[U-Boot] rk3288 (Tinkerboard) not booting【请注意，邮件由u-boot-bounces at lists.denx.de代发】

[Alexander von Gluck IV]

ACK! I'm on UART1. Mix that with video potentially not working
in u-boot and I think I have my answer.

I'll test this afternoon.

(PS, since the Tinker is supposed to be "Raspberry Pi like", why would
u-boot present on UART2 on it while the Raspberry Pi u-boot uses UART1?)


Thanks for the help!
