To access any external memory space (CE0, CE1, etc) using CCS + JTAG, you need .gel
file.  As before, my suggestion is to take DSK C6211 .gel file and edit, first remove
any reference to things you don't have (LEDs, user switches, etc) and keep CEn
initialization only for CE2 space, which should be asynchronous.

It's possible that your peer group before you 3 years ago didn't try to access
external memory with CCS, they just ran DSP code to perform CEn initialization.
That's one way, but the correct and more flexible way is to allow both CCS and DSP
code to initialize and access CEn space.

If you have crucial deadlines, then I suggest to answer the questions posed to you
without delay, and be very careful and meticulous in reading the replies to you.
Starting with:  what JTAG emulator do you have?  What version of CCS?  I think you've
been asked those questions a few times now.
