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,

could you please flash the image:

img_fota_dfu_hex/debug/thingy91_asset_tracker_debug_nbiot_legacy_pco_2021-06-28_7a076c22.hex

and check if that makes any difference?

Regards,

Markus
