nrfutil nrf52820

I want to ask the new nrfutil version 6.1.0 is support for NRF52820?  How to generate the setting.hex for NRF52820

Hi
you might want to have a look at the first line of the settings file which could look like this

:02000004000FEB

this means
:02    two bytes of content
0000  address of content (does not make sense for this line)
04   high word of address
000F  content
EB    checksum

in other words: these setting shall be written to 0x000F....
every line below will provide the lower 16 bit of the content address
the value should match the intended location of the bootloader settings according to the memory map for the specific device

@ Nordic staff:
please add the option NRF52820
> ....NRF52QFAB,it's working well
how should I know this? why should I guess? this cost me 3 hours of work :-(

You should try --family NRF52QFAB .Because this tag just for generate the start address  for setting.hex.
