EM7565 firmware upgrade does not work

IoT Modules MC/EM Series
1

Hi,

I am trying to update our EM7565 card to the latest firmware, but it seems the updater wont find or recognize the card:

When I try with the FDT-Tool, the device is found and the flashing seems to be working, but at the end the firmware download fails:

The OS is Win7 64bit Pro, the latest Sierra drivers are installed and working, the modem, mbim, serial DM and serial NMEA ports are present, and the modem AT interface also works.

An interesting thing is that Skylight is also not detecting the card.

Any ideas why can this be?

You need to enable the RMNET in AT!USBCOMP.
what is the return of the following?

AT!ENTERCND=“A710”
AT!USBCOMP?
AT!USBCOMP=?

3 
AT!USBCOMP?
Config Index: 1
Config Type:  3 (Generic)
Interface bitmask: 0000100D (diag,nmea,modem,mbim)

OK
AT!USBCOMP=?
!USBCOMP:
AT!USBCOMP=<Config Index>,<Config Type>,<Interface bitmask>
  <Config Index>      - configuration index to which the composition applies, should be 1

  <Config Type>       - 1:MBIM USBIF, 2:PCIE USBIF, 3:Legacy-Generic, 4:RNDIS

  <Interface bitmask> - DIAG     - 0x00000001,
                        NMEA     - 0x00000004,
                        MODEM    - 0x00000008,
                        RMNET0   - 0x00000100,
                        MBIM     - 0x00001000,
  e.g.
  10D  - diag, nmea, modem, rmnet interfaces enabled
  1009 - diag, modem, mbim interfaces enabled

  The default configuration is:
  at!usbcomp=1,3,10F

OK

not sure if it helps in FDT or Skylight
you can have a try:

AT!ENTERCND=“A710”
AT!USBCOMP=1,3,10D
AT!RESET

Thanks for your help, it solved both the Skylight and firmware upgrade issues, now the unit is on the latest version.

One more question though: is there a newer version of Skylight compared to the one on the Sierra support site from 2018?

I think that is the latest one.
