I have the "official" GPH "breakout box" (bare circuit board version). I've got it linked up to my Mk1 GP2X and I have TV-OUT and the external serial console working fine.
The next thing that I wanted to try was getting a hard disk attached via the BOBs host USB ports. My GP2X has version 2.0.0 firmware, which I think means that I should have all the correct kernel modules an so forth installed without adding any third-party stuff? In my Settings -> System menu I have:
I'm attempting to use a LaCie branded USB 2 external drive enclosure, which contains a 160Gbyte Samsung SpinPoint disk. This has a single FAT32 LBA partition set up as primary partition number 1 (I've tried both a FAT32 partition spanning the entire disk, and a smaller one limited to 32Gbytes size). I don't think that I have power issues with the drive - it has its own external mains adaptor rather than drawing current from the USB connection. The drive is the only USB device plugged in to the BOB. When I power up the GP2X, the external disk is detected as mass-storage but there is an error message to say that the partition table can't be read due to an I/O error:
Devfs creates a /dev/sda symlink, but no /dev/sda1. Naturally none of the external storage stuff in the GP2X menus work.
From the serial console shell, I do appear to be able to read sector 0 of the disk without I/O errors (dd will read from /dev/sda without errors, the fdisk command shows what I expect from the partition table). I've tried re-writing the partition table using fdisk on the GP2X and then restarting. The changes I make to the partition table "stick", so they are getting written to sector 0 successfully, but the kernel still claims not to be able to read sector 0 when it next boots.
If I connect my USB SD card reader to the BOB instead of the LaCie drive then the partition table on that is detected and I am able to use Explorer/PhotoViewer/mplayer/etc with the files on the card via the "EXT Storage" option of the file browser. This latter success leads me to suspect that the BOB hardware is working okay and that there might well be some compatibility problem with the particular LaCie external storage enclosure that I'm using.
Do these symptoms ring any bells with anyone?
Has anyone got any success stories regarding using external hard disks with the BOB and firmware 2.0? I'd be particularly interested in hearing about any workarounds that people have had to come up with, and brands / model numbers from any working setups ...
