Nrfjprog not working after flashing Zephyr blinky example

Question

Hi. 
 I'm trying to program a custom NRF52833 board with the blinky example from zephyr (NCS 2.4.2, VS Code). After flashing, the program freezes most of the time (I say most, cause It happend 2 times, when I connect the RTT that it runs). The problem is afterwards, that I cannot reflash it, It somehow bricks itself. 
 I tried it with nrfjprog and I'm getting the following errors:

nrf52 --eraseall --log
[error] [ Client] - Encountered error -102: Command read_device_info executed for 174 milliseconds with result -102
[error] [ Worker] - An unknown error.
[error] [ Client] - Encountered error -102: Command read_memory_descriptors executed for 75 milliseconds with result -102
Failed to read device memories.[error] [ Worker] - An unknown error.

ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.

If I run "nrfjprog -f NRF52 --recover" and turn on the device at the same time, the recovery works. But it takes a few tries to get the right timing. But then, after one flash it's gone. 
 I'm sure it has something to do with the configuration and the zephyr - blinky example. I have a old nrf5 SDK program which runs fine on the board. 
 As JLINK I'm using a NRF52840DK

Hello, 
 Does your board have the optional DCDC inductors? If not, please ensure you disable the DCDC regulator in your project. By default, it's enabled in the nrf52833 DK board file here: https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf52833dk_nrf52833/Kconfig . 
 Best regards, 
 Vidar
