CCAV:

On some old devices such as Mercury MW4530R v1, it's CPU is AR9344.
There is no FPU in this cpu.
So the official firmware can not run golang programs.
Please default enbale Kernel -> MIPS FPU Emulator option when building official firmwares.
This helps the people who have no ability to build a custom firmware.

Hi, Damn, very likely this will not be enabled by default in the near future until 4MB flash device are finally faded out. However, in recent release of go1.10, there is now already softfloat support for mips32 arch. Please give it a try and see if it works your situation.

To quote go1.0 release notice here (https://golang.org/doc/go1.10)

On 32-bit MIPS systems, the new environment variable settings GOMIPS=hardfloat (the default) and GOMIPS=softfloat select whether to use hardware instructions or software emulation for floating-point computations.
