size of 5.7MB and when we configured it for profiling, the size went up to 7MB.
1) What are the options that have been disabled so that the kernal size is reduced to 3.7MB in stamp board?
2) Is it possible to keep the kernal size under 4MB, even after including the profiling options?
Thanks in advance,

if the image is too big, then remove things you do not need. that is how you shrink the image. read the FAQ for some tips:
if you build everything with the profiling flag, it's going to be much larger. there is no way to avoid that. we really havent done any tests to figure out exact details as everyone's desired setup is different.
the uclinux-dist has all the config files posted so you can compare them yourself.
