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,
Carl Richard
