Every time I boot Armbian on my tv box, there is always a 5 second prompt on startup similar to entering startup options on Windows. I'm not entirely sure what it's for, but i'm assuming it's a barebones u-boot command line. The problem is, I don't need it, and it adds a significant amount of time when booting. Does anyone know how to remove it entirely and to boot directly into the kernel? 

 

I'm using a Tanix 3 mini with Armbian 5.9.0

@Jeebus - it comes from CONFIG_BOOTDELAY=5 in the config used when building u-boot - in case your u-boot is saying something about hexdump in its output then here are some notes on how it was built: https://github.com/hexdump0815/u-boot-misc/blob/master/readme.gxl - in the end you'll have to build your own u-boot in case you want to get rid of it ... the idea behind it is to have a chance to press a key at this point to enter raw u-boot cmdline to fix things by hand in case your setup got broken ...

Big thanks for the support. I'm familiar with linux mainly from raspberry pi and never had to do something like compiling a kernel or building my own u-boot. Can you point me in the right direction of how to go about this?

 

Much appreciated. 

setenv bootdelay 0
saveenv

This is in the u-boot command line im assuming?

I noticed I don't have a saveenv command- if i'm not mistaken it seems that some boards don't allow editing u-boot. Correct me if i'm wrong

the u-boot setup on amlogic tv boxes is very special - a legacy u-boot is chainloading a mainline u-boot and it is very likely that saveenv in this setup simply does not work ... the readme linked by me above at least gives a rough idea about the steps to build it, but maybe its not really easy for someone not used to build u-boot all the time ... i'm not having the time right now to take care of it myself
