uImage Header Format Question

gsinde · 04-04-2011, 07:52 AM

Since I am planning on only using U-Boot for development and bypassing it in production, I need to know the structure format of the U-Boot 64 Byte file header.

I know that this contains the image file name, version, and checksum but haven't yet found the structure definition and checksum algorithm. If I locate it this week before anyone posts it, I will post the answer. Thanks, Gary

That's Great. Thanks.

I just got all my NAND and Ethernet code done and everything was booting without U-Boot. However, without the header definition, I was just skipping the 64 bytes. Now, I can make sure the checksum is correct, etc.

Dear All,

I need help in Booting custom binary file using x-loader. I need some specific calculations for the 64 bytes header used in u-boot.
How can i calculate the 64 byte header for my ..application generated binary file.

Thanks and Regard's
