Hi,
I've recently picked up a Quectel EC20 after hearing about the
AT+QLINUXCMD command. While looking around, I somehow managed to get my
device stuck in QDL mode where I have only one ttyUSB available and
lsusb shows the device in QDL Mode.
I have the flashing utility but I don't have an image at hand. Could
anyone send it to me or let me know where I can get it? While searching
I saw ftp://ftp2.quectel.com but that has the kernel source rather than
what I'm looking for,
Thanks.
Hi,
just FYI, I've been told recently, that SIMCom also uses MDM9225 in their
SIM72xx (miniPCIe) and MDM9215 in SIM7100x (SMT format) products.
So I've updated wiki with some basic details at
http://osmocom.org/projects/quectel-modems/wiki/SIMCom

Hi all,
the ME906v is a Linux-running Qualcomm based modem, which has been first
published about at DEFCON 23
(https://media.defcon.org/DEF%20CON%2023/DEF%20CON%2023%20presentations/DEFC…)
It is EOL by now (Huawei probably wants to use HiSilicon these days
rather than Qualcomm) but can be found rather inexpensively from
refurbished suppliers like http://www.minipc.de/de/catalog/il/978
Unfortunately it's M.2 / NGFF and not mPCIe, so it cannot be used in
most embedded devices (PC-Engines, Soekris, ...) or the Osmocom
mPCIE-breakout board.
I have just added some information to our wiki at
https://osmocom.org/projects/quectel-modems/wiki/Huawei_ME906v and
https://osmocom.org/projects/quectel-modems/wiki/Huawei_ME906v_adb
Summary:
* they don't really use the Linux for anything. Not even
QCMAP_ConenctionManager running
* not many HUAWEI modifications recognizable on the Linux side
* no fancy FOTA updates or AT+QLINUXCMD equivalents
* DIAG is present by default
* ADB can be enabled, but requires serial console soldering at least
once :/
Would be nice to find a way to enable adb without having to solder.
I'm still working with Huawei to release the related complete and
corresponding source code under the GPL.
Regards,
Harald

Hi.
Would be nice to add osmo-qcdiag to the list of projects checked by
https://scan.coverity.com/projects/osmocom?tab=overview
Maybe to https://gerrit.osmocom.org/ too to facilitate contributions via
the same process used by other Osmocom projects.

I think it is simply the fact that (at least) for the Linux on the Cortex-A5 it
doesn't make any difference whether it's running on a 9615 or a 9215.
The difference is presumably primarily in the cellular radio interface
and possibly DSP capacity? From the few publicly available information
the 9615 adds Ev-DO (3GPP2) capability, while the 9215 is GSM/UMTS/LTE
(3GPP) only?
btw: I just created a new mailing list for any future public discussion
on the Qualcomm Linux based cellular modems, see
qc-linux-modems(a)lists.osmocom.org and/or
https://lists.osmocom.org/mailman/listinfo/qc-linux-modems
