Other Parts Discussed in Thread: CC3200MOD, CC3200

Hi TI team,

during our development with the CC3200MOD we faced following issue:

we reboot our device issuing:

PRCMSOCReset();

after reboot be read back the reset cause.

uint32_t hal_reset = MAP_PRCMSysResetCauseGet();

hal_reset contains the value 0x00000000

while it should contain the value for SOC reset.

Is that a known issue of the CC3200 or the driverlib?

Best Regards,

Matthias

What version of the driverlib are you using?

I have contacted the person with knowledge of this question. Hopefully he will respond to this post.

Matthias,

I've pinged the experts on driverlib about this. Hopefully they will respond directly in this post.

Hi Matthias,

Due to known issues using PRCMSOCReset, It is advised not to use the API. To Reset the SOC you can use the utility routine Utils_TriggerHibCycle. Wake up after this reset would return PRCM_HIB_EXIT if you call MAP_PRCMSysResetCauseGet.
Please find additional info in the threads below.

e2e.ti.com/.../351308
e2e.ti.com/.../1253913

Btw even though there are problems with PRCMSOCReset in effectively resetting the SOC the API MAP_PRCMSysResetCauseGet should have returned the correct reset source.

Thanks and Regards,
Siddaram

Hi Siddaram,

thank you for the quick reply, unfortunately i cannot access the two links

e2e.ti.com/.../351308
e2e.ti.com/.../1253913

there shows up access denied.

Is there any documentation like an Errata for the chip/API/simplelink?

That would be very helpful in our development.

Kind Regards,

Matthias

Hi Matthias,

Those threads had almost the same info. So it's ok even if you don't go through it.

We normally put the known issues in the below link and you can also refer release notes

Thanks and Regards,

I'm trying to reset the cc3200 SOC and MCU with the following code:

sl_Stop(30);

Utils_TriggerHibCycle();

PRCMMCUReset(TRUE);

Is there something I'm missing? It usually works but not 100% of the time. Sometimes the MCU doesn't reset, just hangs.
