RM48L952: XDS110 debug probe emulator connection issue

Benjamin Vincent
Prodigy 10 points
Part Number: RM48L952
Other Parts Discussed in Thread: UNIFLASH,

Tool/software:

I am currently using the XDS110 debug tool through Uniflash version 8.8.0 installed, I cant seem to get the emulator to connect to the microprocessor. I have connected in the past, since then there was an auto update through the program for the XDS110 debug probe through uniflash and I have not been able to connect since, I feel like this may be a quick fix but I am not an engineer and do not know my way around Jtag or emulators in general. I was hoping to see if there is a a troubleshooting guide to the issue seen in the screenshots below as I would like to know if maybe my debug tool is no longer working properly. Attempts seen below were taken when attempting to use Uniflash v 7.1.0 and 8.8.0 afterwards.

Error -2063, Error -242, Error -1170

    Hi Benjamin,

    Which board are you using? Custom board or TI specific HDK board?

    Are you facing this issue with only uniflash or else are you facing this issue with CCS as well?

    Technically custom for TI standards but it is manufactured, I've only ever used Uniflash and never CCS, currently just using a pre-loaded program given to me to program the RM48L952 cpu. It seems like I can't establish proper communication between the two devices(XDS110 and RM48L952) and this happened after the auto update for the debugger tool, but there is still no issue communicating with the XDS110 to the Uniflash program. 

    I attempted to downgrade both the uniflash software to match the old XDS110 software, but I could not find the software install program for the XDS110 itself, now its all comming down to JTag settings that I am not quite sure how to manipulate. I thought maybe there would be a quick setting I could access, hoping it would be as easy as running a quick troubleshoot and re downloading the emulator. 

    I will look into CCS to see if it will help as well

    Hi ,

    If you are sure, it is due to firmware upgrade then do the following steps to find out the firmware version in the xds110:

    1. First install latest CCS in your system (for example in my PC i installed 12.7.1).

    2. Now connect the board to the PC and open the cmd window in PC.

    3. Now execute the below command based on the CCS installed path:

    cd C:\ti\ccs1271\ccs\ccs_base\common\uscif\xds110

    4. Now execute below command to find out the xds110 firmware version

    xdsdfu -e

    As you can see my board's xds110 consists of firmware versions 3.0.0.29, and i don't see any issues with this firmware version and i was able to program the board from both uniflash and CCS.

    Let's check what is the firmware version present on your board with above procedure. Based on that we will take action.
