IWR6843ISK: Uniflash COM port and CCS connectivity through MMWAVEICBOOST on REV D

Sumedh Vaidya

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST, , UNIFLASH

Hardware :- IWR6843ISK (Rev D) + MMWAVEICBOOST

Software :- CCS 11.1.0.00011, Uniflash 7.1.0.3796, MMWAVE SDK 3.5

 

I have configured the board using TI's training video and 6843's user guide

https://www.ti.com/lit/ug/swru546d/swru546d.pdf?ts=1648130628615&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FIWR6843AOPEVM

https://training.ti.com/hardware-setup-mmwaveicboost-and-antenna-module?context=1128486-1139154-1147568

I am trying to run TI's out of the box demo. I can run it successfully in standalone mode.

When I try to do the same in MMWAVEICBOOST mode, I run into 2 issues:-

1. Flashing device using Uniflash (shown in the training video)

Uniflash is unable to connect to the com port of the board when trying to flash the .bin file. 

2. Connecting and flashing device via CCS

If I try to flash through CCS, Cortex R4 crashes.

How do I go about fixing these issues? I would like to have CCS connectivity for debug

    Hi,

    Thanks for reaching out to us with this!

    1. Please ensure nothing else is using your com ports while trying to use uniflash (i.e. demo visualizer, teraterm or ccs). Also, make sure your SOP is set to flashing mode, in the picture attached it is in functional mode. If the problem persists trying reset the device using the NRST button the MMWAVEICBOOST board and/or manual

    2. CCS debug does not work in standalone mode, CCS debug requires the XDS110 connection on the MMWAVEICBOOST board. 

    Please let me know if these help or if the problem persists!

    Thank you,

    Angie

    Hi Angie,

    1. The result is inconsistent on my board + boost device. With the same configuration (SOP, switches and same programs running on PC), sometimes I am able to flash the device and sometimes I get the COM port open failure. I press reset multiple times. Could this be because of inconsistent reset function? Maybe sometimes it happens and sometimes not?

    The SOP was set correctly. The picture was taken later.

    2. When I checked for CCS debug, MMWAVEICBOOST was connected to the board as seen in the picture.

    Hi Sumedh,

    1. When a flashing fails I recommend closing out of uniflash and cutting off power to the MMWAVEICBOOST. Then reconnect to power and reopen uniflash. Sometimes this hard reset is needed.

    Follow up question to 1: Is this happening when you flash the out of box image, the ccsdebug image or both? 

    2. In CCS, which Out of Box demo did you build (xwr6843ISK or xwr6443?)? If it had a dss and an mss image did you build the dss image first before the mss? Did you get any build warnings or errors?

    Thank you,

    Angie

    Hi Angie,

    1. I am doing both hard and soft reset (Hard followed by soft). I am closing and opening uniflash after every hard reset

    This is happening for out of the box demo image

    2. In CCS, I am not building any demo files. I am trying to connect and flash the pre-built demo files for xwr68xx (mss and dss) in IWR6843ISK

    1. Is the flashing failing every single time, or just sometimes?

    2. Please try building the dss and the mss projects (in that order) and flashing the resulting bin to the device using uniflash. 

    Thank you,

    Angie

    Hi Angie,

    1. Uniflash fails most of the times. Rarely it works

    But from suggestion 2 I got CCS debug working which was my main issue. 

    I will mark this as resolved for now and get back to you if I need further help.

    Thank you for your support!
