Would you be open to run the firmware updater tool with my modified rootfs, that would enable ADB for the stick?</div><div class="">I think the A1 firmware is compatible, but I cannot say for sure. All I know is that my stick's LED doesn't properly do status indication since I run the upgrade, but otherwise it functions as a modem.</div><div class="">I'd be happy to co-operate on this project, because I think it is quite interesting.</div><div class=""><br class=""></div><div class="">About the shields: as it could be seen on the pictures I just lifted the metal with a screewdriver to reveal the chips. The A2 has those maybe soldered on?</div><div class=""><br class=""></div><div class="">Also I just noticed D-Link has released 2 new firmwares since I last checked.

I do have a<br class="">FTDI UART with a voltage reference, so I am fairly confident that I<br class="">can access those signals without damaging the device once identified.<br class=""><br class="">Unfortunately, the updated hardware has complete shields over the<br class="">interesting bits, so I cannot identify chips, etc. I have also not<br class="">been able to find firmware for the A2, the only firmware I could find<br class="">was at <a href="ftp://ftp.d-link.co.za/DWM/dwm222/Firmware/" class="">ftp://ftp.d-link.co.za/DWM/dwm222/Firmware/</a>, marked as A1. I'll<br class="">check to see if they are compatible. And of course, will be copying<br class="">the driver software from the embedded CDROM.<br class=""><br class="">Regards,<br class=""><br class="">Rogan<br class="">_______________________________________________<br class="">qc-linux-modems mailing list<br class=""><a href="mailto:qc-linux-modems@lists.osmocom.org" class="">qc-linux-modems@lists.osmocom.org</a><br class="">https://lists.osmocom.org/mailman/listinfo/qc-linux-modems<br class=""></div></div></blockquote></div><br class=""></div></body></html>
