Modem shell hex file is not valid

[VishalGujela]

Hi 

We are trying to configure Nordic UE (NRF9160) at our local setup. In order to flash software we performed following steps:

1. We used 'carrier_deploy_e7f4d5d4-f607-43a6-b383-cfdb6d725c82.zip' to flash SW in secure boot mode.
2. We used 'mosh_nrf9160dk_modem_uart_trace_v104.hex' to install modem shell application

      

Can you suggest what step is wrong at our end. If we are using wrong firmware files, then can you please share the required one.

We took reference from file 'nRF9160_External_Test_tools_Flashing_and_USB_Modem_Tracing.pdf' (attaching for reference) to flash the SW in Nordic UE..

Thanks.

Hello Vishal,

now I messed things up a little bit. My very apologies for that!

Of course, there is an MCUboot image available, located in  ../img_fota_dfu_hex/debugthingy91_asset_tracker_debug_nbiot_legacy_pco_2021-06-28_7a076c22.hex.

I set my Thingy91 into boot mode, choose the Thingy:91 in the Programmer Tool and selected the above-mentioned file:

Initiated the download by pressing the “Write” button

Download started.

And finished successfully.

In LTE Link Monitor I can confirm that the firmware image is starting up.

By the way: there is a Modem Shell application available now, but we do not provide an official application image for that. If you would like, I can prepare one for you Thingy:91.

Regards,

Markus

Yes , please provide that application.

I guess that might help us out.
