Hi all. I have some binary data that I want to program at a fixed address in flash. The data is contained in c source files that were part of my main project. I now want to move them out of the main source project and create a new project that has only these tables. I then want to program them at a fixed location in flash say 0x20000. I'm having a hard time figuring out how to create a resource-only project in lpcxpresso.

I'm mainly doing this to overcome the 128k max size limit. I've purchased the code-red nxp version with a 256K download limit but don't really want to shift from Linux to Windows at this late stage in the project, so I'm trying to find a workaround for this limitation. I have external scripts / linux utilities as build steps that I'd prefer not move to Windoze right yet.

Has anyone done anything like this or can anyone recommend a solution? I've tried using ld then objcopy but I can't seem to get ld to create a pure binary file without a bunch of symbol table stuff even with -S (and -s).

Any ideas are greatly appreciated!

-Wade

I thought Code Red had a Linux version of Red Suite 4. Maybe you should check with them.

It seems like you could just use the section attribute on the data in the new project to have the data put in the location you want.
