Fdt2 programming of Wp7702

IoT Modules WP Series
1

We appear to be having similar issues as to what is happening in this thread: FDT continuously fails checking firmware update status (FX30s) when attempting to program our boards using the fdt2 tool.
It starts up OK, and does flash the image correctly, however after flashing the image it gets stuck on the Awaiting adapter ... step before giving an error. I do however see both the DM port and the application UART come back online (as well as our program start up correctly and connect to the internet).

This happens both when programming an SPK with the legato system and everything in it, as well as with the CWE with just our application. Here the logs of the fdt2 tool:
fdt2 - cwe - 2021-04-22_12.56.14.601.txt (140.4 KB)
fdt2 - spk - 2021-04-22_13.06.20.666.txt (482.3 KB)

What are some steps we can take to find out what is happening with this? as we would like to use this for production.

Hi @shommersom

After the module come back, have you check the module information? Is it match with spk or cwe file information?
You can try to below steps:

  1. Check RMNET0 on module, If it disable then enable it. you can follow steps:
    AT!ENTERCND=“A710”
    Enable RMNET0 by AT!USBCOMP=1,1,8010D
    You can refer to !USBCOMP command on the “AirPrime WP AT Command Reference” for more detail.
  2. Check Cellular network on Windows PC (Setting → Ethernet → Change Adaptor Option), make sure that the Cellular network was enabled.

Check again and share your result.

Thanks.

It looks like the SPK/CWE is programmed in correctly if i’m looking at the version information. The device is not meant to be a modem so we have disabled the rmnet part. Is that required to be on for using the fdt2 application?

Hi @shommersom

From the Sierra developer team, FDT checks FW update status via QMI interface, that means FDT only cares about network adapter interface (not AT or DM). So, The RMNET must be enable on the device.

Thanks.
