Any UsbNet solution for Eclipse2E

[lordeagle]

Hey guys,

I got an Eclipsa2E in hope to use it as VNC screen for outdoor works.

To avoid updates and keep a stable connection I used the built-in usbnet firmware on my H2O and niluje's usbnet-toggle. I thought I can use just the same on Eclipsa, but now it seems as there are no drivers shipped with the Eclipsa2E models.

Is there any chance to get usbnet running anyway, every pointer is welcome.

Currently the toggle does not work with the latest official utils.

[root@kobo bin]# usbnet-toggle
* Switching from USBMS to USBNet . . .
insmod: can't insert '/drivers/mt8113t-ntx/usb/gadget/arcotg_udc.ko': No such file or directory
! Could not load arcotg_udc.ko (it might be built-in on your device)
insmod: can't insert '/drivers/mt8113t-ntx/usb/gadget/g_ether.ko': No such file or directory

Looking into the /drivers directory, there is indeed not much to see that looks like an usbnet driver.

[root@kobo bin]# tree -la /drivers/
/drivers/
`-- mt8113t-ntx
    `-- mt66xx
        |-- wlan_drv_gen4m.ko
        |-- wmt_cdev_bt.ko
        |-- wmt_chrdev_wifi.ko
        `-- wmt_drv.ko

Eclipsa or Elipsa?

FWIW, on my Clara HD, the drivers are in /drivers/mx6sll-ntx/usb/gadget/:

# ls /drivers/mx6sll-ntx/usb/gadget/
configfs.ko g_zero.ko usb_f_ecm.ko usb_f_obex.ko
g_ether.ko gadgetfs.ko usb_f_ecm_subset.ko usb_f_rndis.ko
g_file_storage.ko libcomposite.ko usb_f_eem.ko usb_f_serial.ko
g_mass_storage.ko u_ether.ko usb_f_fs.ko usb_f_ss_lb.ko
g_ncm.ko u_serial.ko usb_f_mass_storage.ko
g_serial.ko usb_f_acm.ko usb_f_ncm.ko


On my Clara HD, These modules were listed during a USBnet connection:

# lsmod
g_ether 5247 0 - Live 0x7f03e000
usb_f_rndis 16195 2 g_ether, Live 0x7f035000

Here's a Gateworks article on OTG modules:

Note that the Kobo Libra Color, a MediaTek device like your Elipsa, is using Secure Boot, which requires a signed kernel.

Maybe try something like "dmesg | grep hash" to see if you get similar messages as for the Libra Color?

Here's a LWN article on Verified U-Boot:

On my Clara HD I can see if a module is configured:

# cat /proc/config.gz | gunzip | grep ETH
CONFIG_USB_U_ETHER=m
CONFIG_USB_ETH=m
CONFIG_USB_ETH_RNDIS=y


But can someone compile unsigned kernel modules and add them to a signed kernel?
Apparently not:

On the plus side, I know that at least my android devices can provide a WiFi hotspot without being connected to the internet, so your Kobo can have WiFi on and connect to a VNC server without being exposed to unwanted updates.
