Thingy 91 debug using J link Edu

Rkidechaa

Hi,

I tried to burn the hello world sample code into thingy 91 using segger and J link Edu.
After configuring Termite it did not show anything.
And now LEDs are not blinking and nothing happening.
can you guide, what to do? or how to reset thingy 91?
while connecting again to segger showing below issue
Also, it is not going under the MCU boot mode.
With Regards,

    Hello, Rahul!

    Thank you for reaching out! Could you first state what Thingy:91 version you have and wheter or not you are using the Toolchain manager?

    Secondly, you are flashing the Zephyr hello_world sample, correct? There are not supposed to be any blinking LEDs when using that sample, and for MCU boot to function with the sample it must be added in prj.conf like this:

    CONFIG_MCUBOOT=y

    Lastly, I see that you are building for the "board name" thingy91_nrf9160, use thingy91_nrf9160ns instead. 

    Hope this helps!

    Best regards,

    Hello, CARL!!

    Could you first state what Thingy:91 version you have and whether or not you are using the Toolchain manager?
    Ans: tried to debug thingy 91 using j link Edu using SWD pins. 

    Secondly, you are flashing the Zephyr hello_world sample, correct? There are not supposed to be any blinking LEDs when using that sample, and for MCU boot to function with the sample it must be added in prj.conf like this
    CONFIG_MCUBOOT=y

    Ans:  Yes. I have created the prj.conf file as per the tutorial.
    Lastly, I see that you are building for the "board name" thingy91_nrf9160, use thingy91_nrf9160ns instead.
    Ans:  Got it I have downloaded the board file for thingy 91 and made the changes as you said.
    I Made all changes but I am still getting the same error that I informed you of at the beginning. I have done the research for the error and that could be one possibility that space between my user name. which are not allowing segger to connect path. I tried to change the user name folder but I guess now I can not change the same. (suggest to me how to solve this problem).
    To avoid the user name problem I used another PC and did the step shown in the tutorial. after setting the cmakelist.txt, Board directory, board name, and build directory when I click on the OK button segger was getting hang. (Tried 3 times and getting the same error)
    Do you have any videos tutorial which can show the step clearly?
    also to check the output do we need to connect more cable to the micro USB connector or just j-link Edu cable is sufficient?
    Thanks,

    Hi again, Rahul.

    Thank you for the response. What version of the Thingy:91 are you using?

    This is most likely correct! Changing the username and updating the path correctly can be a bit of a hassle, but Microsoft have described the approach here. Anyway, what kind of hang/error did you get on the other PC? Could you provide some screenshots/logs? 

    We do not have any video tutorial, but we provide a quite extensive guide on getting started with the Thingy:91. It also describes how you can setup projects in SES.

    Most samples are configured for output over UART, which will require a micro-usb to be able to display it in the terminal. Alternatively the sample can be configured to use RTT. The output from the debugger will then be available with the Segger RTT Viewer.

    Hello Carl,

    Now to avoid all the problems what I have done is created a new account with just a name and tried to build and flash the hello program using j link Edu. 

    we tried 1st time everything worked well but we were not able to see the output on the terminal. So we tried to flash it again but now, what is happening that when I open segger with toolchain manager software was getting hang not allowing to anything?  

    Also showing below error everytime when I click on open IDE.

    Now when clicking on Yes to all or No to all. software is getting the hang (while j link Edu is connected)

    Another thing is that now when I tried to load the pre-compiled Hex file it was not going under the MCU mode. (I know how to set in MCU mode)

    Questions:

    might be earlier we have done some mistake while flashing the hello program which led to any failure of the thingy:91?

    can we reset thingy 91 OR clear the flash memory?

    I am enclosing the photos of physical connection pf thingy 91 with PC using j link Edu.( Let me know if you find any problem in connection)

    With regards,

    Rahul Kidecha
