Hello Sir/Madam, I am using CCES 2.0.0 with BF548 EZ-KIT LITE. I am trying to write on the UART in blocking mode as given in the CCES example code. The code is build successfully, but at run time, an exception is thrown saying: A non-recoverable error or exception has occurred. Description: A data CPLB miss has occurred without a corresponding CPLB entry. General Type: RunTimeError Specific Type: DCPLBMissWithoutReplacement Error PC: 0xffa02bfc I tried debugging the code and found out that the error comes inside the adi_uart_open() function while registering the "UART driver status interrupt handler". I am writing on UART1 with the exact settings as given in example sketch code for BF548. The project has only the following add-ins: -> Pin multiplexing -> Startup Code/LDF -> UART Driver for Blackfin I am new to CCES so it would be a great help if you can help me out of this problem. I hope to hear very soon from you.
