How to write the bootloader back to nRF52840 Dongle ?

hi,

I have accidentally selected "Erase All" under the Segger Embedded Studio, now my nRF52840 Dongle unable to show its USB port under Windows 10 Device Manager anymore.

How to resolve this issues and where to get the right bootloader image for nRF52840, as the nRF52840 Dongle unable to report its serial port, Segger J-Link was unable to connect.

Please advise.

thx but Windows is unable to detect the serial port of nRF52840 dongle ( i think the bootloader is erased ) and J-Link was unable to connect as well, how to write the .HEX then ?

Normally if erased, you should be able to reflash the hex with J-Link or other JTag via the SWD connector. If not you may have a dead board

just to check, if the nRF52840 Dongle is erased, do I need to powered it via USB still ?

or with SWDIO and SWDCLK connected to J-Link will do as I am new to Nordic nRF52840, normally using SWD interface there is VCC pin but in this case it is needed for nRF52840 Dongle ?

you still need to power it via usb. SWD does not provide power.

ic, thanks for sharing, I am not sure why a single erase can damage the board ( eg. using clone J-Link ? ), but the VDD of nRF52840 did output 1.8V still.

The nRF Connect is no longer reporting the device as "F62B9XXXXXXX" but "0042949672XX" instead, when selected the "0042949672XX", the Device memory layout just keep loading, nothing loaded.

Try to use a nrfjprog instead of nrfconnect. nrfconnect is not reliable using jlink when bootloader is erased.

I am using genuine Segger J-Link Home to connect the SWDIO and SWCLK pins of the nRF52840 Dongle, either user USB power or soldered SB1 ( with SB2 broken ) with 3.3V supply to VDD, J-LINK VREF to 3.3V

Please advise.
