nRF52833 and nRF52810 chip support

[Lawrence Kincheloe]

Hi,

I've got a new product I'm developing and I need support for either nRF52810 or nRF52833.

I know that nRF52810 is no longer directly supported, and there isn't any mention of support for nRF52833 or the nRF53 series of upcoming Nordic chips. 

Just wanted to see if anyone else has started porting, before I jump off the deep end. 

Regards,

Lawrence

Hi Lawrence!

The nRF52810 is really low on memory (24 KB) which makes it less interesting. The nRF53 is definitely interesting, but a bit more complicated and longer term. I think there are some people working on it at Stanford?

The nRF52833 though, should be pretty straightforward to support. In fact, we just got a pull request for it today! https://github.com/tock/tock/pull/2255

Thanks
Branden Ghena

Yes, Tyler (with Michaela and Hudson sometimes assisting) is porting Tock to the nRF53. We have the main core booting and can do secure world/supervisor, and can do UART, Alarm, I think GPIO. Current work is on getting the radio core up and running too. We are using it as a combination of exploring TrustZoneM, multicore Tock and remote system call invocation.
