I am building a compressed uImage using kernel 3.6.30 for my board package which uses an Atmel arm9m10 SOC. Board package was derived from an AT91SAM9M10-G45-EK evaluation board. I am trying to check my build against a previous build using the size of the compressed image for verification. The size is not consistent between builds using the same root directory for the kernel tree. Between the first and second build may see variations of 4 bytes. Based on the root directory this may vary as much as 32 bytes in my testing to date. The vmLinux image appears to always be the same size. I am wondering if the variation is normal and if so, how does one verify between builds of a compressed (uImage) kernel. Thanks…
