CCS/TMDSEMU110-U: C28xx_CPU1: Warning: Failed unlocking device (zone 1) after reset. C28xx_CPU1: Flash Programmer: Error erasing Sector A. FMSTAT value = 0. Operation Cancelled (0).

Part Number: TMDSEMU110-U
Other Parts Discussed in Thread: TMS320F28075,

Tool/software: Code Composer Studio

As you can see,when I debugged my project,the errors were present like above.

My IDE is CCSv8.2,and I picked TMDSEMU110-U as the debugging tool for TMS320F28075.

I could build the project,but when I debug the project,I got the errors shown above.

Before all of these,my IDE is CCSv6.2,debugging tool is TMDSEMU100-U,and the chip is still F28075.

So,what should I do?
