DSGW-210 Device bricked, Debian packing image unavailable

Technical Support DSGW-210

I had some issues on my device and tried a clean “factory-reset” and flash-erase with reinstallation.

Unfortunately a custom compiling of the firmware failed from the start (maybe because I got Ubuntu 20.04 and not the recommended 18.04), and the documentations’ link for the prepackaged Debian image is broken “Debian Image Firmware Packaging” (https://drive.google.com/file/d/1syrxEJWBEs3wl8ocxHyiqF9Yo9u-AaRi/view?usp=sharing)

So I stuck with the prebuilt Ubuntu image and flashed that on the device with the “AndroidTool.exe”, but now the device is bricked, not even the LED will start up any more - somehow the tool seems to detect the gateway as “MASKROM Device”, but nothing else works any more.

  1. Is there a working link for the Debian11 prebuilt image to flash?
  2. What steps can I do to flash a new bootloader and device on my device?

I did manage to get it running again with a new provided Debian DUSUN image (DSGW-210-Debian_image_RV1.3.5) - despite no LEDs working and the “AndroidTool” output being somewhat ambiguous, “just flashing” into the blind seemed to have worked.

But, now I have an old problem again with the BLE state - I had a solution for the older compiled image/kernel, but the script does not seem to work properly for the newer version that I got now:

After running this:

./bflash -d /dev/ttyUSB0 -b 500000 -f /tmp/bt_rcp-BG21_768_OK_32_conn.gbl

hciattach /dev/ttyUSB0 any 115200 noflow

at least hciconfig -a finally shows an adapter, but the mac-address is still 00:00:00:00... and hciconfig hci0 up runs into a timeout.

Do you have updated docs and scripts for the new Debian version, or a working link for the older image (I think 1.2.4?)
