The recipe is here
Until now I did not have any problems with this solution.
I formatted the drive (64GB ) as NTFS, because FVAT caused trouble. The NTFS drive also makes it very easy to copy files to and from the device in Windows. If you are Linux user, perhaps it’s better to make an EXT4 partition on it.
It shows up as usual in webconf but that is (and always was) unreliable for file management:
The webconf File Browser works fine, the drive shows up twice, once as /media/root/ZYNTHIAN and once as my-data
On the Zynthian itself I see no difference with the original situation:
I’ve done speed comparisons in the past, and if I remember correctly, there was a slight speed drop on an RPi4 (about 20-30%) and none on an RPi5. That’s of course dependent on the speed of the stick.
It is a fairly safe solution. If you copy the complete zynthian-my-data to the USB drive and rename it to zynthian-my-data-old before you create the symlink, you can revert this simply by deleting the symlink and renaming the old directory back.
Disclaimer: @jofemodo once told me this is not tested nor supported by the devs, so try this at your own risk.
Kind regards,
Hans.
