Flash a module from the card

in this fork since v2.26.0

A 2 GB image is usually already on the board's own SD card. Installing it meant typing its path from memory into a field, and finding out minutes later whether you had.

The argument

The interface never decides what is flashable. It asks the board, and the board answers per entry with a reason -- too small, wrong magic, a directory -- so the list and the refusals come from the same place that would do the writing.

A module in node 1 or 2 will not flash while a USB card sits in that node's mini-PCIe slot; see the FAQ.
