Well, I am using a custom board with a MX.31 processor, but it is not important. You can use any board running linux with gpio sysfs enabled in kernel to program an external device (if the levels are compatible, of course..) > > Would it work on openwrt routers where some GPIOs are available? It should run, but you cannot use as jtag interface for your router. It is thought to program a device (in my case, a FPGA) whose JTAG interface is connected to some gpio pins of the microprocessor. In your case, you can use it to program something else.
