NETGEAR R8000 Nighthawk

• Second data partition (79 MiB) not available in OpenWrt
• For a proper performance use:
  • radio0 for the higher 5 GHz band (channel 149 or something else, depending on country)
  • radio2 for the lower 5 GHz band (channel 48, or something like that and lower)

• soc.broadcom.bcm53xx

As of OpenWrt 19.07, the R8000 can be flashed to OpenWrt through the stock web UI.

1. From the 'Firmware Downloads' tab above, download the most recent 'install' build of OpenWrt (as of this writing, openwrt-19.07.1-bcm53xx-netgear-r8000-squashfs.chk)
2. Connect your computer to the router via wired ethernet.
3. Go to the stock web UI; navigate to the firmware upgrade page.
4. Upload the .chk file from above, click 'upgrade', wait a couple of minutes.
5. Navigate to the OpenWrt web UI at http://192.168.1.1 in your browser and set up the router as desired.

The CPU of this device does not provide VFP support:

# grep "\(model\|Feature\)" /proc/cpuinfo
model name      : ARMv7 Processor rev 0 (v7l)
Features        : half thumb fastmult edsp tls 
model name      : ARMv7 Processor rev 0 (v7l)
Features        : half thumb fastmult edsp tls 

Runnning ARMv6 or ARMv7 targeted Go executables on that platform will result in Illegal instruction errors.

The work-around is to target ARMv5 during compilation:

# export GOOS=linux
# export GOARCH=arm
# export GOARM=5
