Jakub has released a new update for all the Minimig owners with the ARM controller:

http://www.minimig.net/viewtopic.php?f=5&t=183


http://minimig.googlecode.com/files/minimig_YQ090911.zip

Changes and new features:

ARM firmware - support for:

- MMC/SD/SDHC cards
- FAT16/FAT32 filesystems
- subfolders (unlimited number of entries and depth)
- Long File Names
- alphabetical sorting of entries
- selection of files and subfolders with a keypress
- scrolling of entries with PgUp/PgDn/Home keys
- selection of parent directory with Backspace key
- up to 4 virtual floppy drives
- up to 2 hard files emulating A600/A1200 hard disk controller (up to 4095 MB each)
- optional higher memory card transfer speed (requires simple hardware modification - highly recommended)
- firmware upgrades directly from the memory card

FPGA - new features:

- improved system timing (blitter, CIAs, ROM)
- minor compatibility improvements (CIA access, INTREQ)
- support for two virtual hard disks
- implemented alliasing of custom register space (Kickstart 1.2 now works)

Upgrade instructions is included readme file.


Enjoy!

Let me guess, SDIO support, needing the 4 data pins to be soldered instead of using SPI mode?

No idea mate, too technical for me...Jakub is the man for this.

@TheDaddy

I'd like to get one of these ARM controllers. Is that hardware an off-the shelf Spartan 3 add-on part that you can buy from Xilinx resellers like Avnet, or something custom by yaqube? Where can I pick one up?

Oh.. and btw, do you have anymore enclosures left?

No ! Ii is a pigiback board with an ARM on it, that replaces the PIC controller, the PIC controller in the Minimig is responsible for loading the FPGA and for Floppy emulation.

Read here:
http://www.minimig.net/viewtopic.php?f=7&t=11

This very useful expansion was made by some hobby developers ( like the rest of the Minimg ) what is missing is someone starting a small production ...

---

It would be nice if someone would make a redesign of the Minimig, Mini ITX formfactor, more RAM a faster CPU and the ARM board would transform the Minimig in something more than just an ADF player.

Or the oposite direction: 68k integration into the FPGA and SD-card handling by integrated 68k CPU.
