Pyocd not flashing nrf52833

[Nilon123456789]

I'm trying to flash the zephyr.hex but it's only erasing the board.

pyocd flash zephyr.hex --target nrf52833

I'm I doing something wrong?

pyocd --version
0.36.0

Programmer : Atmel Corp. Atmel-ICE CMSIS-DAP
I've plugged the vRef, GND, SWIO, SWCLK

[Nilon123456789]

I'm able to get RTT logs with the version 0.34.3. However, I still can not flash.

Have you tried doing a mass erase first? pyocd erase --mass

[Nilon123456789]

Here is the output of the pyocd erase --mass followed by the output of the flash.
