EM7455 brick?.


#1

Hi to all, I have one EM7455.

When execute list stored images only get modem image, not have a pri image.

root@elmemis-VirtualBox:/tmp/cosas# qmicli -d /dev/cdc-wdm0 --dms-list-stored-images
[/dev/cdc-wdm0] Device list of stored images retrieved:

	[0] Type:    'modem'
	    Maximum: '4'

		[modem0]
		Unique ID:     '?_?'
		Build ID:      '02.08.02.00_?'
		Storage index: '1'
		Failure count: '0'

How to fix it? is possible?.

For example, the tool qmi-firmware-update I give an error on execution:

root@elmemis-VirtualBox:/tmp/cosas# qmi-firmware-update     --update     -d 413c:81b6     --device-open-mbim     SWI9X30C_02.20.03.00.cwe     SWI9X30C_02.20.03.00_Generic_002.017_000.nvu -L qmi.log
loading device information before the update...
setting firmware preference:
  firmware version: '02.20.03.00'
  config version:   '002.017_000'
  carrier:          'GENERIC'
rebooting in download mode...
error: error waiting for TTY: waiting for device at '/sys/devices/pci0000:00/0000:00:0b.0/usb1/1-1' timed out

Help me please :neutral_face:

I believe you should using windows for firmware update instead because so much “internal factors” which might causes “software bricks”. I had same problems where end up with device totally not detected. If still want to use unix flavours then please use tools that provided by sierra itself.

The updater depends on serial driver support. Do you have the qcserial driver installed, and is it patched to match the configured boot device ID? Assuming that this matches your Dell application device ID, you can find out with something like

modinfo qcserial|grep 81b5

This device ID is a very recent addition (only in v4.11-rc4+, v4.4.58+, v4.9.19+), so it’s likely missing unless you have built the driver/kernel yourself.

Look at that the kernel log (dmesg) when you run the updater and see what happens. You should see the modem disconnect and the reconnect with a single serial interface and the boot device ID. But if the qcserail support is missing, then there won’t be any driver binding and the update will fail.

The modem is hardly bricked as long as you can talk QMI over MBIM to it… Looks like it is fully functional to me. But it will probably be in low power mode until you have either updated the firmware or set the firmware preference back to whatever it was before you started.

Maybe, maybe not. One valid reason not to do that is if the modem considers it unnecessary (because it already has the required firmware files).

You write a verbose “qmi.log” file, as recommended. But what does it tell you? It should show the QMI requests and the replies from the modem. It should also show any detected udev activity.


#6

Hi,
Modem is missing files. It only has the img of the modem, but the img of the pri.
I do not see udev activity.
Attach qmi.log.

qmi.log (40.5 KB)


#7

This is weird. I see that the modem requests the missing pri image and the responds successfully to the set-operating-mode ‘reset’ request. Then there is nothing more. The modem should reset here. I cannot explain why it doesn’t.

You might try other ways to switch it into ‘boot-and-hold’ mode, like AT command. But you’ll have to enable serial functions first then.


#8

@dl5162 thanks for all.

How to activate AT interfaces?
I use EM7445 module with m2 to USB2 adapter.


#9

hi,

You can use “minicom” tools (shall be installed on ubuntu) or other same tools. I believe below tools is useful enough for firmware update (mork.no/~bjorn/MC7455-fix.txt)


#10

The commands action is RESET, don’t work.

AT!RESET
qmi-firmware-update --reset

Is it possible to debug this problem?


#11

hi,

I believe AT Commands “AT!RESET” should works, but for “qmi-firmware_update”, please do check a proper commands via “qmi-firmware-update -H” where it shows all related commands. Please do check from that “website” link where it shows another “perl” commands how to reset as well as “boot and hold” (qdl).


#12
AT!RESET

Return OK but not reset the device. AT!BOOTHOLD is the same. Tomorrow record a video.


#13

Hello,

Have you try tools from this website ((mork.no/~bjorn/MC7455-fix.txt)). I’ve done for device checking and working fine and believe should work for rest and “qdl” mode. for that “AT” commands, have you done "AT!ENTERCND=“A710” prior AT!RESET or AT!BOOTHOLD ? in order any actions to be activated.


#14

Those methods are unsupported and very risky, and depends on being able to boot into “boot-and-hold” (QDL) mode anyway. Which is the problem here… If that had worked, then the normal qmi-firmware-update would work too.


#15

Don’t work :frowning:


#16

Hi,

So weird for me. Anyway, I’ve tested on my MC7455 installed on Ubuntu 17.04. I’m using “picocom” to access that module as below:

if not been installed, please install it “sudo apt-get install picocom

sudo picocom /dev/ttyUSB2

Terminal ready
ati5 # this command shows detail about product.
ok
atz # echo on
ok
at!entercnd=“A710”
ok
at!usbcomp?
Config Index: 1
Config Type: 1 (Generic)
Interface bitmask: 0000050D (diag,nmea,modem,rmnet0,rmnet1)
ok

Please do test from your end and no harm for that module.

To exit from “picocom”, press Ctrl-A followed by Ctrl-X


#17

Hi,

So weird for me. Please do test using “picocom” (if not exists, please install)

sudo picocom /dev/ttyUSB2

Terminal Ready
ati5 # shows product details
ok
atz # echo on
ok
at!entercnd=“A710”
ok
at!usbcomp?
Config Index: 1
Config Type: 1 (Generic)
Interface bitmask: 0000050D (diag,nmea,modem,rmnet0,rmnet1)
OK
at!usbpid?
!USBPID:
APP : 9071
BOOT: 9070
OK

you can try and no harm for that module, to exit press Ctrl-A followed by Ctrl-X. If you got that result, I believe AT!RESET or AT!BOOTHOLD should work.


#18

Hi,

So weird for me. Based on previous info that module is “DELL Branded” and looks like all “AT” was disabled.

You can try checking which current “Current USB composition” configured for that module and no harm to use below tool.

$ sudo /usr/local/bin/swi_setusbcomp.pl --device=/dev/cdc-wdm1 # default device=/dev/cdc-wdm0
Running in QMI mode (driver=qmi_wwan)
QMI msg ‘0x0021’ returned status = 1
QMI support verified
supports 33 QMI subsystems:

  • 6 - DM NMEA AT QMI SUPPORTED

Current USB composition: 6 # this is mine and please do check yours.

If set to “9” which means only MBIM and all “AT” are disabled.


#19

AT!RESET or AT!BOOTHOLD do not do anything :frowning:


#20

Hi,

That means your EM7455 module is configured for MBIM only and all “AT” commands are disabled. You can try “swi_setusbcomp.pl” from that website link (no harm for that module) just to verify which “Current USB composition” currently configured for that EM7455 module and believe configured as “9” and for my module is configured with “6” as below:

$ sudo /usr/local/bin/swi_setusbcomp.pl --device=/dev/cdc-wdm1

Current USB composition: 6

  • 6 - DM NMEA AT QMI SUPPORTED
    7 - DM NMEA AT RMNET1 RMNET2 RMNET3 NOT SUPPORTED
    8 - DM NMEA AT MBIM SUPPORTED
    9 - MBIM SUPPORTED
