NRF52832 chip revision

[John Lee]

I heard that nrf52832 rev3 has been released.
Our product is using nrf52832 rev2, nrf SDK 15.3.
If we change the chip to rev3, can we use the firmware without modification?

If it's not available, please tell me how to do the least firmware modification.
We want to avoid changing the SDK version as much as possible because it takes a lot of time and money for licensing our products.

Yes, you can use the same firmware if you don't use the approtect feature.

But, I recommend you to contact the Nordic distributor that you already have a connection.

They are going to guide you on how to use the updated IC and what is required for production.

or you can refer to this page.

Thanks for your reply.
I understood as below.

1. If do not use the app protect feature, can use the existing firmware as it is.
2. To use the app protect feature, MDK must be upgraded to 8.40.2 or higher.

We are considering applying the app protect feature.
Therefore, MDK version upgrade is required.
Can you tell me how to upgrade the MDK version?

[Eugene Yu]

The easiest way is just using the latest nRF5 SDK.

Because the nRF5 SDK v17.1.0 already includes the APProtect updates.

If you want to update the MDK only, you can take the code from the latest MDK depending on the compiler you are using.
