pcduino 3 nano heeeeeelp

[Gaetano]

I am trtying to keep my pcduino 3 nano alive. It has been working perfectly under a debian bullseye distro from Johan Gunarsson for 4 years and now I can't get the OTG to work under any release (bullseye, bookworm or trixie) I have explored many avenues, but even a plain manual setup of g_mass_storage doesn't work in a workable way. The drive appears in Windows Explorer after several minutes, and any copy or delete to that gadget drive takes ages (3+ minutes for a 12kb file) before it fails or succeeds silently.

 

I am looking for a forum where pcduino users can help each other.

 

Thank you,

Gaetano.

Userspace has nothing to do with hardware features. I don't know what is the case for A20, but for many others, OTG functionality is driven with overlays. If there are no overlays, you need to edit device tree and change its role. If that doesn't help, it is more complex problem.

More complex, perhaps days / weeks to debug and fix. Most of (Armbian) kernel developers are long gone from this 10+ years old platform  and users can't help.

Also look into previous builds. Finding out when this broke is half of the solution https://fi.mirror.armbian.de/oldarchive/

or by finding a kernel that works https://docs.armbian.com/User-Guide_Armbian-Config/System/#alternative-kernels With any userspace (trixie/noble/jammy ...)

Probably all A10 and A20 boards share this problem.
