Upgrade SD card in A600GS

[broadblues]

It does this automatically on first boot with new card.

With a new image. A working image backed up to a new card won't resize. It's planned to maybe add this but, the mechanism needs fine tuning.

If you are confident with linux the approach described by ernsteiswuerfel will work in the mean time.

Its all the same image. It should auto resize by itself. However sometimes, its needs to be triggered manually.
I upgraded mine to a larger faster card and it automatically resized. However others have said, theirs did not.

This is because it only resizes on first boot.

That latest A600GS menu update will check the partition size verses media size and offer the option to resize on next boot if more than 10% free space is found.
