I think that is cortex only, not ARM9 (correct me if I'm wrong).<div><br></div><div>I've built a working Erlang for a cortex-a8 before using vanilla sources; no special port was required. I only tested it very briefly, but it seemed to work well. I can't think of any reason why it wouldn't also work on an ARM9. I built it from a Gentoo stage3 chroot on the target platform. Browsing the gentoo mirrors, I see that stage3 tarballs are available for armv4, v5 (ARM926), v6, and v7(cortex).</div>
<div><br></div><div>I have also run Erlang on a 100MHz x86. It was quite slow to start, but once up and running it was fine. I suspect the slowness was due more to filesystem and io problems than Erlang itself. Just wanted to give this datapoint because I know ARM9 devices operate in the low 100's of MHz.</div>

<div dir="ltr"><div> If so, the usage scenario will be many processes running on a single node, with frequent message-passing, some access to binary files, and no shared data (no ETS, DETS or Mnesia). Is this scenario likely to perform well on an embedded Erlang?</div>
