Hi,

Can you provide some more info on how you have connected the device?

Hi,

the hardware connect as shown in the figure below:

Ubuntu 22.04.1

nRF Connect SDK v2.7.0

step 1: I open the application/asset_tracker_v2,

step2: click build

step3：click flash

Observing the serial port print log:

I don't know where the error occurred？

[JONATHAN LL]

can you try to recover your bord first?



Then when you do a build use the pristine build option


And then when you program click on the Erase and flash option. 



Regards,
Jonathan

Hi:

I followed the above steps, but it still doesn't solve the problem

[JONATHAN LL]

Have you done any changes to the project, like different boot address?

If so Please set the partition with the pm_static.yml file instead of the overly file. You can let the partition manager generate build/partitions.yml automatically, and duplicate and rename it to pm_static. Modify the partition in pm_static as you want, and then place it under the app folder

Hi:

I just received the development board, I didn't make any changes to the project.

[JONATHAN LL]

Try to update the SDK and update the toolchain and see if that helps. 

Could also try to update the board controller, https://infocenter.nordicsemi.com/topic/ug_trace_collector/UG/trace_collector/update_board_controller.html?cp=11_3_5_3_0 .


https://docs.nordicsemi.com/bundle/ncs-2.0.0/page/zephyr/boards/arm/nrf9160dk_nrf52840/doc/index.html 

When building for the DK revision 0.14.0 or later, you can use the following additional nodes (see Building for a board revision for information how to build for specific revisions of the board):

Devicetree node label	Analog switch name
nrf_interface_pin_9_routing	nRF_IF9_CTRL
io_expander_pins_routing	IO_EXP_EN
external_flash_pins_routing	EXT_MEM_CTRL

Sample should work out of the box with no changes at all.

Hi , but I fllow the quick start steps, it's successful,why?

[JONATHAN LL]

I am not sure what causes the issue that you are seeing. Have not seen this before. 

Maybe you can try to update VS code to see if it works. 

Or you can use the Programmer app if the flash function in VS code does not want to work. 

Maybe it is related to operating system and settings, it can be difficult to tell what caused the issue, and if it is a bug or not.
