[qmi-firmware-update] Flash modem with multiple FWs without resets

[Alexander Dydychkin]

Hi dear developers,
I am new to libqmi and want to flash multiple FWs with 1 time call of
qmi-firmware-update app (to eliminate resets).
I run the app like this:
qmi-firmware-update --update --ignore-version-errors -w /dev/cdc-wdm3
fws/50-SWI9X50C_01.08.04.00_VERIZON_002.015_002/SWI9X50C_01.08.04.00.cwe
fws/50-SWI9X50C_01.08.04.00_VERIZON_002.015_002/SWI9X50C_01.08.04.00_VERIZON_002.015_002.nvu
fws/50-SWI9X50C_01.09.04.00_DOCOMO_002.015_000/SWI9X50C_01.09.04.00.cwe
fws/50-SWI9X50C_01.09.04.00_DOCOMO_002.015_000/SWI9X50C_01.09.04.00_DOCOMO_002.015_000.nvu

If I understand correctly that is not supported because multiple nvu files
cannot be flashed at 1 time (cwe flashing works fine).

And here are some questions:
- Why multiple nvus cannot be flashed at 1 time?
- Maybe it can be patched? Can somebody give me advice on where to search?
I can try to patch the source code.

My main goal is to reduce the time of flashing while working with multiple
FWs.

P.S.
Connected email thread: "qmi-firmware-update with multiple NVU for Sierra
EM7411".

With best regards,
