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.

Hi,

1. Have you manged to get serial output with another sample?
2. Have you changed anything in the sample code or configuration files?

Best regards,
Benjamin

Hi Benjamin,

Im sorry not, i didnt change anything.

I also tried with 3.0.1 SDK  version as below but same behaviour .

The "merged.hex " file is generated but it doesnt start directly after Flashing from Vscode.

If , again, I flash the code by using nrF programmer it works and I see in the VScode terminal window the UART strings:

[Benjamin]

You can see serial logs in VSCode when you flash the device using nRF Programmer,
but you do not see any logs when flashing the device directly from VSCode?

Is that correct?

Hi Benjamin,

I can confirm. In addition , after I flash with nrF Programmer and I come back to VS code I can even debug the code. So its strange for me even if for know I can of course do:

1. build app with vscode

2. flash it with programmer

3. switch back to vscode and debug it

Thanks
