Hi,
I am working on developing a radar solution using AWR1843. For that I am referring to the reference design of the EVK (AWR1843BOOST).
As per my understanding of AWR1843BOOST, XDS110 (TM4C1294NCPDTT3) is used for JTAG and UART connections. I don't intend to use these connections & I want to safely remove the XDS from the circuit.
Kindly let me know the following:
a. Without XDS how would the firmware be flashed to AWR1843? Do I need an external debugger or can I send the firmware directly over UART? If external debugger is required which external debugger/flasher I need to buy?
b. Which pins from the AWR1843 are used for flashing the firmware (That I need to leave out open in my design). According to my understanding it should be TCK, TDI, TDO, TMS. Please confirm?
Hi,
I recommend searching the forum for similar threads using google site search
For example

Here are some threads
Thank you

Hello,
The RS232 pins are used for flashing the application to the device (N4 and N5 on AWR1843).
You do not need an external debugger, you can use an RS232 to USB cable like mentioned in the thread Cesar has linked and connect directly to the RS232 pins.
The JTAG pins (TCK, TDI, TDO, and TMS) would require an external debugger like the TMDSEMU110-U to connect to a PC for debugging. It is recommended to provide access to these pins for debug purposes and for developing your custom application. However, once you have developed your own custom application you can flash the device using RS232 and JTAG would not be needed.
REgards,
