Question about boot from UART for C5535

Other Parts Discussed in Thread: TMS320C5535

Hi community member:

      According to the following application note, C5535 support the boot via UART.  www.tij.co.jp/.../sprabl7b.pdf


      There is a  connection via  UART2 for communication between TMS320C5535 and  ARM.

      1)Rx and Tx are connected.


      2)RTS and CTS are not connected.( Support of Ti tell me that is  not necessary)


      3) The following UART parameters is configed : 8-bit data, odd-parity, 2stop-bit, and 57 600 baud rate, flowcontrol is none.


      When Arm run ,It will delay for 3 senconds for be ensure the  bootloader of Dsp is listening. Then the DSP bin file is sent to  C5535 via UART2 ,  60B per packet . There is no error occur in the process in logs of Arm. But the DSP bin DSP be runin the RAM of DSP.


       Is here any error for I do ?


      How I can knows what happen about bootloader of DSP.


Best regards.

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com).

    I have notified our experts they will get back to you as soon as possible.

    Note: We strongly recommend you to create new e2e thread for your queries instead of following up on an old/closed e2e thread, new threads gets more attention than old threads and can provide link of old threads or information on the new post for clarity and faster response.

    IF RTS & CTS is not be supported , can C5535also perform UART boot from other external UART transmitter ?
