Thanks for your support.

We were able to build the code for a custom board and it flashed. The code is up and running on our custom board.

We tried 2 configurations as below.

- Created the files for nRF52833-QIAA and edited the name in all the files to nRF52833-QDAA.

- Created the files for nRF52820-QDAA and edited the name in all the files to nRF52833-QDAA.

In both the custom configurations it is working.

I had to ask internally, it should be fine to use the QIAA.

Since you baed your board on the DK you will need turn off the DCDC which is enabled by the defconfig for nRF52833dk_nRF52833. This is only valid if you have not included the coils that the DK. this can be done with the following KCONFIG

CONFIG_BOARD_ENABLE_DCDC=n
CONFIG_BOARD_ENABLE_DCDC_HV=n

Runar,

2. We are working on it. In the SoC selection, the only option available for nRF52833 is QIAA. But in our case it is QDAA. How do I select this?

3. Yes, we did it and tested. But no change.

- Are you trying to build the configuration for our requirement?

Hi and thanks for the update

2. The recommended way to to create a custom board since you are using a custom board and use it as a build target.

3. You can set it in the prj.conf

For the rest I would start with following the the exercise and adapt it to your need and if it does not work we can take a new look at it

Hi Runar,

Thanks for your support.

1. Yes, it is nRF Connect SDK with VS code environment.

2. We are using the nRF52833dk_nRF52833 build configuration. Do we need to use any other configuration to flash the external boards?

3. Where do I can set the LF clock source? We didn't enable any specific clock source in the code.

We tried this but no use.

- The design is not that much customized. We just followed the schematic which I shared here.

Please advise, are there any changes needed in the configuration of 73 pin to 40 pin configuration in the build?

Do you have any other suggestions?

We are looking into the guide "how to add custom boards ".

I have a private case with Blaze regarding a similar issue.

1. Which SDK are you using. I expect NCS

2. What build target did you use when you build your application? If you build of the DK it would add some additional Kconfigs which you might have not included in your custom boards.

3. Which source do you use for LF clock? You can try to add the following KConfig and see if it helps

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

We have an excellent guide here on how to add custom boards
