31  Hardware and U-Boot firmware / Hardware / Trying out other kernels on the Dreamplug on: February 24, 2011, 05:35:43 PM
From what I read we can:

1) go to sheeva-with-linux.com and get an uImage file for kernel
2) get the modules.tar.gz for
3) load these onto a USB stick with the root.fs.img file that we generated from our dreamplugs internal sd card

then we could do something like (by changing our boot arguments)

usb start
fatload usb 1 0x6400000 uImage

I think this would allow us to boot with the newer kernel and then we would log in as root, cd / and extract modules.tar.gz from the USB stick using tar xvf

Is that correct?
32  Hardware and U-Boot firmware / Hardware / I got my Dreamplug from GS on: February 24, 2011, 05:25:47 PM
The internal SD card is 1 GB.
33  Hardware and U-Boot firmware / Hardware / u-boot is the problem on: February 24, 2011, 04:55:30 PM
I am a bit of a newbie so please forgive any mistakes I might be making. I want to summarise what I think the current situation with the Dreamplug is.

Right now we can boot up the DreamPlug and

1) back up the uImage file in /media/usb to a USB drive (say /media/usb4)

2) do "dd if=/dev/sda2 of=/media/usb4/rootfs.img bs=4M" to back up the root file system as an image file

This backs up the uImage file and the root file system.

But we don't have a way of backing up u-boot and there doesn't seem to be a way of getting a backup u-boot image file (yet) from GS.

Right now we can install gcc and then download the latest u-boot sources and then compile a new u-boot. But right now we don't have a way of installing in onto the Dreamplug or restoring the old u-boot if the newer one does not work properly.

Did I understand the issues correctly?
34  Hardware and U-Boot firmware / Hardware / Thanks! on: February 24, 2011, 12:00:16 PM
Thanks! I'll try it.

I was thinking of trying out fedora on the dreamplug. I think it would require using the fedora kernel tho and I am not sure that fedora would have the drivers for the dreamplugs devices (sound, esata, spdif...)
35  Hardware and U-Boot firmware / U-Boot stuff / Re: problems with custom uboot build on: February 24, 2011, 06:30:56 AM
I think you might want to use "bootm 0x6400000"
note that there are 5 zeros after 64
you can check the address to use by checking the default value that you get from printenv in u-boot
36  Hardware and U-Boot firmware / Hardware / Dreamplug u-boot update needed to allow booting from an SD card on: February 23, 2011, 08:53:51 PM
I was able to backup the internal SD card to a USB drive. Then by changing the u-boot parameters I was able to boot the device from the USB drive. I really want to be able to boot the drive from an inserted SD card. The current U-Boot does not allow this so now I have to figure out how to upgrade U-Boot to a newer version.

*SIGH* Does anyone know how to do this? I know there is  quite a thread on this forum about U-Boot but I haven't found a definitive solution.
37  Hardware and U-Boot firmware / Hardware / Dreamplug U-Boot on: February 21, 2011, 05:02:52 PM
I got my JTAG unit running from Mac OS X. This took a bit of googling and some minor hacking to get working. I found an app called "goSerial" that works well with the FTDI USB device in the Dreamplug.

I got into u-boot and tried a few things.

the version command shows:

U-Boot 2010.06-02334-g8f495d9-dirty (Dec 21 2010 - 15:27:37)

I do not know what version of u-boot this is.

printenv results in

bootcmd=date;setenv ethact egiga0; ${x_bootcmd_ethernet}; setenv ethact egiga1; ${x_bootcmd_ethernet}; ${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;
x_bootcmd_usb=usb start
x_bootcmd_kernel=fatload usb 0 0x6400000 uImage
x_bootargs_root=root=/dev/sda2 rootdelay=35
burn_spi=sf probe 0; sf erase 0 d0000; sf write 1000000 0 d0000

Environment size: 594/4092 bytes

Now I have to figure out how to clone the internal drive to an SD card and have it boot from that card. Note that the bootdelay is 3 second! You don't have much time to hit that key to get into U-Boot!
38  Hardware and U-Boot firmware / Hardware / Heat Issues on: February 19, 2011, 05:45:11 PM
I've had my dreamplug on for more than 24 hours and it is just a little warm. No overheating issues so far.

Of course it wasn't actually doing anything. I was just ssh-ing into it now and then to confirm that it was running.

When I can run it as a squeeze server I will let you know about any heat issues.

40  Hardware and U-Boot firmware / Hardware / Re: I just got my Dreamplug on: February 17, 2011, 12:06:53 PM
I have ordered a JTAG unit and will have it in a few days.

I plan to back up the internal storage to another SD card. Then I want to modify uboot to have the dreamplug boot from another external SD card.

I want to use the dreamplug as an access point to serve music to the Squeezebox devices in my house.

I don't want to start hacking on the box until I have a good backup / recovery strategy so that if I mess things up I can quickly get back to a good state.

I am concerned to hear that there don't seem repositories for images for the kernel and root filesystem.

I will run the unit overnight and let you know if it gets hot.

Oh yes, the unit did not come with any documentation or any cd that might contain backup images / software / docs.  8(

Unfortunately I forgot to order the JTAG unit to use with it! Doh!
I had heard that using ext2 is better because the journaling with ext3 was undesirable

Can anyone recommend a JTAG unit for this device other than the one form globalscale?

Thanks for any help

/media/usb and /media/usb0 contain a file called "uImage"

it looks like we can back up /dev/sda1 to back up the internal hard drive

since there isn't a usb port to access the device via a serial terminal I am not sure how we could then access uBoot to tell the device to say boot from an SD card that might contain debian 6.0

cat /etc/debian_version gives the following result:


There is no "/dev/mmcblk0" device. I am not sure how the internal disk is represented in /dev

There does not seem to be a port to hook up to a usb cable to get into the uBoot environment

I guess I should be able to update the internal card to a USB thumb drive or SD card
44  Hardware and U-Boot firmware / Hardware / I just got my Dreamplug on: February 10, 2011, 05:54:39 AM
I just a Dreamplug. Here are some initial observations:

1) uanme -a shows:

Linux sheevaplug-debian #1 PREEMPT Sun Dec 5 22:56:10 CST 2010 armv5tel GNU/Linux

so I think this is lenny

2) i did apt-get install usbutils and lsusb reports:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

3) ifconfig -s shows:

uap0       1500 0        95      0      0 0           103      0      0      0 BMU

4) using my phones wireless network browser I noticed that the Dreamplug showed that it was hosting a wireless network named "Plug2-uAP-50a0"

I am wondering how I can back up the SD card in the device and then if I can update the system to debian squeeze.

Does anyone know how to do this? Thanks for any help
