MC7455 firmware update fails - error 6

IoT Modules MC/EM Series
1

I’m trying to update firmware on some MC7455 - 1103789 modems.
Modems came with 2.24 firmware.
I can update them successfully on a linux device to SWI9X30C_02.32.11.00 (AT&T specific) firmware without issue.

I tried to update them to generic firmware SWI9X30C_02.33.03.00 on the same device and the same procedure but get an error:

I can’t find any info on the Sierra site about this error? Any suggestions on other methods I could try or info I could gather?

I don’t think you should use “-d 9x15” for mc7455

3

@jyijyi are you suggesting this could be the problem and I should exclude that part and use this?

./fwdldarm -s /opt/bin/slqssdk -p /opt/generic

I think mc7455 is using 9x30 chipset

BTW, is the FW update successful? (but just Failed to get firmware details after download)

The firmware update fails, checking the status after the error and it is still running the factory loaded 2.24 firmware.
I tried with the previous generic firmware as well - SWI9X30C_02.32.11.00_Generic_002.064_000, and the failure is the same.
So generic fails and AT&T specific works at 2.32 level firmware.

how about using Windows EXE file

I’ll try to get an enclosure to connect to a windows pc and try.
