Quectel EC20EQAR02A08E2G FW Image
by Can Selcik 20 Jan '17

20 Jan '17

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.

SIMCom modems

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 -- ynezz

Information on getting adb on ME906v
by Harald Welte 14 Jan '17

14 Jan '17

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.

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. -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte

Hi Petr, On Mon, Jan 09, 2017 at 08:57:51PM +0100, Petr Štetiar wrote: > according to a lot of sources one would think, that EC20 is based around the > Qualcomm MDM9615, but the picture of naked EC20[1] clearly shows, that there > is Qualcomm MDM9215 chip soldered on the board. Which source is true? :-) Or > it's just a wrong text on that BGA? 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 -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
