DFU- OTA Build issues with Bl653dvk

[Shikamaru]

Hi,

I have a firmware (performing DFU over Bluetooth )that runs well on nRF52833 dev kit  and  for developing the DFU over BLE. I follow this tutorial

but , when same building for bl653dvk , we are getting below error. please suggest on this.

Hi

As I mentioned in my last reply, third party kits like the BL653 DVK tend to not include an external 32kHz crystal as these are an optional part of the nRF52 ref. design. If it's not included the best option is to use the internal RC oscillator, which requires the multithreading config to be enabled. I guess you have configured the RC oscillator somewhere in the project you flash onto the BL653 DVK, but not the Multithreading config.

Best regards,

Simon
