Re: [U-Boot-Users] Replacing AT91 u-boot
AFAIK loader.bin is used to download boot.bin to RAM location.
Correct
boot.bin itself is an u-boot binary image. It is straight executed after downloading. Now it's possible to install a new u-boot version.
Definitely not. BTW binary sizes are too different to say that boot.bin is 10KB loader.bin is 7KB u-boot is 92KB
Referring to Atmel manuals boot.bin is a pre-loader ususlly stored at the beginning of flash (0x10000000) which calls u-boot (usually stored at 0x10010000). You can found sources for loader.bin and boot.bin on Atmel CDROM and until last saturday on this website. http://www.at91.com/Pages/products/EvaluationBoard/AT91RM3400DK/at91rm3400dk... Today these sources have been removed (I don't know why ?)

Yes, you're right. But why do you want to install the boot.bin binary. You should create a normal u-boot binary file (not a compressed image) and store it in flash at 0x10000000 instead of storing boot.bin and a compressed u-boot image.

This a the point, it normally doesn't make any sense to use boot.bin, use u-boot directly.
