U-Boot Config Parameter not used

Question

Blockquote

I am using u-boot as an bootloader for an embedded device. Since i want it to boot very fast i wanted to do some modifications on the configuration (defconfig) and rebuild it. I set the CONFIG_BOOTDELAY paramter to zero and it also appeared in the .config configuration file =0.

The problem is that when i try to boot the device that the bootdelay is always set to 1. I don't know where the bootloader is getting this paramter.

I am using a BeagleBoneBlack Rev. C with a Debian Distribution. C

Does anyone know where the value is coming from? I also checked all the uEnv.txt...
