RT-N12E b1 and RT-N12+ are clones of RT-N11P

you can take n14 dts as a base, but some button and led gpios have to be changed

Hi,

I'm trying to get OpenWRT running on a RT-N12E B1. Would you care to provide some more detailed steps of how you got it to work? Is it necessary to access (i.e. solder) the UART?

Unfortunately, I'm not even really sure I'm getting the device to enter rescue mode. When switching on the device while holding the WPS/reset button, the wifi, WAN and ethernet leds start to blink slowly, while the power led is continuously on. I'd assume that means it is in rescue mode, but the ASUS manual states that the power led should blink slowly. Which it doesn't. Might be that ASUS guys don't themselves remember how their devices work...

Anyhow, when the device is in the assumed rescue mode, I'm able to tftp the RTN-14U package to the router, and after the package has been transmitted, the router reboots. However, it just boots its own original firmware, no sign of OpenWRT.

I've also tried to use that ASUS rescue tool on Windows, but that just keeps telling me, that the router is not in rescue mode (though the tool is apparently able to detect the router, since it does not give me that message when the router is not connected at all).

Thanks for any pointers.

Re: Support x Asus RT-N12E B1

could you please assist me with this config...

just a general guideline would help. Thanks

Re: Support x Asus RT-N12E B1

I'm just about to submit a patch for LEDE trunk for RT-N12Eb1 / RT-N11P / RT-N12+. Based on wikidevi and other sources they all share the same board (FCC ID MSQ-RT1901).
