not able to debug nRF9160 DK getting error "Failed to download application Generic error"

[praveenpalaparthi]

Hi,

My working environment:

NCS folder Tag:v1.2.0

J-Link version : v6.62a

SES version:4.42a

test sample code:\NCS\nrf\samples\nrf9160\cloud_client

nrf connect environment option:

When I tried to debug by pressing F5, I am getting error as

"Failed to download application Generic error,Please check J-link and target connection"

Not able to enter into debug mode.Can you please help how to debug a code.

Hi Praveen,
I was able to reproduce this issue, there seem to be some issues that we need to investigate.

However, please try out this workaround:

Please try to go in SES "Target"--> "Disconnect".

Open CMD and use the command :

nrfjprog -e

Then in SES, "Build"--> "Build and Debug"

(if a question pops up to rebuild, please press yes)

Then you should be able to debug.

Hi Martin, your solution worked but apparently we need to do "nrfjprog -e" before every single time programming via SES.

Is there going to be an update for SES or NRF Command Line Tools to solve the issue?

Hi Gurkan,

This bug has been reported internally, and we are working on a solution.
Most likely we will release an updated version of SES.
