2k limitation code

Hi guys,

I am currently using the evaluation software C51 tool kit to compile my c code into machine code. Apparently, this version of software has a limitation of 2k of object code. At first I thought that will be a .hex file, but then after I manage to squeeze my code size to a size that the version is able to compile (before that it always comes out with a message saying I exceed the 2k limit), I realise that my .hex file is around 8kB, so it is clear that that is not the one. I would like to ask what does it mean by object code? Which will be the file that cannot exceed 2k of size? Shouldn't be the one with .obj as well I think, as those exceed 2k as well.

Thanks guys.

Regards,
Siang

  • Note that a binary file does not contain any address information. If the code has holes, then the binary file must fill these holes with 0x00 or 0xff, which means that a binary file may be bigger than what is expected from the build log output.

    Does your code contain both a boot loader and an application? It seems like the binary file has filled a gap between two code blocks to become as large as it is.
