    Thread Summary
    
                The user encountered a linking error and issues with UART DMA transfer on the ADSP-21489 EZ-KIT. The problem was resolved by ensuring the baud rate was correctly set to 19200 on both the DSP and PC. For continuous data transfer, the user was advised to use UART DMA chaining mode and verify the UART settings and signal integrity with an oscilloscope.

    Dear Sir,
    
 
    Please provide me an example code in C for the above requirement. When I'm modifying the UART echo example for core interrupt to DMA interrupt during linking it shows error in IDDE as fatal error : Link failed and The following symbols referenced in processor "P0" could not be resolved: 'length[_length]' referenced from '.\Debug\UARTDMA transfer.doj'
    
 
    please help in this regard as soon as possible.
    
 
    regards
