TMS570 (TMS570LS20216): Linker generated ECC issue

Other Parts Discussed in Thread: TMS570LS20216, NOWECC

My linker script is based on the wiki at http://processors.wiki.ti.com/index.php/Linker_Generated_ECC but there's a note there stating that the ECC algorithm sections "...is yet not verified"  for the TMS570LS20x/10x. Also the section named example Memory Map for TMS570LS20216 is empty, so it isn't of much help.

Anyway, when I debug the Debug project I'm able to step through the code to a certain point when the stack shows that the "entry point" has been reached and I'm unable to continue stepping through the code. My guess is that the issue is related with handling interrupts and possibly something to do with the ECC algorithm section in the linker script below. 

Are there any issues with the linker script below that could be causing this? Also can somebody verify that the ECC section is correct? I have a hunch that the hamming_mask should be FMC, but I haven't been able to find this anywhere in the documentation.

Note that this is a working project using nowECC, and the issues I'm having are while trying to generate the ECC data via the linker.

My tool versions are:
Code Composer Studio Version: 6.0.0.00190
Hercules Emulation 6.0.2
