Compatibility table for nRF51422

[Nestor Matas]

Is there any compatibility table for nRF51 series chips with revisions, softdevice versions and SDK versions?

I have some custom boards with a module that contains a nRF51422 CEAA A0 (0x0031) and although I can reprogram the softdevice downloading the S310 or the S210, I have issues when trying to run ANT examples from the 5.2.0 SDK. The issues include hardfaults that occur when opening the ANT channel.

Will I be able to use softdevice 310 if I go back to SDK 4.2.2,?

I'm using Keil 5.10, SDK 5.2.0, SD310 1.0.0

Hi

The CEAAA0 chip is preprogrammed with the S210 v2.0 and should be compatible with the nRF51422 SDK v4.4.2. Preprogrammed means that the softdevice can not be replaced or erased. In order to program a new S210/S310 softdevice, you need to get a hold of the latest version of the nRF51422, for CEAA it is the CEAAB0 chip.

Can you please confirm that the chip you are having is the CEAAA0, by reading the chip markings on the chip itself. If you can program the device it is the CEAAB0 chip, according to my cookbooks. Also, the former preprogrammed S210 softdevice had 40kB footprint while the new S210 v3.0.0 has a 48kB footprint.

It may well be possible that nRFgo Studio does not directly recognize the softdevice on the CEAA chip.

The former S210 softdevices (prior to v3.0.0) were preprogrammed in production to previous nRF51422 versions. S210 softdevices prior to version 3.0.0 were only available on the nRF51422 chip as preprogrammed.

We do not recommend to start new development with the CEAAA0 as there is currently a newer major release now available for the S210, i.e. v3.0.0.
