Hi,

Thanks, but I can not use the method, because the code is running before the system discovered memory, so it must be run on FLASH and no more memory used to decompress it. I think finding out why padding zeros in .reloc section is meaningful.

You can use UPX to compress your dll file, then burn the compressed version to the FLASH.

Hi,

It is problem for me. Because I very care the size of PE files which would be fired on size limitary FLASH.

Are you seeing a problem? Or are you just curious about the format?

Hi,

I don??t think the pads are filled to achieve the section alignment. Previous dump info is just with setting the file alignment and section alignment option(/ALIGN:32) of linker.

Hi,

Those zero bytes are filled to the section to guarantee the next section start at a virtual address that is a multiple of SectionAlignment value, which is part of IMAGE_OPTIONAL_HEADER structure of PE file. The default value of SectionAlignment is 0x1000, that is, even one section’s real size is only 1 bytes, 0xfff bytes of zero value will be filled to that section.

According to this, you should try to decrease this value in the compiler setting.

Search in the MSDN using “PE matt” as keywords for some useful information.

Regards,

GrepAll
