Petalinux 2016.2 Use a pre-exisitng rootfs

Jump to solution

 

I want use a pre-exisiting rootfs for zynq board for simplicity. (contain most desired packages)

How i can use a exisiting rootfs such an ubuntu rootfs (that is default rootfs on many boards)

with petalinux.

For clarify:

Suppose i generate image.ub and BOOT.BIN with petalinux-package command (copy them to FAT32 partition) and also didn't use

petalinux-config -c rootfs

Because i want use a pre-exisiting rootfs.

Therefore can i copy-paste default ubuntu rootfs (or any other rootfs) to ext4 partition?

Is there any special thing about rootfs that i copy to ext4 partition?

You can simply copy-paste any rootfs to the ext4 partition and use it. Do not forget to select SD card as the rootfs type.

Rootfs libraries that we used, should be compiled for ARM architecture. So they can be used. Isn't it?

Of course. You can find pre-installed root file systems for arm architectures by following these links
