AWR2944EVM: CCS and Uniflash connection issue to the EVM

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944, UNIFLASH

I recently bought a ES2.0 AWR2944EVM (RevD) and downloaded the mmwave_mcuplus_sdk_04_04_00_01 from https://www.ti.com/tool/MMWAVE-MCUPLUS-SDK.

Next, I tried connecting to the board and flashing a precompiled version of the SBL (C:\ti\mmwave_mcuplus_sdk_04_04_00_01\mmwave_mcuplus_sdk_04_04_00_01\tools\awr294x\sbl_qspi.release.tiimage) and CCSdebug image (C:\ti\mmwave_mcuplus_sdk_04_04_00_01\mmwave_mcuplus_sdk_04_04_00_01\ti\utils\ccsdebug\awr2944_ccsdebug.appimage) using uniflash.(Version: 8.1.0.4135). However, I got the following error:

I have verified the SOP0 and SOP2 jumper connection, USB cable connection and the COM port.

I also tried to connect to CCS using configuration I have successfully used for another 2944 board. I see 2 different behaviors on 2 different boards here. In the first case, the cores connect for a few seconds and then disconnect with the following error:

In the second case, the cores don't connect at all:

Please help me solve this issue.

    Hi,

    For the flashing issue with the Uniflash software please ensure the below points.

    • Please make sure that you have set the right SOP jumper (SOP0 and SOP2) on EVM in order to put device in flashing mode. Do the power cycle after putting the jumpers then start using Uniflash.
    • Make sure the COM port number is correct in the Uniflash ‘Settings & utilities’ TAB. This COM port should be the number which is populated as a “XDS110 Class Application/User UART”.
    • Disconnect and connect the USB cable if Uniflash is not able to access the COM port.
    • Check the power supply if it is according to the spec. (5V ~3A)
    • If Uniflash was crashed or closed forcefully in last session then try to kill these processes from TaskManager – “DSLite.exe” and “Python**” and restart the Uniflash GUI. [TODO] find the 2nd process name.
    • Try different PC to use the Uniflash. (if above doesn’t resolve the issue)
    • Update to latest Uniflash version if using old version of it.

    Let us know if you observe the same issue after following all the above steps.

    Thanks,

    Pradipta.

    Hi Pradipta,

    Thank you for suggesting these steps. I have tried all of these, short of trying on a different PC (I don't have one on me right now, can do Monday) but none of them seems to work. It does however, work on a different EVM/

    Hi,

    If these steps are not working, then you need to check if the EVM has been damaged permanently. Did you apply more than 3A to the EVM? 

    There are no other checks or steps we have for this. 

    Thanks,

    Pradipta.

    Hi Pradipta,

    The power supply I used is rated 12V 3A and is pretty stable (been using it for other EVMs no problem).
