1.5.5.4. Add the JTAG UART

The JTAG UART provides a convenient way to communicate character data with the processor through the . To add the JTAG UART, perform the following steps:

  1. On the IP Catalog tab, expand Interface Protocols, expand Serial, and then click JTAG UART.
  2. Click Add.
    The JTAG UART parameter editor appears and do not change the default settings.
  3. Click Finish and return to the System Contents tab.
    The JTAG UART instance appears in the system contents table.
  4. In the Name column, right-click the JTAG UART and click Rename.
  5. Type jtag_uart and press Enter.
  6. Connect the clk port of the clk_0 clock source to the clk port of the JTAG UART.
  7. Connect the clk_reset port of the clk_0 clock source to the reset port of the JTAG UART.
  8. Connect the data_master port of the processor to the avalan_jtag_slave port of the JTAG UART.
    The instruction_master port of the processor does not connect to the JTAG UART because the JTAG UART is not a memory device and cannot send instructions to the processor.
