Hi,<div><br></div><div>Thanks for you help, but I'm not sure if I'm doing something wrong. I pulled the new version today and I continue getting the same error:</div><div><br></div><div><div>kernel PANIC! kernel assertion "limit > start" failed at ../../bf/kernel/arch/arm/phys_mmap.c:130</div>
<div><br></div><div>Gem5 has been checked out on the specified version and patched accordingly. Would it be possible to get the specific revision on which Barrelfish ARMv7 was booting on Gem5?</div><div><br></div><div>Many thanks!</div>

Hi Zeus,<br><br> I don’t know if it will help you, but you will find attached a chapter of our internal GEM5 tutorial (thanks Samuel for the help!) where I explain (some steps) how to use GEM5 with Barrelfish.<br><br>
As Samuel said, this is an old version and he will launch a public release soon, but maybe this version <span lang="en"><span>is</span> OK<span> for what</span> <span>you want to do</span><span>.</span></span><br>

</div>As you 've probably seen already, we did make a public release, and as<br>
Samuel suggested, you should be able to find gem5_patches.patch in the<br>
current tree. I am not sure if gem5 on ARM works without problems for the<br>
current tip, but if there are problems they should be relatively easy to<br>
fix.<br>
<br>
