Erratum [220] in SoftDevice S132 V7.2.0

[Pascal Künzi]

Hi all,

In the nRF52832 erratasheet, for erratum [220] it states:

"SoftDevice v7.0.1 includes an alternative workaround which does not support FPU being enabled."

Am I correct in assuming, that this alternative workaround is not included in V7.2.0?

Thus, I have to implement the workaround as shown in the erratasheet when using the SoftDevice V7.2.0?

Thank you in advance!

Best regards,

Pascal

Hi Pascal,

Am I correct in assuming, that this alternative workaround is not included in V7.2.0?

No. SoftDevices version 7.2.0 use the same workaround for erratum 220 as version 7.0.1.

Thus, I have to implement the workaround as shown in the erratasheet when using the SoftDevice V7.2.0?

No. And you would not have to implement it if using SoftDevice version 8 either, as that has the other workaround implemented.

This may not be relevant for you, but if you need to use the FPU and a SoftDevice version 7.0.1 or 7.2.0, then that is possible to disabling stacking of FPU registers.

Hi Einar,

That's good to know.

Thanks a lot for the quick response and clarifying this for me.
