To be more specific, I had assumed that if one changed the file by hand the amplifier could detect that its contents didn't match the CRC and would therefore refuse to load it. thumb5, you were right! my bad the CRC check failed the file, the D unit refused to load and the display showed a message saying a corrupt config file!

At the time this was all introduced, it was somebody on Computer Audiophile who complained to Devialet after they initially put these items into the Configurator. Very shortly afterwards they allowed these to be excluded and updated the firmware. I've not kept up with this so its possible that the approach is now different, but AFAIK it should still be possible to setup a config file with no Wifi details, and then edit them by hand later without invalidating the CRC..... ?

This txt file should be on the card together with the "dp_cfg.txt" config file. There is no editing of the "dp_cfg" config file involved. This would invalidate the config as mentioned by IanG. RE: Stand-alone/self-hosted configuration - thumb5 - 04-Jan-2015 That's very handy to know, thanks. |
