Blink project not working . nrf52833dk

[NCKGTW]

Dear staff,

Im new to Nordic chip  so please forgive us

We bought 2 nrf52833DK and we started by following your tutorial on vscode (nRF Connect for VS Code - Tutorials - nordicsemi.com):

1. installed VScode extension
2. Installed toolchain to last version
3. installed SDK to las version
4. Copied the Blink project as in the tutorial
5. built a configuration

This is our build configuration

After building and flashing the board We dont see any LED of the ones in the DK blinking .

This is our "connected devices" section 

Even if we connect on both COM we dont see any string 

The only one wich seems to be ok is the JLINK

I post the "Flash" output which is ok

We also tried to reset the board from IF BOOT/RESET button but nothing happens.

Could you please support us?

We need to develop some ble app with Zephyr so its important to have a stable IDE for programming and debugging.

Thanks a lot.

Hi just to give you un update: 

• the project was copied from the "zephyr/sample/basic/blinky_pwm

In order to check if all DKand HW is ok  I performed:

• opened the nrf Connect Programmer like below:

• load the hex file as below (blinky_pca10100e):

• did a "Erase/Write"

All led are correctly blinking so the whole HW (interface MCU+nrf52833) is OK.
