We're building the prototype hardware right now, and I've got a custom kernel (need >4 serial ports, shared IRQ) built and the PWL filesystem onto my CF. yay! I'm new to embedded/flash stuff, so sorry if this is basic. 1) /dev/sda1 contains the boot files, sda2 contains the OS. there's a sda3 partition on the rest of the CF card (128meg card), which I want to utilize as my own personal scratch space (this device reads from serial ports and stores logfiles for later upload). Can i just make ext2 on /dev/sda3, and mount it in sda3/etc/fstab as hda3? is it that simple? sda2/etc/fstab looks like: /dev/ram0 / ext2 defaults /dev/hda2 /mnt/flash ext2 ro,noauto,defaults none /proc proc defaults 2) anyone have some quick primers on setting up the dhcpd/pump and ppp with this distro? I'm sure I could noodle around and figure out what to put where, but it'd help if someone else had an example. ;) 3) java vm -- anyone gone through the pain and found a good one? (we're looking at Waba, I think) Any other wonderful words of advice would be great, so far I'm cruising along with only a few hurdles. I'm just beginning to get the hang of how things work in the embedded space.... oh! with CF media, can I just use dd to dump the entire card to a file, so I can duplicate it onto other cards? (ala a normal harddrive, block device, etc) thanks! -te -- Troy Engel, Systems Engineer Hockey. Kinda like Figure Skating in a War Zone.

(we're looking at Waba, I think) There are 2 versions of Waba for Linux. One is based on GTK, and the other one is based on PicoGUI (picogui.sourceforge.net). PicoGUI version is the one actively updated, like every 2 months or so. Me? I'm one of the developers (VM hacker ?) for Waba... I hope this helps. Sincerely, Isao F.

Our device is booting (yay!), now it's on to even more fun stuff. Do you have a methodology for installing the jvm, and where do you put your code? I was thinking of formatting and mounting sda3 (rest of CF card) as /opt, and putting the JVM and our code over there. See any downsides to that? Is it too slow to run right off CF, and should I be installing it with PeeWee, and having it load into ramdisk? thx, -te Ricardo Trindade wrote: > Hi, > > I'm using peewee on a 128Mb CF and sun's jre 1.3 fits in there. takes > almost half the card, but at least it's a full jvm > > ricardo > > -----Original Message----- > From: peeweelinux-admin@adis.on.ca > [mailto:peeweelinux-admin@adis.on.ca]On Behalf Of Troy Engel > Sent: quinta-feira, 30 de Maio de 2002 22:02 > To: peeweelinux > Subject: [Peeweelinux] newbie questions > > > Hiya folks, I have a few minor questions re: PWL if someone has a few > minutes.
