libqmi-devel Digest, Vol 77, Issue 3

This report is from quite some time ago but as I hit this issue when
working with libqmi recently, maybe some of my debugging can help anybody
else if they get this issue. In my case the upgrade is failing whenever I
am using a slow baud rate. Each time I tried to upgrade an MC7455 with a
connection using baud 9600 I would get this error. On a hunch I thought
that this may be related to the issue. I redirected the upgrade output to a
file and the upgrade worked fine, I sshed in and that worked fine also.
Another issue I noticed is that when upgrading is complete and the updater
is waiting on a reply using the cdc-wdm port, if the higher enumerated of
the two ports is used, the transactions will time out. For instance if the
modem comes back up with cdc-wdm0 and cdc-wdm1 then if cdc-wdm1 is used
this will happen 12 times and then the program will print an error also
(seen below):
[14 Jan 2019, 14:34:43] [Debug] [/dev/cdc-wdm1] sent generic request
(translated)...
<<<<<< QMUX:
<<<<<< length = 11
<<<<<< flags = 0x00
<<<<<< service = "ctl"
<<<<<< client = 0
<<<<<< QMI:
<<<<<< flags = "none"
<<<<<< transaction = 1
<<<<<< tlv_length = 0
<<<<<< message = "Sync" (0x0027)
[14 Jan 2019, 14:35:03] -Warning ** couldn't create DMS client after
upgrade: couldn't open QMI device: Transaction timed out
[14 Jan 2019, 14:35:03] -Error ** qmi_device_release_client: assertion
`QMI_IS_DEVICE (self)' failed
No functional error, the modem upgrades successfully, it just errors and
never returns to the linux prompt without user intervention. The lower
enumerated port works fine.
