Gobinet gobiserial in openwrt issue with em7565

I have cross compiled gobinet and gobiserial for openwrt and my netgear r7800. I have tested it with a mc7455 and it seems to be working great. I then plug my em7565 into the router and I just get a kernel crash and reboot after it trys to establish a connection. It never makes a connection. Are there different gobi drivers for the mc7455 and em7565 or are they the same? I’m using QMIdriversS2.35N2.54 Model: EM7565 Revision: SWI9X50C_01.07.02.00 6c91bc jenkins 2018/06/13 23:08:16 Mon Dec…

Hi @jyijyi ,

I just want to try it do you have any idea ?

[jyijyi]

[larry1]

Hi @jyijyi ,

Thanks, Does it can porting to kernel 5.10.XX ?

[jyijyi]

why don’t you use MBPL?

this user uses MBPL with openwrt kernel 5.10

MC7421 QmiDevice: Transaction timed out

HI We have a unit of 100 MC7421 devices and we suffer from their bad behavior, most of the time when the board restarts or turns on/off the module will disappear or the qmi command fails to complete the transaction and we have to restart the board a lot of time to make it work we tried the MBPL_DRIVERS_R32 driver and the generic driver and both gave the same result so our question did you have any idea how to resolve this the issue below the module didn’t show up after rebootand root@tes…

@larry1

Does it can porting to kernel 5.10.XX ?

Hi @jyijyi ,

What should I disable kernel module in kernel when I use MBPL?

[jyijyi]

why did you need to disbale kernel module?

BTW, you can read the user guide of MBPL here:

https://source.sierrawireless.com/resources/airprime/software/mbpl/mbpl-software-latest

[larry1]

Hi @jyijyi ,

Because I saw kernel has some like “sierra” , so I don’t know I should disable it or not?

[jyijyi]

seems that flag is for gobiserial, not for MBPL:

Getting started with MC7430 on Android

Example to have the serial driver: under /kernel/hikey-linaro/drivers/usb/serial/Makefile, add obj-$(CONFIG_USB_SERIAL_SIERRAWIRELESS) += sierra.o under /kernel/hikey-linaro/drivers/usb/serial/Kconfig, add obj-$(CONFIG_USB_SERIAL_SIERRAWIRELESS) += sierra.o config USB_SERIAL_SIERRAWIRELESS tristate “USB Sierra Wireless Driver” help Say M here if you want to use Sierra Wireless devices. Many devices have a feature known as TRU-Install. For those devices to work properly, the U…

anyway, you need to make some test in both case to see what happens

Hi @jyijyi ,

What is different between usb_wwan, sierra_net, usbnet and qmi_wwan ?

[jyijyi]

you can read the comment here:

torvalds/linux/blob/master/drivers/usb/serial/usb_wwan.c

torvalds/linux/blob/master/drivers/net/usb/qmi_wwan.c

usbnet is from Gobi driver which is not recommended to be used anymore
sierra_net is for some old product…

[larry1]

Hi @jyijyi ,

Does it have conflict issues ?

[jyijyi]

Yes
Mbpl driver cannot use together with gobi driver

[larry1]

Hi @jyijyi ,

If I use MBPL what depends like ?

DEPENDS:=+kmod-usb-core kmod-usb-serial

[jyijyi]

i never used operwrt, you need to make some test

[larry1]

Hi @jyijyi ,

Should I use option.c when I use MBPL ?

[jyijyi]

no, i don’t think so
