Hi
Could anyone tell me the differences between TMS320C6678 Silicon Revision 1.0 and Silicon Revision 2.0?
I have found some information in SPRZ334E that the revision of C66x CorePacis is 1.0 in Silicon Rev. 1.0 and
the revision of C66x CorePacis is 2.0 in Silicon Rev. 2.0. What's the difference between two revision C66x CorePacis ?
Are there any other extra differences between TMS320C6678 Silicon Revision 1.0 and Silicon Revision 2.0 ? Do these
differences have impact on my own software design or hardware design? By now i have encounter some questions :
I have two TMS320C6678 boards, one is TMDXEVM6678LE Rev. 1.0 with IBL version 1.0.0.4 and the other one is TMDSEVM6678LE Rev.3B with IBL version
1.0.0.16 . When i write IBL 1.0.0.4 to the E2PROM of TMDXEVM6678LE Rev 1.0, the device can boot successfully, but when i write the same IBL to TMDSEVM6678LE Rev.3B,
the DSP can't boot. Then i print some information through the uart . Find that the 1st stage of IBL operates failured. I change the IBL source code and rewrite it to
E2PROM after rebuild it. The result is that the 1st stage of IBL runs successfully, but my application program still boots failure. I guess the problem occurs in the second
stage of IBL. By comparing the two version IBL, I find too many differences. Does the IBL 1.0.0.16 backward compatible to old release ? Does other software have the
same problem ?
Thanks
