Errata 172

[Roei]

Hi,

I'm trying to figure out if my device is suffering from errata 172.

* How can I know if I'm using Ble_LR125Kbit or Ble_LR500Kbit?
* I'm trying to use the function bool enable_errata_172 (void). Do you have any example for that?

Thanks!

Hi,

There seems to be a typo in the document, the correct function to call is enable_anomaly_172().

Thanks!

What about the kit? How can I know which one I use?

[Jared]

You could use nrfjprog command memrd and read the MODE register.

Thanks!

But it's still not clear from the document - which files should I include in order to use this function? Do you have any example?

[Roei]

Is there any example for how to use the nrfjprog command in order to read memory?

Hi,

You can look at ble_dtm.c which is used in the dtm example in the SDK. There it's checked if the workaround for nRF52840 Anomaly 172 should be enabled or not:

                    if ((*(volatile uint32_t *)0x40001788) == 0)
                    {
                        anomaly_172_wa_enabled = true;
                    }

nrfjprog command for reading MODE register:

nrfjprog --memrd 0x40001510
