Hello,
I would like to update the firmware of an RC7620 modem under embedded Linux with the command “qmi-update-firmware” and libqmi.
Thank you for your help
See you soon

Have you tried the MBPL FW downloader?
https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest/
Thank you for your reply.
my embedded linux is a linux from scratch.
the “qmi_wwan” and “usb_wwan” are not a module. They are in the kernel. Is it a problem ?
In my application software, i use “qmi-network” to order the modem.
which is why I was thinking of using “qmi-update-firmware”.
So, to use “fwdwl-litearm”, what is the modelfamily for RC7620-1 ?
could you give me the link to download the latest firmware for the RC7620-1 ?
Thank you for your help
See you soon

Thank you jyijyi for you reply.
Here is the command for the firmware update:
./fwdwl-litearm -m 4 -P 1-1.1 -f /RC76xx_Release8_SIERRA_R2C_7620.spk -i 1

I took this file from the link you gave me.
can you tell me where to find the right file ?
Thank you for your help
See you soon
From the lite-fw-download-readme.txt
3. Supported Devices
====================
- Based on SDX55, Ex: EM9190/EM9191/EM7690, etc.
- Based on 9X50, Ex: EM7565/EM7511/EM74X1, etc.
- Based on 9X30, Ex: EM7455/EM7430, etc.
- Based on 9X15, Ex: EM7355/EM7305, etc.
- Based on 9X07, Ex: WP76xx
Modem formfactor (EM/MC/WP/HL) is largely irrelevant for the purpose of this app and FW download feature. The overall functionality from a host perspective is equivalent.
Not quite sure if it works on RC module right now.
You might try to install attached USB driver by
make
make install
Suggest you testing on Ubuntu 18 PC first.
MBPL_Drivers_USB_R20_ENG1-src.tar.gz (23.0 KB)
it is not possible to do the test under Ubuntu 18 PC.
The modem is soldered into the target.
you say: “Not quite sure if it works on RC module right now.”
what is the best method of updating the firmware for the RC7620 modems ?
I have 150 products to do
Thank you for your help
you can modify the makefile to use toolchain to compile the driver and install in your system to try.
I compiled and installed the 3 drivers in my target.
but the problem remains the same, the .spk file does not seem to be supported.
How do I update the modems ?
Thank you for your help

Then it is not supported with the MBPL SDK.
I saw in the link
https://source.sierrawireless.com/resources/airprime/software/rc76xx/rc76xx-firmware-release-8/#sthash.w1a0rqqD.i0ayPHaw.dpbs
It asked you to use the " Linux QMI SDK Application Developer Guide".
In this case, you need to use the GobiSerial driver and GobiNet driver together with the Linux QMI SDK.
BTW, have you tried to update the FW by AVMS website?
it is written in your Linux QMI SDK documentation :
** NOTE: This product is now EOL. Sierra Wireless recommends customers move to MBPL on supported modules.
the RC7620 modem is a very recent product. I don’t understand. 
don’t you have another solution for me ?
we have been delivered 150 RC7620 modems with non-working Beta firmware. 
For the update with AVMS website, it is too complicated to have to fill in 150 IMEI - Serial number - connected to the network…
As you tested that MBPL seems cannot work with RC module…
So using the old SDK should be the only way. (other than AVMS)
The old SDK is not the solution as I need to blacklist the qmi_wwam driver used by the modem in operation.
I don’t think it’s up to me to say whether MBPL doesn’t work with the RC7620.
It would be up to you to confirm this.
it seems to work except that the .spk file is the wrong format ! why ?

I believe you can use gobinet
Do you have a document that simply describes the procedure to follow ?
Can you try the MBPL R20 again?
- in AT command port, enter AT!BOOTHOLD, after that only /dev/ttyUSB is seen
- run the following (-f should be specify the folder):
owner@ubuntu:~/QMI/MBPL_SDK_R20_ENG4-lite.src/SampleApps/lite-fw-download$ sudo ./bin/fwdwl-litehostx86_64 -m 4 -d /dev/ttyUSB0 -p /dev/cdc-wdm0 -t 1 -f /home/owner/Desktop/RC7620_FW/

We move on. Thank you for your help.
After “AT!BOOTHOLD” command, /dev/cdc-wdm0 and /dev/ttyUSBx (x=1,2,3) disappears and do not reappear.
Here is the result of the test: how to ensure that the QMI device path is correct ?
AT!BOOTHOLD
OK

Can you check dmesg?
After at!boothold, you should see qcserial driver enumerate one usb port such as /dev/ttyUSB0
here is the information added in dmesg after the AT!BOOTHOLD command
ttyUSB0 is not visible in the folder /dev. why ?
