Re: [U-Boot] Combine zImage and rootfs in single uImage

Dear Grant Edwards,

In message jpgbbm$1hk$1@dough.gmane.org you wrote:

Currently, I build a linux kernel that contains the root fileystem in the zImage file, when then gets converted into a uImage and booted from NAND flash. This is all working fine, but having the kernel build depend on the rootfs build is a problem.

In another mailing list, somebody told me that if I was using U-Boot, I could build the zImage and rootfs separately and then combine them into a single uImage file for distribution.

The (deprecated) old style way (using legacy image format) is called "multi-file images".

The modern, recommended way to do things like this is using FIT images.

See the respective documentation.

Best regards,
