https://devzone.nordicsemi.com/f/nordic-q-a/75073/firmware-changes-when-moving-from-nrf52832-to-nrf52833Should a firmware written for nRF 52832 run smoothly on a nRF52833 if no changes in functionality are desired? If changes to the firmware are needed, which layers must be addressed?en-USTelligent Community 13Fri, 14 May 2021 12:48:02 GMThttps://devzone.nordicsemi.com/thread/309784?ContentTypeID=1Fri, 14 May 2021 12:48:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0130450f-00cf-43ee-af03-a362f2c69e25Marte Myrvold<p>Hi,</p> <p>The code itself should be very similar, but there are some changes and configurations.</p> <p>You should make sure that the pins used in the nRF52832 project can be used in an nRF52833 project as well. See the&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/pin.html?cp=4_1_0_6_0">pin assignment</a>&nbsp;om the product specification for more details.&nbsp;</p> <p>In addition to this, there are some changes necessary to make the project work on the different hardware. For this you can follow&nbsp;<a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/nrf52811_user_guide.html?cp=7_1_5_1_3#ug_52811_project">this guide</a>. This is for transferring a nRF52840 project to nRF52811, but the process will be similar. Just replace the mentions of 52811 with 52833 and change the maximum RAM and flash size to correspond to that of the nRF52833. You will also have to use another SoftDevice. See the <a href="https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52833/COMP/nrf52833/nRF52833_ic_rev_sdk_sd_comp_matrix.html">compatibility matrix</a>&nbsp;for information about&nbsp;which SoftDevices and SDKs are supported on the nRF52833.</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>
