Specify Memory Location for Comms Driver

jimfell — Mon, 19 Nov 2012 20:41:47 GMT

I'd like to specify a memory location for a USB driver. I've compiled the Freescale USB stack (v4.0.2) as a library, and I'd like to specify the memory location, so that the driver can be shared between main code and the boot loader. What's the best way to do this? I imagine that there would have to be a mechanism to map functions to the appropriate call address.

You need to do this with the linker file. Basically marking the functions in the source file with an attribute (segment name), and then place the functions into a memory area in the linker file.

The syntax is somewhat different from compiler to compiler (and linker to linker).

Hope this helps,
