| - | The TG582n comes in at least three distinct hardware variants distinguished by their board name (DANT-1, DANT-T, DANT-V). The only difference seems to be flash chip, which is either 8 MiB or 16 MiB. Other than this, testing so far indicates that the PCB layout is identical for all boards. | + | The TG582n comes in at least three distinct hardware variants distinguished by their board name (DANT-1, DANT-T, DANT-V).

Also, if the active bank fails to boot 3 times in a row (e.g. because of corrupted configs, failed overlay migration), boot from the passive one is attempted for 3 times as well.

| - | The DANT-1 boards come with 16 MiB Flash. This chip is dual bank and able to store 2 firmware images and switch between them when the TG582n runs on stock firmware. This is done to implement a failsafe feature: if an image fails to boot (e.g. corrupted flash or failed upgrade), boot from the recovery one is attempted. | + | The board layout is identical to the others for this same model.
