Porting from NRF52840 to NRF52832

[Srinivas V]

Hi Team,

We are porting from NRF52840 to NRF52832, what porting steps we need to take care for this in terms of,

  1, In 52840 we have used the CRYPTOCELL — ARM TrustZone CryptoCell 310 is not there NRF52832 IC, for this is there any other alternative Hardware Engine.

  2. Soft Device point of view for 52840 we have used the S140 and for 52832 we are going to use S132, in this regard is there any modifications we need take care for BLE and other peripherals.

3. what is the difference between nrf and nrfx drivers which are in drivers folder.

4.Is there any other drivers and config file settings we need to look into to modify for NRF52832 Device if we are going to use the same SDK version for both likeV16.0

Regards,

The easiest way is probably to start with a basic example from the SDK for the nRF52832.

This will give you a known-working starting point - so covers questions 2, 3 & 4.

Then merge your application stuff into this.

If you originally started your nRF52840 from an SDK example, then simply choose the nRF52832 version of that same example.

What ever is, it's exactly the same whether you use nRF52840 or nRF52832 - so shouldn't be a worry.

Hi Aweneil,

Thanks for your reply.

We will start with ble_peripheral example only, but if you know any known things like "Crypto Cell" not supporting in NRF52832 device, like that if we have any differences , those are very helpful to us while porting.

Any porting exercise requires you to do a thorough study of the "original" and "destination" chips - so see the differences.

If the "destination" chip doesn't have hardware support for a required feature, you have 2 choices:

1. Implement it in software;
2. Add external hardware.
