CCS/IWR6843ISK: UNIFLASH gets stuck trying to flash IWR6843ISK

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

Tool/software: Code Composer Studio

When I use uniflash to program my IWR6843ISK, it gets stuck on the Load Program phase, Loading Images, Opening COM port COM9. I've been debugging this for some time and have tried everything. Tried removing and reinstalling the TI cloud agent multiple times. Tried Firefox and Chrome browsers. Tried cloud and offline versions of uniflash. Every one has the same results. I checked and double checked the COM port in device manager. I have the proper SOP jumpers on the board for flashing. I even tried to use my MAC book but there's no installer for the MAC for the mmWave SDK which I require for the flash image.

I'm completely stuck. Any experts that can help me? Maybe there's some back door logging I can look at?

Below is the dialog box it's stuck at (let it sit for at least a half hour). It gets through all the other stages up to that point. It even auto-detects my board.

BTW, I'm running Windows 10.

  • If it helps, here's a screen shot of the uniflash console

  • Hi Brad,

    Can you send me the program you are trying to flash?

    Thanks

    Can you also provide a ds log?

  • I'll send you the bin file separately, it's a prebuilt binary from the mmWave SDK located at C:\ti\mmwave_sdk_03_03_00_03\packages\ti\demo\xwr68xx\mmw

    I enable the logging as per your instructions. I pasted it in below but I don't think it tells us much. Maybe theres an issue with the log because once I enabled the logging then started to program the flash, it gets stuck and I have to kill the browser then start again.

  • Thanks Brad. I got your e-mail and and was able to successfully flash the file to my IWR6843ISK using UniFlash 5.3.1 (desktop version). The UniFlash expert suggested forwarding this thread to the mmwave experts since they have implemented the COM port communication for this. I will move the thread to the device forum to bring it to their attention.

    Thanks

  • Hi Brad,

    Can you please confirm the rev of IWR6843ISK and MMWAVEICBOOST that you are using?

    Can you also share a picture of your setup?

    BR,

    Charles O

  • Sure, see pics below. FYI, these are new boards I just received, fresh out of the box. Based on the pics, I'd say rev 1 of the carrier board and ES2.0 silicon for the sensor

  • Charles,

    Thanks for the assistance. Based on the comparison to your board that works, my board had a jumper on J13 between pins 1 and 2. Based on the user guide, that jumper by default should be open. Removing that jumper resolved the issue. I can now flash my board.

    THANKS!
