Hardware Projects » E1/T1 Hardware Interface (including icE1usb)

Hi folks,

I've been struggling all afternoon to get the DAHDI drivers working with the icE1usb on Debian 11 or Ubuntu 20.04.

I've installed the Osmocom DAHDI-Linux and mainline DAHDI-tools with the below steps:

apt-get install linux-headers-`uname -r` git dfu-util make gcc autoconf libtool
git clone https://git.osmocom.org/dahdi-linux/
git clone https://github.com/asterisk/dahdi-tools

cd dahdi-linux
sudo make install

cd ../dahdi-tools
sudo autoreconf -i
./configure
sudo make install
sudo make install-config
dahdi_genconf modules (no output)
cat /etc/dahdi/modules (returns boilerplate config, comments only, no config.)
dahdi_genconf system (Returns "Empty configuration -- no spans")

Not 100% sure on if I should be running modprobe for the icE1usb but here's the output if I do:

modprobe icE1usb
modprobe: ERROR: could not insert 'icE1usb': Invalid argument

I get blinking green LEDs on both the E1 ports and solid red on the RGB LED.

But lsdahdi and dahdi_scan both return nothing, suggesting they're not able to detect it.

Osmoe1d is not running - but if I do run it, it does appear to see the icE1usb.

I thought maybe it was a firmware issue, so flashed what I think it the latest firmware, for the firmware I'm using is from the latest folder on the FTP icE1usb-fw.bin whith the creation timestamp 2022-Jan-29 03:01:07, and the Gateway Firmware from tnt - icE1usb-fw-0.2-6-gfdfabf9.bin with the creation timestamp 2020-Oct-09 11:46:48.

Both flashed OK.

lsusb sees it OK, after flashing, device ID suggests it's no longer in DFU mode.

Bus 001 Device 009: ID 1d50:6145 OpenMoko, Inc. icE1usb

I'm able to see the device in lsusb and syslog when I plug it in:

I can see DAHDI it installed in modprobe under /etc/modprobe.d/dahdi.conf,

ps aux does not show a DADHI service, although I'm not 100% clear on if it is supposed to?

Any hints would be much appreciated!

Thanks!
