mtk_t7xx driver commands question

[brcisna]

Debian 13

Code: Select all

uname -a
Linux server3 6.11.10-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.11.10-1 (2024-11-23) x86_64 GNU/Linux

Have a Fibocom FM350-GL cellular modem working with for the first time.
With the native mtk_t7xx driver we get the following driver

Code: Select all

lsmod |grep t7xx
mtk_t7xx              147456  0
wwan                   28672  5 mtk_t7xx
  

the modem works great through ModemManager & NetworkManager and udev generates the following character devices

Code: Select all

  ls -l /dev/wwan*
crw------- 1 root root 245, 0 Dec 13 22:11 /dev/wwan0at0
crw------- 1 root root 245, 1 Dec 13 22:11 /dev/wwan0mbim0 

Can run AT commands through the /dev/wwan0at0 interface

After finding this documentation on this driver, which is pretty recent by the way. Am wanting to expose the adb & mipc ports to try and update firmware through these interfaces. All the software for these are very much Windows centric.
https://docs.kernel.org/networking/devi ... /t7xx.html
When i run the cat command suggested here in the linked documentation the devices are never found which when browsing they do not exist on this system.
When i do a 'locate t7xx' i never find anything such as t7xx shown ,other than the actual kernel module . Am probably misunderstanding what is shown in the documentation

Code: Select all

 0c:00.0 Wireless controller [0d40]: MEDIATEK Corp. T700 5G Modem [5G Solution 5000] (rev 01)
	Subsystem: Hewlett-Packard Company Device 8914
	Flags: bus master, fast devsel, latency 0, IRQ 16, NUMA node 0, IOMMU group 57
	Memory at 33ff1000000 (64-bit, prefetchable) [size=32K]
	Memory at f3000000 (64-bit, non-prefetchable) [size=8M]
	Memory at 33ff0800000 (64-bit, prefetchable) [size=8M]
	Capabilities: <access denied>
	Kernel driver in use: mtk_t7xx
	Kernel modules: mtk_t7xx
  

How do i figure out how to locate this device in sys to run the commands mentioned in the t7xx documentation,,,,,,,,in simple terms,,for a simple minded person

TIA

You can probably use the find command:

• find - search for files in a directory hierarchy

Hope this helps.

Hello @brcisna,

Have you sorted it out ?
