I have been using several different embedded boards that store kernel, init files, filesystem, etc. on partitions of a (micro)SD card. I notice in the example usage or instructions that compressed image (
zImage) is loaded to the corresponding partition of the SD card (let's say sda2).
I wonder if it would be fine to load uncompressed image file (Image) to the
If it is a fine case, would the board boot some seconds faster than the one that has zImage or the difference would be insignificant?
And, is there any specific reason to use zImage apart from saving storage space?
