CC1352R: Silicon revision and SDK SW compatibility?

AnBer

Part Number: CC1352R


Team,

Customer is using the CC1352 Launchpad. The device marking is:
XCC1352
R1F3
TI 74J
PF3L G4

The silicon errata (at http://www.ti.com/product/CC1352R/technicaldocumentsgives a marking that matches this for experimental devices.
Can you confirm that experimental devices are PG1.1?

Have we released launchpads with PG other than 1.1?

Can there be incompatibility with the latest SDK SW?

It seems that Cortex M CPU is generating some exception when running code from the  the newest SDK 2.10.00.48 .

Thanks in advance,

A,

    As far as I know only PG1.1 is used for the LPs. The 2.10 SDK is tested with this version.

    Please give more details about the issue you are seeing.

    Hello,

    I am the said customer that AnBer talked about and the Launchpad we use are pretty old, I believe we received them before the CC1352R was released.

    The issue I see is I get locked in an infinite loop here :

    /* CC26X2 PG1.0 trap. If we are running on PG1.0, spin forever.
* This hardware revision is no longer supported. This trap is
* provided to aid in automatically identifying PG1.0 devices
* in circulation and will be removed later in the year.
*/
if (!((HWREG(FCFG1_BASE + FCFG1_O_TFW_FT) % 10000) >= 683)) {
    while (1);
}

    in the Power_CC26xx.c so my guess is we have Launchpads with a PG 1.0. We ordered new Launchpads from TI store and it seems to be working fine with those.
