    Good call on the repository part. That definitely makes more sense than a distro.

    Okay, flashing the OS onto the Sheeva, I have to make a decision and I'd like some advice.

    Should I flash Debian to the internal memory on the Sheeva or to an external SD card?

    According to the instructions that PaulF linked me to, you can install Debian to any device (internal memory, USB stick, SD card). However, the USB stick is sometimes not recognized, according to the instructions, and the SD card requires an experimental bootloader.

    I've extracted the Debian tarball and it is small enough to fit onto the internal memory without slimming it down. But according to the plug computing instructions, I'll have to to add an MTD Utils file to the distro as I prepare a jffs2 image. However, I can't connect to the location he points to as having that file. And I'm a little confused about which computer the file folder system is supposed to be on in step 4.

    Thanks for any help you can give me. I'll write this all up in a clean thread and in the wiki when I'm done.

    uboot should be able to boot to an external usb/sd card shouldn't it? Is the problem that it isn't always being recognized? What's the experimental bootloader? Just a newer version of uboot or something?

    If you can, I'd put debian on an external usb/sd. That way you can slip it out, mount it with your desktop and manipulate things there.

    Good news, I now have a ARM VM that I can start compiling on. I've been working the past few nights to properly debianize the openice packages. I hope to have some sort of repo up next week. We'll see...

    Really, I would suggest flashing to the internal memory on the device. If you're not invested in what's in there right now, why mess about with the heartache of using other media? It's not like you can't reflash it back to the default one if you don't like the new one.

    I wouldn't recomment futzing with the bootloader, especially one marked experimental. Specifically, for as long as you don't touch the bootloader, you can screw up flashing new distros and it isn't a problem [turn off. turn on. try again.]. If the bootloader goes south, fixing it [probably] requires a soldering iron.

    prepare a jffs2 image
    I would still strongly urge you to try ubifs instead. The difference is only in how you build the image, and the kernel. You don't even need to rebuild the kernel yourself, as ones built to meet your needs are available linked from that page.

    I have it working fine on a usb stick. The only issue is if any other USB devices are plugged into the hub, it won't boot successfully. That's not a problem for me though because mine stays on all the time and linux doesn't crash =)

    Okay, success! After a couple of false starts and a LOT of trying to get the serial port to work on OS X, I've:

    1. Downloaded the Debian ARM kernel and extracted it to an SD card.
    2. Configured the Sheeva to boot from the SD card.
    3. Accidentally mistyped the setenv commands and whacked the plug but easily corrected it.
    4. Have a working full Debian install on an SD card.

    I left the Nand untouched because it seemed simpler to get the SD card version working first. If I made a mistake, just remove the SD card and reboot from Nand. Sorry, PaulF but upgrading to ubifs was one more unnecessary complication that decided to bypass.

    Tomorrow, I will test to see if the FTDI functions using my NMEA compliant GPS. Maybe will try to install chunkyks' obdgps logger. If that works, then Fusion brain.

    Forgot to check - does Debian come with a LAMPS install on it?

    [Edit: I have gotten the serial port to work on OS X's terminal window now using the command 'screen cu.[usbdevice letter B] 115200' where usbdevice letter is the device found in /dev/cu.* Mine happens to be cu.usbserial-FTS2Z6B6B so the command is 'screen cu.cu.usbserial-FTS2Z6B6B 115200'. The usual response when I did this was a blank and unresponsive screen. After getting the blank screen, it is necessary to reset the Sheeva plug using the reset button. The Marvell U-boot will then appear and all proceeds as normal.]

    Plugging in my GPS, which uses the ftdi interface, I get the following in /dev:

    usbdev1.1_ep00
    usbdev1.1_ep81
    usbdev1.2_ep00
    usbdev1.2_ep02
    usbdev1.2_ep81
    usbdev1.2_ep83

    Disconnecting, I get:
    usbdev1.1_ep00
    usbdev1.1_ep81

    And a message like this on the console screen: usb 1-1: USB disconnect, address 2

    So, for sure the plug and the OS recognize the device. I'm a little fuzzy about whether that means it works or not. I think not as I would have expected a tty.usbdev1.2_ep00 or something like that. I think I need to load the ftdi driver?

    [Edit - installed ftdi-eeprom that included libftdi but that didn't change anything in the /dev list]

    does lsusb see the device? I'm surprised it doesn't show up as /dev/ttyUSB*

    Bugbyte: Awesome! Can you post a link to the actual image you extracted onto the SD?

    I always forget that screen can work as a terminal. GDI, why do I forget that? It's *infinitely* less unpleasant to use than minicom.
