Hello Carl,

As we are in the middle of summer vacation period we have fewer resources to answer. Please open a new ticket with your question.

Hello, thanks,

Can we reopen this case?

In nRF5340 project, I have two projects, one is Net core, the other is app core. I use SEGGER to build these two projects, flash the images into the development board. Net core is a elf file and app core is a hex file. There is no problem.

Now I want to send the files to my friends and ask them to flash it in to their dev board. They can use nRF connect Programmer to load the hex file and write it into the board, but the programmer does not support to write elf file. What should I do ?

It seems that I have to use some tools to build the elf file and hex file into one big hex file?

Thanks,

Carl.

Hello Carl,

I'm not sure I understand. The hex file is generated by building a project. Why do you need to read the nRF5340 to generate a file?

Kind regards,
