nrf52 errata and developer kits

[pixiedust]

Hi,

I'm going through the errata and a few of them look serious that the developer kit might be useless for some of us if we want to use it for any realistic testing (I've got a few to evaluate, NRF52832 QFAAAA 1509AA)

Things that I'm interested in especially are non-functional PWM, RTC issues and NVMC issues.

Is there going to be some software workaround or would I have to wait for a newer revision of the hardware ?

Also if these are hardware issues, could we get updated IC (I can try reworking the boards) or replacement dev kits ?

Thanks

The errata give software workarounds for those things which have them, and the startup file pokes things into various registers to get those workaround going. However the things which are fully non-functional are fully non-functional. So if you really want to test PWM, this board isn't going to be totally useful. There's a lot of new stuff which is working, enough to make the preview valuable, but yes there's a lot which isn't, not unusual for an engineering early release.

I've seen no comment that there will be any interim upgraded hardware release, my expectation is that we're waiting until the end of the year for the first production batch of chips, that's what I've been my working assumption at least. And I don't expect them to be totally free of anomalies either.

It's a chip, it's pin compatible when the new release comes out, you can certainly buy one and rework the board, but I don't think it's going to be for a while.
