Hi ivnn,

Have you followed the instruction here on how to do a DFU update? You must test with a "with serial" example first before you can test with "no_serial"

To be able to test with a "no_serial" you would need to have at least a "with serial" to connect to PC to receive the image. The node connected to UART to PC will act as the bridge to spread the image out to the mesh network and update those "no_serial" nodes.

Note that you can't use nRF Connect to do DFU update, you need to use nrfutil tool on PC to do it.

The log note about adjusting ram is just for optimizing the RAM setting for application, it's not related to DFU update.
