My ADSP-21489 EZ-Board works well since 2011.6. However, something is wrong today. Running the example project "21489 AD1939 C Block-Based Talkthru 48 or 96 kHz " of ADSP-21489 EZ-Board , I got the information as followed:
*** Port doesn't exist or isn't opened *** with PC at: 0x8c6ab.
That is say the program is stopped in the line " while ((*pSPISTAT & TXS)) " of Configure1939Register function.
Would you please help me how to solve the problem?
