NiosII about uclinux

> Can you tell me how to compress the image?

You can use gzip. For example,

$ gzip --best linux.bin

This will replace linux.bin with linux.bin.gz. To recover

the original:

$ gzip -d linux.bin.gz

This of course will require a bootloader that can decompress.

The u-boot boot loader supports gzip decompression. However,

the current u-boot port for Nios-II requires an update to fully

support the linux boot command (bootm). A update should

be available within the next few weeks.
