Relatively new EM7565, purchased through Future (authorized dealer), operational on as-delivered
Revision: SWI9X50C_01.05.03.00 23e1da jenkins 2018/03/28 22:42:08
As I was having problems getting a qmicli script to be able to retrieve both the IPv4 and IPv6 addresses when in raw-ip mode (I can get one or the other, but not both, subject of a later post, perhaps), I tried upgrading the firmware.
TL;DR
In short, neither the “full” or the “lite” SDK’s tool seem able to add/upgrade firmware, only ending up with the original firmware showing in memory. I’ve tried the full SDK, with and without the qmiserial and qmi_wwan kernel modules loaded. I have moved the modem, attached through a USB housing, to a USB 2.0 port on the machine. Machine is running Debian 9.5 “stretch”, fully patched. Hardware is an AMD Ryzen 5 2600X on a Asus ROG Strix B450-F Gaming motherboard, with no history of any USB issues.
Suggestions or requests for additional information, debug output, all welcome!
Firmware and SDK were obtained directly from the Sierra Wireless site, https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages/ and https://source.sierrawireless.com/resources/airprime/software/linux-qmi-sdk-software-latest/
I did not see any MD5/SHA checksums available to confirm the integrity of the downloads.

I have re-downloaded the firmware and the SHA256 is the same.
jeff@deb-devel:~/Downloads/sierra-wireless$ ls -l SWI9X50C_01.07.02.00/
total 72677

In some cases, the update appeared to “take” very quickly (including the first time), indicating success, contrary to the Appendix A: Firmware Upgrade Instructions from Release 9 and older information. In other cases, after the modem switched to bulk mode, it would spit out periods for minutes or hours, with no apparent progress.
First attempt

I do have a set of full logs, including output of fwdldhostx86_64 interspersed with the syslog entries. A section that caught my eye because of the two errors around malformed XML, including ERROR: XML not formed correctly. Expected a < character at loc 0 similar to that found in the output of the “lite” run:

Rebooting the module
I found a post here suggesting https://github.com/danielewood/sierra-wireless-modems/blob/master/Sierra-Linux-QMI-SDK.md#flash-using-sierra-wireless-linux-flashing-tool-fwdwl-lite as a suitable reference for flashing. From that description I created the “lite script”, adding --dmreset as suggested to resolve the initial Error in modem crash state checking!error code = 103 condition.
The “lite script” based on the referenced github instructions
#!/bin/sh
devpath=`ls /dev | grep -i -E 'cdc-wdm|qcqmi'`
devtype=`expr "$devpath" : '\(cdc-wdm\|qcqmi\)[0-9]$'`
case $devtype in
cdc-wdm) devtype="MBIM" ;;
qcqmi) devtype="QMI" ;;
*) printf "Unknown Device Type = $devtype\r\nDevice Path = /dev/$devpath\r\n"; exit
esac
printf "Device Type = $devtype\r\nDevice Path = /dev/$devpath\r\n"
./fwdwl-litehostx86_64 \
--devmode $devtype \
--devpath /dev/$devpath \
--modelfamily 4 \
--logfile "fwdwl-lite-$devpath.log" \
-e 1 \
--fwpath "./swi_fwlatest/" \
--dmreset
Output of the “lite script”
