 I am using nRF52840 dongle. To program this dongle an nRF connect programmer is used. Unfortunately erase button of nRF connect programmer is always disabled?Is it possible to enable it? Thanks for your time?

Hi, 
 
 Please click "Write" to write the firmware to the dongle. 
 You cannot do an erase all via nRF Connect for the Desktop programmer app when using the dongle. The reason for doing this is that if someone erases the bootloader, it would not be possible to program any new applications on the dongle anymore. The reason that nrfjprog does not work with the dongle is that there is no built-in J-Link on the 52840 dongle. I would recommend reading this blog post in detail.
