CC2652P: unsupported library

Part Number: CC2652P

just out of reset, the Launchpad hangs while checking a library consistency.
I' m using simplelink_cc2640r2_sdk_5_30_01_11 dev support and cc2652 chip on a LP board. What have I to do to solve it?

    Hi !

    I'm not sure that I understand what your issue is. What do you mean by "checking a library consistency" ? Is this something that you have added yourself in the code of the application ? Do you have an error code ?

    Kind regards,
    Lea

    Hi Lea,

    after reset, a library check is performed and the code stalls as in the attached pic (see red arrows). Note the LaunchPad was recently purchased from a distributor of yours, it is populated with a CC2652R1F C . No way to proceed

    Can you tell me how can I solve this?

    Thanks, Luigi

    Hi !

    The CC2652P chip that you are using is in revision C, which is quite old, more than 5 years old. The driverlib library version that is shipped in the latest SDK is incompatible with CC2652P chips that are below revision E.

    You can see in this post :  [FAQ] CC13x2, CC26x2 Revision E and SDK version compatibility 

    • All silicon released before the device production will be “x” marked and can either be Revision C or Revision E

    In order to prevent incompatibilities with the library versions, TI has introduced a check to make sure that the chip running the firmware is at least on revision E. This is why you are entering a while loop forever.

    This means your only 2 options are to either use an SDK which is outdated by 5 years and not maintained, or to upgrade to a Revision E silicon. Can you give more details as to how you obtained this chip/which revendor did you use ?

    Kind regards,
    Lea

    Hi Lea,

    I supposed there was a similar issue. Unfortunately the Launchpad was purchased on Oct 2025 from Mouser but now it seems to me that LP is further no longer available since the appearance of the new LP is different from that I' m dealing with. So, some other questions:
    1) if I replace the chip on the LP with a latter one, can I maintain the same features?
    2) I need also energy trace functionality: is this available simply by replacing the chip on my LP?
    3) is it better to purchase a new LP, but can I be sure there will be no longer this issue? Taht is, can I be sure the selled units are up to date?

    Thanks

    Luigi

    Hi !

    For the energy trace functionality, this is handled by the debugger. If you own a XDS110-ET, you will be able to run energy trace on your device.

    As for the LaunchPad purchase/replacement, I think you should send an email with Mouser to shed light on the situation. I can't guarantee that buying a new LaunchPad from them will result in them sending an up-to-date chip revision, so my advise would be to get in touch with them to make sure of that. They should be responsible for not selling customers like you outdated hardware by 5 years.

    Kind regards,
    Lea

    Hi Lea,

    you were very clear. FYI, I replaced the original CC2652 on the LP with a CC2642 (which is really the base of my application) recently purchased from Mouser itself and marked TI 368 F AQTK G4 and all is going fine. It seems to me this is the easiest and fastest way to solve this issue, instead of complaining with Mouser for their selling and wasting more time. Anyway I will inform Mouser to pay attention and not sell an outdated product, probably remained in their warehouses without them noticing. Many thanks, have a nice day. To me, this issue is resolved
