Does setting bootdelay to zero meet your requirements?
This does not diable the serial console. You still get all the output, and if any of the commands in your "bootcmd" definitionis interactive, it will accept input, too.
Thanks for your concern on this point. Actually speaking, I am a little puzzled toward the fact whether to disable serial console or not. Anyway, debugging on spot is a necessary sometimes. I don't want to solve a simple problem with BDI2000 every time.
One good thing is that I can implement above idea on RPXlite DW board in a standalone way. But the bad one is that my custom board must connect a serial line to HOST PC in standalone way or LCD console will directly stop at u-boot command status without any downcounter as if the serial console accepts input. Hardware difference is there is no CPLD on my custom board. Does this make the difference? My hack method is to fix common/main.c to disable any serial input for my board. It worked but I couldn't switch to serial console anymore. So sadly...
Maybe this is also one reason why I'd like to disable serial console completely on my custom board so that I could avoid breaking main.c.
