Hi!
In u-boot 2015.04-rc, as soon as execution hits printf("%d"), it hangs. (Usually, that's after "DRAM: " message).
printf("%d") expects an argument, so could it be that it touches random piece of memory and thus hangs?
It had an argument, sorry for confusion. I was actually doing this: the test with %s works, the one with %d kills it.
I suspect too small stack...?
