Re-building an existing firmware but add a setting MIPS_FPU_EMULATOR=yes

Hey Guys!

I got an http://downloads.lede-project.org/releases/17.01.2/targets/ramips/mt7621/lede-17.01.2-ramips-mt7621-dir-860l-b1-squashfs-factory.bin firwmare, which is awesome, but I need NodeJS and it needs MIPS_FPU_EMULATOR=yes, but I do not want to rebuild for nothing, how can I find the exact settings for that firmware and just add in the FPU emulator?

Please help!
Thanks!
Patrik

Seems you have to build the image by yourself because this is a kernel feature. You can change the kernel config by the following commnad:

make kernel_menuconfig CONFIG_TARGET=subtarget

In "Kernel Type", select MIPS_FPU_EMULATOR and save the config, then rebuild the lede image for your device.

yes, it is awesome now, works!!!!
my own firmware and mips nodejs v8.
thanks so much for replying!!!
ciao!
