Part Number: CC2340R5
Other Parts Discussed in Thread: UNIFLASH

Hi,

I am using dslite to program cc2340R5 but meet this issue.

I though it should just update ccfg, but not sure which part is incrrect.

Could you please help on this? 

Thanks.

    Hello Aichi Chen,

    I hope you are doing well. I wanted to ask if you already tried to chip-erase, and then re-flash the board; or any other iteration of this process you tried with UniFlash. What SDK version are you using, CCS version,  and What SDK example project is this based off of?

    Did you first connect the XDS110, then the CC2340 launchpad?

    Thanks,

    Sorry for my question is unclear, I mean if I got the IC in factory, nothing flash into cc2340, how do I do flash by dslite?

    We are using UniFlash Version: 8.4.0.4458 and SDK version 7_20_01_10   

    Following  steps are our procedure for operation :

     

    1. Erase flash of cc2340r5 using UniFlash (Setting & Utilities -> Manual Erase -> Chip Erase) to revert the chip to its original state.
    2. Use UniFlash's Standalone Command Line -> Generate Package
    3. Run the generated dslite-Cortex_M0P.bat script.
    4. The displayed error is as shown in the image

    If there is already firmware in the chip, it won't fail, and it can be programmed normally through dslite,

    But chips intended for production should ideally have no firmware in their initial state,

    Do you have any ideas? Or could you teach us alternative methods to enable programming on the production line?

    Aichi Chen,

    New launchpads come programed with an BLE example on them already, but devices out of the factory do not have a firmware image. In order to flash devices that do not have any firmware image on them (no ccfg) there is a special setting that needs to be enabled (so dslite can first load through the debugger into the device), the setting is " --mode noConnectFlash". 

    > c:\ti\uniflash_8.2.0\dslite.bat --mode noConnectFlash --config C:\Users\...
Executing the following command:
> "c:\ti\uniflash_8.2.0\deskdb\content\TICloudAgent\win\ccs_base\DebugServer\bin\DSLite" noConnectFlash --config C:\Users\...

For more details and examples, please refer to the UniFlash Quick Start guide.

    Thanks,
