Hi folks,
I have purchased a DLink DWM-222 with the intention of exploring the
Linux OS running inside it, and if possible, compiling some additional
USB gadgets to use with it.
FWIW, the USB ID's are 2001:ac01 before modeswitch, and 2001:7e3d
after switching.
It creates ttyUSB[0-4] when switched, and the VID:PID added to the
option driver.
I was wondering if there had been any further developments in the
exploration of the A1 hardware or firmware, in terms of gaining a
shell on the device at all without soldering?
Some initial probing has shown some 1.8v signals on some of the test
points, so I will check those with a scope while booting to see if I
can identify some waveforms, hopefully indicating a UART. I do have a
FTDI UART with a voltage reference, so I am fairly confident that I
can access those signals without damaging the device once identified.
Unfortunately, the updated hardware has complete shields over the
interesting bits, so I cannot identify chips, etc. I have also not
been able to find firmware for the A2, the only firmware I could find
was at ftp://ftp.d-link.co.za/DWM/dwm222/Firmware/, marked as A1. I'll
check to see if they are compatible. And of course, will be copying
the driver software from the embedded CDROM.
Regards,
Rogan
Hello,
I am working on a EC25-1 which has problem with the USB communication
with a dwc2 usb host controller [1].
To find the problem my next step was to connect to the EC25 debug UART
on pin 11/12.
But the system needs a root password!
The one you have on your wiki does not work anymore [2].
I think I have the same version "msm LNX.LE.5.0.1-57031-9x40
mdm9607-perf /dev/ttyHSL0"
Do you have another password for this interface or where did you get
this information from?
Thanks for help
