[Phil Q] I am not sure exactly what you are meaning by 'folder' or 'instructions that the board recognise'. When you stop the autoboot you are running the bootloader (u-boot). The only commands understood at this point are u-boot commands a list of which you can get by typing 'help' Could I make me a script to configurate the environment? [Phil Q] I am not sure why you need such a script. The idea is to allow the board to autoboot some other program (for example a Linux kernel), if you allow the autoboot to occur it will execute the contents of the 'bootcmd' variable and supplies the contents of 'bootargs' to the program it runs. The normal procedure is to stop the autoboot, change the value of either bootcmd or bootargs to suit what you need (for example changing the FLASH from yaffs2 to jffs2 or NFS. Then do a 'saveenv' and your changes will survive a reboot. So once you have the settings you want saved you no longer need to stop the auto boot - the 'script' is effectively the 'bootcmd' contents and I am not sure why you would need anything other than the default here unless you wanted the kernel via TFTP perhaps? Thanks a lot
