For those who wants to try out developing for MIPS64, this board looks interesting which is originally a router but might be interesting for those who design operating systems. The board is rather cheap and can be booted from a USB stick and comes with both BSD and Linux support. However, the question remains who suitable this board is for bare bone development. Copying your binaries to a USB stick all the time is tiresome, so the question is if there is a possibility to setup an image on the PC, connect the board to PC and boot it from there.

Anyone that has experience with this board on this forum?

I didn't try this exact board but most MIPS board have either RedBoot or U-Boot, so you can connect PC and board via serial port (oh, please, don't tell me that you PC doesn't have serial ports) and use something like xmodem protocol (or even TFTP/HTTP via ethernet) to transfer kernel and execute it.
JTAG is also an option but it's not a simple way.

Did you try non-x86 boards before? Looking for serial port becomes almost an instinct when you have such experience.

I think there are USB to serial converter in the worse case scenario where you, like me, have no serial ports (I have never used one myself so I am not sure if it even works).
