Update DL2 firmware from 1.4.4 to 1.4.7

DL2 Update

The trouble is the instructions on the Resol website for this update are wrong. I found helpful instructions on the way back machine, but even those had to be adjusted.

Here's what worked for me:

  1. Make sure you are on firmware version 1.4.5 or lower. Go to http://192.168.1.100/cgi-bin/get_resol_device_information (replace 192.168.1.100 with your DL2’s IP address)
  2. Format your SD card. Formatting on the Mac with MS-DOS(FAT) didn’t work for me. I ended up formatting it on my Panasonic camera.
  3. Insert the freshly-formatted card into the DL2, wait till the flashing green light turns solid. . .
  4. Take the card out and put it in your computer: you will see a folder DL2 with the log files in it. If you don’t, the DL2 hasn’t recognized the SD card.
  5. Unzip the firmware.zip file you downloaded from Resol. At the top level, you will see firmware.bin and firmware.yml. Copy them to the top level of the SD card and rename them resol-dl2-firmware.bin and resol-dl2-firmware.yml.
  6. Eject the card and insert it into the DLun2. The green light will blink green and turn solid. After a few minutes, go to http://192.168.1.100/cgi-bin/get_resol_device_information again you should see version 1.4.7.

Hopefully Resol's instructions for updating from 1.4.7 o 2.x are correct. I haven't tried it.

Thoughts on updating to 2.x

It looks like you won't be able to upgrade directly from 1.4.7 to 2.2.1. 1.4.7 still uses Ruby and needs a firmware.yml file, and that is missing in the 2.2.1 distribution. So you'll need to upgrade to 2.1.5 first. Taking a cue from Daniel Wippermann's server, you can get the 2.1.5 zip file by running the command:

wget http://cdn1.resol.de/firmware/RESOL_DL2-2.1.5-201602081156-Firmware.zip

After unzipping that, you should be able to follow RESOL's instructions to copy the RESOL directory (with the DL2/firmware.* files) to the SD card.

In fact, I suspect that the intermediate upgrade from 1.4.4 to 1.4.7 could be eliminated if you copied the RESOL/DL2/firmware.* files from the 2.1.5 distribution to the root of the SDCARD and renamed them with the resol-dl2- prefix as described above.
