Can't I use Arduino with nrf52840 revison 3?

[hmihmi]

I made a custom board, uploaded the Arduino bootloader and was flashing the firmware with Arduino
I used it without any problem with revision 2
But when I use revision 3 chip on the same board, the board does not work
USB uf2 bootloader does not work either
Is there a way to use nrf52840 revision 3 with Arduino?

Hi, 

I have no knowledge of the Arduino bootloader and USB uf2 bootloader. It seems they do not support nrf52840 revision 3. See IN-141.

Please seek help from the Arduino Help Center or Arduino Forum.
