Hi Stephen,

I finally got UART_AO_A to work with following instructions.

Instruction of how to fix 2 seconds delay at boot and not working reboot

I was looking for environment that helps me to edit/compile U-boot loader to disable 2 seconds delay at boot time…Cuz I’m completely new to some kernel editing stuff. So I create it and sharing with you guys))) + Bonus is that now $ reboot stuck bug is fixed by created boot-loader and board can reboot as expected The Official instruction doesn’t work for me (there were many errors on different stages) but you should read it to understand the process and where most files and commands were …

Thanks a lot!
