We have very good Qemu defconfigs in Buildroot, for all of mips, mipsel, mips64el and mips64: $ ls -1 configs/qemu_mips* configs/qemu_mips64el_malta_defconfig configs/qemu_mips64_malta_defconfig configs/qemu_mipsel_malta_defconfig configs/qemu_mips_malta_defconfig These allow to very easily test things on those architectures even when hardware is not available. Note that I'm not saying that you *have* to test Erlang on all those architectures, I'm perfectly fine with enabling it on mipsel today, and enabling it later on other architectures when people need that. I just wanted to take this opportunity to mention the Qemu defconfigs, that are very regularly maintained and updated by Gustavo. Best regards, Thomas

I have found the qemu configs to be really useful in verifying that projects build and for simple testing. My stumbling block has been that many of the interesting things that I want to try out with Erlang require it to act like a server. For that to work, I would need to start qemu so that it has its own IP address and that Erlang can bind to an externally visible port. I know that this is possible, but I've struggled with the qemu docs enough that I've always gone to real hardware for testing. I realize that this is now completely off topic, but if someone knows of a step-by-step way of setting this up for a BR qemu config, I'd try again. (Yes - I've seen the Arch wiki qemu docs) Best regards, Frank

Erlang works fine on mipsel platforms so add it to the supported list.
