    UDB UART Rx does not work with DMA in PSoC4

    user_473032933

      Hi,

         

      I need a little help here.
      I use a UART component in a PSoC4 project and I would like to save incoming bytes to RAM without CPU intervention.

         

      I do not know what I am missing but it does not work to me.
      I attach a simple example of using DMA and UART RX facing my issue. It can run directly in the Pioneer kit.

         

      The examples for DMA and UART RX use the SCB blocks, which is not an option for my application since the SCBs are reserved for other serial communication blocks. My only option is the UDB UART mode but IU cannot make it work.

         

      Any ideas?

         

      Thank you very much in advance.
      Best Regards,
      Yiannis
