Few days ago, I have successfully applied a sample chip with TMS320C6713BZDP-300 from TI company. Firstly, i had never seen a production information with ZDP in the datasheet, that only two types with PYP and GDP are introduced. Is the chip the same with the TMS320C6713BGDP-300?
Secondly, a board with TMS320C6713BGDP-200 is working properly. And i have replaced it with the TMS320C6713BZDP-300, and the core supply voltage have increased from 1.2V for tms320c6713b-200 to 1.4V for c6713B-300. The corresponding PLL and EMIF intialization programs have changed to make sure the C6713B-300 works properly according the datasheet.
But now a very strange problem arises in my board. After running the programming for a while about a few seconds, and the DSP chip automatically disconnect with my emulator. Sometimes the disconnect error window appears but sometimes no evidences could be seen in the CCS working screen. In the later situation, the status in the bottom left corner shows that the program is "Running"(Actually the program has been terminated) but when you click the menu "Debug"->"Halt", a disconnnect error window appears. I am very confused with this. The board with c6713B-200 is working correctly and properly and never occurs this kind of phenomenon....
Any suggestion would be greatly appreciated. ..
