The firmware image.elf-0x00000.bin is different when build on PC and laptop #61

Hi,

I found this problem. Seems the content of the two firmwares on PC(thinkstaion) and laptop(thinkpad&macbook air) are the same, but the order of them are different. It's wired and I want to ensure they are the same.

Is it associated with gcc command or CPU architecture? I am not familiar with these. Could anyone give me some suggestion to ensure they are the same?

Thanks.

It is entirely possible for there to be minor differences between output binaries. It is a nondeterministic process. But the output code should work across platforms.
