Can't interrupt the U-boot

[ohn0n0n0]

i'm stuck on step 7. Send any key stroke to UART to interrupt the U-boot.

it shows bootwait is on, bootdelay=2. but i can't send anything to uart. my uart usb work normal with another router.

Please make sure you connect to RX instand of VCC. Both of them are 1.8V.

Corrent for CR8806. For AX3000, I'm not sure. Because I don't have one.

somehow i still can't interrupt the U-boot. i have cr8806 too. what type of usb to ttl are you using? i'm using cp2102.

FT4232. Really expensive.

But i also try CH340. It works.

You can try to disconnect the RX. And use something to short RX and GND to interrupt

I bought a ch340g last night and it works. You just saved me a lot of time.

When I use STC microcontroller, CP2102 sometime fail to burn. CH340 always work well. Don't known why. But I never use it anymore.

Hi, may I ask how do you connect pins to the UART hole? Using soldering or articulated arm or something ... ? I hold pins swingingly and connection isn't steady.

no need to soldering or articulated.
