It sounds more likely the problem is related to software build and not system/JTAG. Suggest to look in your .map file
and verify there is *no* code or data section prior to 0x60. It's possible that everything is fine, then you start to
download code and inadvertently overwrite an onchip register location, causing the process to go bad.

If you're absolutely sure that location 0x60 is the first one accessed, then suggest to manually try loading section
0x60. After loading a few words, recheck your register view and make sure nothing has changed. If you can get past
0x60, then find the next section CCS will download, and repeat. In other words, try to manually reproduce what CCS is
doing, step by step, and find the first instance that something goes wrong. Whenever that is, will be the key.

In doing this type of low level debug, it might help to write a very small program, like a main() function that
contains only a couple of lines of code -- no other .c files, no libraries, etc.
