Running NRF52810 on NRF52811

user18378

Hi,

I already have a product which is running on NRF52810 (SDK S112)

Since the lack of CPU worldwide problem i found a stock of NRF52811.

I saw it's hardware is pin compatible.

But is it possible to run the same software (which was developed for 810) without changes on the new CPU (811).

I also need to prepare DFU file for firmware upgrade and i don't know on which CPU (810/811) will be there.....is it possible ?!

B.R,

Yuval.

    Hi,

    The nRF52811 and nRF52810 is very similar but with minor differences, the nRF52811 has two instances of SPIM and a better radio that supports more features such as long range. It also has a bigger MAXCNT which means that it can transfer larger data bytes at a time.  If you take this into consideration then it should be ok.

    regards

    Thanks for the answer but i was asking something different.

    I asked if is it possible to take my software that was written on 810 and fuse it as is on 811 ?!  will it work ?!

    Hi,

    Yes it should be possible to flash it, and most probably it will run if you're not using nRF52811 specific features. But this isn't something that we recommend as we want the customer to use the correct start and system files. These files includes the correct errata's for the specific chip.
