how to increase # of VFS handles?

Postby tschak909 » Sat Feb 11, 2023 8:15 pm

We have a unique situation where we need more than 8 VFS handles.

We can see that we can change the value inside the VFS code inside ESP-IDF, and it works, but is there a way to pass a configuration option, instead of having to fork and make this change in-code?

I don't think the amount of VFS handles itself is bound. Do you mean the max VFS filesystems you can register (#define VFS_MAX_COUNT 8)? There's no easy way to change that indeed. You could copy the vfs component to your own project (components in a project will override components in esp-idf of the same name) as a short term fix, and for the longer term, I think this could be implemented as a Menuconfig option in esp-idf. Can you file an issue for this, or if you're willing, create a patch and a pull request for that? That way we can keep track of it.
