Question - Minimig SD card

Most SD cards are formatted to only accept upto 511 root directory entries.

This applies to the Minimig too.  Maximum number of files is 511, a handful of which will most likely be used for ROM image, AR3 and FPGA config file.  Folders are not processed on the current PIC firmware.

This is stated in the manual of the last release, page 6.

So the only solution is to keep having to change the files (games) on the SD card when necessary?

I am not a techie person but is there anything possible which can be done in the future to resolve this issue?

It just seems a shame really..

Don't despair! :-)

You can use a software called FATCleaner, written by Jakub to automatically generate the short file names for you and arrange files in alphabetical order.  This saves you a lot of manual renaming.  Link is on the manual too ;-)

500+ ADF images is quite a lot, in my lifetime I never had that many disks on my real Amiga!

But there is a ray of light for those who want a lot of files - the ARM board.  You can then put as many Amiga files and folders as you want in the hard-file.  I *think* you should be able to have an almost 2GB Amiga partition that way.  Jakub might need to confirm this statement, however.  You could then use WHDLoad to cater for all your game needs.

The ARM procesor is powerful enough to support folders and long file names.  It's only a short matter of time until it's released. Should it not support all features in the beginning, they will be put in with new code releases.

Note that the ARM board is on pre-order, so if you want one, visit www.minimig.net [edit: changed .org to .net] for ordering instructions.

Cheers!

So this is hardcoded to Minimig? Too bad, as FAT actually supports upto 32735.

I don't know for sure.  From a peek at the code, it's definite that only the first partition is considered, and that sector size must be 512 bytes.

File is on Google Code here:
fat16.c

My understanding is that limitations stem from the fact that the PIC only has 1.5KB RAM, precluding support for fancy file system features.

What makes sense for Minimig, from a usability standpoint, would be folder support.  Having thousands of files in the root folder would be a nightmare to navigate on the small OSD.

Yes, yes that's it ;-)  

My mistake there.  The pre-order thread is here:
