LAUNCHXL2-RM46: LAUNCHXL2-RM46

Part Number: LAUNCHXL2-RM46
Other Parts Discussed in Thread: RM46L852

Tool/software:

I am using CCS Version: 12.1.0.00007 .

I just received the LAUNCHXL2-RM4

I connected it to my PC and I see the below in Device manager

XDS110 Class Application/User UART (COM35)
XDS110 Class Auxiliary Data Port (COM34)

CCS does not detect the board. It also does not list it as one of the options.

I also tried updating the XDS110 firmware in the below directory

C:\ti\ccs1210\ccs\ccs_base\common\uscif\xds110

The firmware updated successfully to below

VID: 0x0451 PID: 0xbef3
Device Name: XDS110 Embed with CMSIS-DAP
Version: 3.0.0.22
Manufacturer: Texas Instruments
Serial Num: HLRM46xx
Mode: Runtime
Configuration: Standard

I still cannot get CCS to see the board. When I click on the detect board I sometimes get the below message

"Unable to open USB device-ensure drivers are installed (LIBUSB_ERROR_ACCESS)

I also tried running CCS in administrator mode and still it does not detect the board. 

Any suggestions on what to try? I looked for USB drivers but did not see anything. Since device manager sees the XDS110 I assume the drivers are working.

    Hi Gary,

    Is it possible to setup one live debugging session so that i can see and guide you?

    Let me know what to do and at what time. I am available anytime day or night. My time is eastern time USA. 

    It could be an issue with my board. I have a sperate PC that is new. Its running windows 11. I downloaded and installed the latest CCS. It gives the same problem and does not see the board.  Or maybe I am using CCS wrong. I basically clicked on the "Browse and Import Examples" from the getting started screen.

    I just realized my version 12 is not the latest version 12 even though the check for updates said there are no updates. So, I downloaded version 12.8 and selected the Hercules support along with many other processors. It still does not list the LaunchXL board as an option and does not see it when I check for board. I was able to create a project and select the RM46L852 chip on the board and setup a target config. I was able to compile some simple code and connect to the board. 
    However, I have not found any Hercules example code anywhere. 
    I was assuming I would be able to just plug my board in and get access to some simple sample projects.

    Hi Gary,

    I am attaching one simple LED blinky project for RM46 Luanchpad:

    LED_Blinky_TEST_RM46_Launchpad.zip

    In this project i am blinky two user LED's for every 1Sec.

    After downloading and extracting this project.

    Import the project into CCS and after importing it make sure your project settings are as below:

    Once you did this you can directly debug the project and can see the LED blinky.

    It is working without any issues on my end.

    If you still have issues then we can connect over a webex call there you can share your screen and explain the problem and i will give my suggestions.

    Thanks Jagadish. This will be helpful. Sorry for the slow response. It was a Holiday last week in the US.
