It looks like the kernal is damaged.

How do I reload firmware/kernel?

It seems that alot of the file required are missing.

M14A2A_driver_x.x.x  https://s3-us-west-2.amazonaws.com/starterkit-assets/M14A2A_driver_1.0.2...

Firmware update application: - https://s3-us-west-2.amazonaws.com/starterkit-assets/WNCCM_1.0.9.zip

LTE-M firmware:: https://s3-us-west-2.amazonaws.com/starterkit-assets/NQ_MPSS_IMA3_v10.58...

Is there a location where everything is? Do I load firmware or os or both?

Thank 

Peter

The M14A2A contains no kernel,, it is a slave device only. Not sure what you are trying to do.

I'm new to this type of device. I am going to try the SIM7XXX LTE-M (Cat-M1)(eMTC)
NB-IoT (Cat-NB1) development devices. Thanks for your response.
