> Method 2: using the switch  
> This is only valid in the new uboot (from Mar 2017).
> 
> First ssh to the router and set uboot env boot\_dev
> 
> $ fw\_printenv  
> $ fw\_setenv boot\_dev on  
> $ reboot
> 
> Then when the router boot, the router will choose which firmware to boot using the hardware switch. 1. Left side (near the reset button) → Nand flash 2. Right side → Nor flash
> 
> To disable using the switch to choose firmware function, clear boot\_dev variable.
> 
> $ fw\_printenv  
> $ fw\_setenv boot\_dev  
> $ reboot
