Ironically, I've just spent nearly a day trying to get the GDB/Armulator or GDB/Skyeye (ARM) configurations of latest uClinux-dist to boot on Skyeye, following the straightfoward instructions which are posted on various wikis (which presumably must have worked at the time), and it half boots but doesn't reach a login prompt yet. Lots of Skyeye messages about accesses outside the valid address space. I'm using exactly the two toolchains mentioned in the uClinux-dist source, arm-linux-tools-20061213 and arm-linux-tools-20070808, with executable names matching what uClinux-dist looks for, so there isn't a toolchain mismatch. (My first attempt, with uclinux-tools-20050221 GCC-3.4.3 from develer.com which I've been using for a lot of arm-nommu work, could not compile even a single executable in the latest uClinux-dist, due to it's uClibc source making toolchain-specific assumptions). These aren't things I expect you to solve for me, but as a result I found a few small kernel Kconfig bugs and uClibc bugs, whose fixes I should feed back to the right places. > Catalin Marinas (from ARM) got the last of required core changes > commited to Linus' tree for 2.6.32 - so all the core parts are > now there for non-MMU ARM.

I'm slowly getting around to adding an arm-nommu real target which is not supported at all in existing mainline or uClinux-dist kernels, so that'll be a good way to find out.
