Part Number: IWR1443
I have a IWR1443 based custom PCB which I am trying to program using TMDSEMU110-U. I have connected UART port RX and TX to corresponding Auxillary port TX and RX and have connected a common GND. I have ensured SOP setting to the flasing setting. I am unable to program using UNIFLASH. It says it is unable "Not able to connect to serial port". Are these connections and my procedure correct to load the program?
I'll need to discuss this with our hardware team. We should have an answer for you sometime next week.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

sounds like you are following the right steps.
In reply to Charles Oladimeji:
I can confirm all the steps you have mentioned. Today I tested on my IWR1443BOOST by populating R166 and R169 and connecting AR_RS232TX and AR_RS232RX from J5 to my debugger. I have additionally connected GND and also powered my device. I am still unable to succeed.
In reply to Prudhvi Sagar:
When you connected the RX pins to your debugger, did you removed the resistors routing the UART to the onboard XDS110?
No I haven't removed them. I can try with them removed tomorrow.
I have tried after depopulating the UART resistors aswell. Still I am unable to succeed. Same behavior is being repeated. I am confused as in what the issue is. Do you think the connecting cables are causing the issue? I am in a process of making a custom PCB and am confused to how would I program it.
The issue shouldn't be caused by the cable.
Can you try programming the board using the onboard XDS110 and then sending the config and data using the emulation board to confirm if its an issue of compatibility with Uniflash?
You can also just use a USB to FTDI cable instead of the XDS110 debug probe.
We have tested this solution and had no issues.

I assume you were able to resolve this and will be closing the thread. Please reply if you still need assistance or make a new post referencing this one.
I am still trying and unable to succeed. I am unsure how to program the board and confused how to give pins tp flash for a custom PCB.
