Load NRF52833-DK code on custom NRF52820

[PIRHeisenberg]

Hi everyone,

I have designed a project based on the Radio test example, in the Nordic SDK. After programming all my code on the NRF52833 DK (PCA10100), i decided to design my own pcb and load it with the NRF-DK. As Chip i used the NRF52820. So far so good. I am now running into some compatability issues which im not shure how to fix.

It has probably to do with some config files which im not aware of how to edit.

Please help, the deadline is comming closer.

Best regards Maikel

Hello Maikel

Please check out the developing for nRF52820 user guide on the Infocenter, and specifically the section on "Transferring the project to nRF52820 hardware" which will explain what you need to modify in your project to make it run on the nRF52820.

Best regards,

Simon

Hi Simonr, 

Thanks for your help, you set me on the right way. I have now Created a new Project based on the NRF52820 chip. Now i am running into some compatability issues. I probably have to change some things in the flashplacement file. but im not shure.
