CCS/TMS320F28335: The board is not connected to PC via RS232

Part Number: TMS320F28335


Tool/software: Code Composer Studio

Hi everybody,

i have a board which is produced by Technosoft. The boad has a f28335, RS232, and JTAG pin. The board is connected to pc via RS232. Normally the card has a special program and the card is connected to this program via RS232. I got the XDS100V2 to program the card from the Matlab Embedded coder and CCS. I didn't anymore connect to the card again via RS232 after I programmed the card via jtag. Why can't I connect to the card anymore.

  • You likely erased the "monitor" program in flash that enables communication via the SCI. Unless you restore the monitor program, you will not be able to communicate to the board via RS232.

    The basic communication programs between the MSK28335 DSC board and the PC are MON28335 (on the MSK28335 DSC board) and MONPC28x Monitor (on the PC). Figure 1.4 shows the basic structure of these programs.

    MON28335 - the monitor program of MSK28335 DSC board - uses the SCI interface of ‘F28335 for serial communication with the PC.
  • Thank you very much.
