Hello,I’m Jeff from Korea.

I wanna use the UART of RK3288 Dev. Board.

I exactly followed everything of the guide in the homepage at “Using UART”

But it didn’t work at all.

I don’t think , I missed something of the guide.

Please help me

Thank you for your support

Do you resolved your problem？Can you list your steps of yours？ You want to use UART in linux or Android？ If linux，I suggest that after you altered the dts file，follow the guide in the homepage at “Build_kernel” to build boot.img and resource.img，then burn them into RK3288.

It will be better If you show pictures about what’s wrong with your RK3288
