Modem Firmware Upgrade - Modem Busy - USB Issues
#1
(edit)***Following the thread below I got the problem solved, turns out sudo su is needed and sudo is not enough permissions to flash the modem***

https://github.com/the-modem-distro/pine...k/releases

It has been suggested that upgrading the firmware on the modem can help Bookworm users get GPS working.
There is no mention in the troubleshooting if I cant even pass the AT commands as it shows the port busy.
I am running a 3/32gb upgrade board PP.
Code:
mobian@mobian:~$ echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
-bash: /dev/ttyUSB2: Device or resource busy

No AT commands means no fastboot possible, no fastboot means no upgrade.

Code:
mobian@mobian:~$ fastboot flash modem NON-HLOS.ubi && fastboot reboot
< waiting for any device >


I am concerned as I understand the GPS device should be on USB1 modem on USB2 but we see.(anyone can post their lsusb to see if there is a difference)

Code:
mobian@mobian:~$ lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I'm nut sure if lsusb lists the (sub-)functions of the USB device.
The modem knows the following tty:
Code:
mmcli -m any --output-keyvalue | grep -F modem.generic.ports.value
modem.generic.ports.value[1]                    : cdc-wdm0 (qmi)
modem.generic.ports.value[2]                    : ttyUSB0 (qcdm)
modem.generic.ports.value[3]                    : ttyUSB1 (gps)
modem.generic.ports.value[4]                    : ttyUSB2 (at)
modem.generic.ports.value[5]                    : wwan0 (net)
The kernel knows the following tty:
Code:
tree /dev/serial/by-id/
/dev/serial/by-id/
├── usb-Quectel__Incorporated_LTE_Module_community_fw-if00-port0 -> ../../ttyUSB0
├── usb-Quectel__Incorporated_LTE_Module_community_fw-if01-port0 -> ../../ttyUSB1
├── usb-Quectel__Incorporated_LTE_Module_community_fw-if02-port0 -> ../../ttyUSB2

got it; I also show same from mmcli -m any --output-keyvalue | grep -F modem.generic.ports.value
I still don't know why AT commands get refused
Code:
mobian@mobian:~$ mmcli -m any --output-keyvalue | grep -F modem.generic.ports.value
modem.generic.ports.value[1]                    : cdc-wdm0 (qmi)
modem.generic.ports.value[2]                    : ttyUSB0 (qcdm)
modem.generic.ports.value[3]                    : ttyUSB1 (gps)
modem.generic.ports.value[4]                    : ttyUSB2 (at)
modem.generic.ports.value[5]                    : ttyUSB3 (at)
modem.generic.ports.value[6]                    : wwan0 (net)
For what it is worth, I also tried sudo echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2 to try to get fastboot mode, same answer: Device or resource busy

If I recall correctly and from https://github.com/the-modem-distro/pine...issues/135 you need to run this from a root shell, so run 'sudo su' to enter root shell and then it should work.

tried that now too, I am not a master of the functional differences between sudoing and running as su but it has almost never been important to my work
Code:
mobian@mobian:~$ sudo su
[sudo] password for mobian:
root@mobian:/home/mobian# sudo echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2
root@mobian:/home/mobian# fastboot flash modem NON-HLOS.ubi && fastboot reboot
< waiting for any device >

I also tried ADB as below from https://github.com/the-modem-distro/pine...LASHING.md
Code:
mobian@mobian:~$ sudo adb reboot bootloader
* daemon not running; starting now at tcp:5037
* daemon started successfully
error: no devices/emulators found
same result as above when run as root

I just tried it and it worked for me (tried with sudo echo in root and that doesn't work, already sudo as root@mobian).




Code:
mobian@mobian:~/Downloads$ sudo su
[sudo] password for mobian:

Voodoo electronics, I cut/pasted from your post and it worked, is it different than mine??  Anyways it flashed, lets go GPS?
(edit)
Getting useful results from the GPS now, (sudo watch -n 5 mmcli -m any --location-get) still waiting for it to update almanac as I dont like to use wireless nodes to speed up a fix, not locked yet, but receiving satellite signals.

still relevant there are four firmware versions, how to choose which, the git page
https://github.com/the-modem-distro/pine...k/releases
is pretty vague about choosing the one "which works best for you"

(edit2)
Can anyone explain why I can run gnome maps for 30 min and never get a GPS lock but maybe 30sec of running the puremaps and it finally gets a location in sudo journalctl -u geoclue.service -n 20 as well as all apps.
I reject the stupid voodoo aspect we are not Adeptus Mechanicus, but I do not see a good causal connection.

Excellent news, glad it worked!

You had
'sudo echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2'
as root and that doesn't work (not a sudo / su expert) whereas
'echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2' does...

Hope GPS works better.

More news...
I don't know if this is modem firmware or the OS upgrades; I cant do data or phonecalls now, they drop without ringing out.
I did try all four firmware versions though, but any option I choose in the mobile network crashes the settings GUI.
(edit)
I just received a call, now calling works in and out; but still cant go data. WHere is the .conf file for the dialer and other mobile network settings?

I am not sure this was such an issue with the factory firmware but now I am having an issue where after 12-24 hours I show 4g and full bars but cant receive calls or SMSs, a quick phone reboot(vs going into terminal and rebooting just the modem) as I needed to make a call and I get a huge backlog of SMSs and modem is OK.
I have done this a few times now and it seems to be an issue.

Maybe I should make a startup script daemon to reboot the modem every few hours.
Anyone have a better idea?

(edit) for a baseline I re-flashed to ADSP Version 01.002.01.002
