The user encountered a 'DCPLBMissWithoutReplacement' runtime error when using CCES 2.0.0 with the BF548 EZ-KIT LITE while writing to UART1 in blocking mode. The issue was resolved through private support, and the example code (CharEcho_UART) was confirmed to work without issues. The project included Pin Multiplexing, Startup Code/LDF, and the UART Driver for Blackfin.

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.

Hi,

We understand that you have already contacted our private support. Please continue the discussion there.

We have tried to simulate your issue with the CCES 2.0.0 and example code(CharEcho_UART) which is available in the BF548 EZ-KIT LITE BSP installation path.
" <installation path>\ADSP-BF548_EZKIT-Rel1.0.0\BF548_EZ-Kit_Lite\Blackfin\Examples\CharEcho_UART "
And we don't see any issue with this example

Regards,
Kader
