The above envs tarball includes 3 files:

uboot.2016.05-tld-1.environment.img (the default envs image to be flashed on other Kirkwood box, not used here) 
uboot.2016.05-tld-1.environment (the content of the default envs in text format) 
uboot.2016.05-tld-1.environment.64K.img (small envs image to be flashed on HP T5325 and Dreamplug boxes only).

Please try UART booting with kwboot before flashing. Once it can be booted with kwboot, proceed to the installation instruction below.

./kwboot  -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.dreamplug.mtd0.kwb  -p

WARNING: Please proceed at your own risk. If you can't test this u-boot with UART booting then be aware of the risk of bricking the device should something goes wrong during installation (power outage, typos,..). And once the new u-boot is installed, it will not be possible to boot stock OS without further setup.


A. Installation from stock OS

Prerequisites

The Debian rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 must be prepared in advance on a USB drive on a single Ext3 partition and already mounted in this box before starting installation. The installation steps below assume that the following 4 prerequisites have been met:

NOTE: instead of the old rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (released when this instruction was written), you can also use the latest rootfs, e.g. Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2 and adjust the kernel version number in the instruction below.

a. The rootfs was extracted as is, and step 4 in the Debian rootfs installation is skipped (since we are going to boot with new u-boot, don't append DTB to uImage).
b. The tarballs uboot.2017.07-tld-1.dreamplug.bodhi.tar and uboot.2016.05-tld-1.environment.bodhi.tar have been downloaded and place in the /boot folder of the USB rootfs
c. The USB rootfs will be the only external USB drive mounted in the Dreamplug box (the drive that hosts the stock rootfs is also a USB drive internally).
d. The installation must be done while stock OS running.

Steps:

1. Boot into stock, mount the Debian rootfs, extract u-boot images, and prepare new uImage to boot with newer kernel.

1a. Boot into stock.

Power up the Dreamplug, and look for the dynamic IP assigned to it (look in the router webpage, or use network scanning apps such as Linux nmap or IOS Fing). Log in with SSH using credential root/nosoup4u.

1b. Insert and mount the Debian rootfs, and extract u-boot image and its env image.

mkdir -p /tmp/sdc1
mount -o noatime /dev/sdc1 /tmp/sdc1
cd /tmp/sdc1/boot
tar -xf uboot.2017.07-tld-1.dreamplug.bodhi.tar
tar -xf uboot.2016.05-tld-1.environment.bodhi.tar

1c. Prepare the new uImage using new kernel from the Debian rootfs. Replace stock uImage with it.

mkdir -p /tmp/sda1
mount -o noatime /dev/sda1 /tmp/sda1
cd /tmp/sda1
mv uImage uImage.stock
cp -a /tmp/sdc1/boot/zImage-4.12.1-kirkwood-tld-1 zImage.fdt
cat /tmp/sdc1/boot/dts/kirkwood-dreamplug.dtb >> zImage.fdt
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-4.12.1-kirkwood-tld-1 -d zImage.fdt  uImage
sync

1d. Reboot and login again to stock OS

shutdow -r now

Note that the Dreamplug now will be running the new kernel Linux-4.12.1-kirkwood-tld-1, but with stock rootfs.

2. Log in with SSH using credential root/nosoup4u. And verify that your mtds now show the following definition:

cat /proc/mtd

Expected Outputs:

dev:    size   erasesize  name
mtd0: 00080000 00001000 "u-boot"
mtd1: 00010000 00001000 "u-boot env"
mtd2: 00010000 00001000 "dtb"

3. Backup your current stock mtds for future restoration, should you decide to go back to stock

mkdir -p /tmp/sdc1
mount -o noatime /dev/sdc1 /tmp/sdc1
cd /tmp/sdc1/boot
dd if=/dev/mtd0 of=mtd0 bs=512k conv=sync
dd if=/dev/mtd1 of=mtd1 bs=64k conv=sync
dd if=/dev/mtd2 of=mtd2 bs=64k conv=sync

4. Flash new u-boot to mtd0

cd /tmp/sdc1/boot
flashcp -v uboot.2017.07-tld-1.dreamplug.mtd0.kwb  /dev/mtd0

Expected Output

Erasing blocks: 128/128 (100%)
Writing data: 512k/0k (100%)
Verifying data: 512k/0k (100%)

If there is any error, stop here and post for help in recovery

5. Flash u-boot default envs to mtd1.

cd /tmp/sdc1/boot
flashcp -v uboot.2016.05-tld-1.environment.64K.img /dev/mtd1

Expected Output

Erasing blocks: 16/16 (100%)
Writing data: 64k/0k (100%)
Verifying data: 64k/0k (100%)

If there is any error, stop here and post for help in recovery

6. And add fw_env.config to your stock OS. Modify envs to your Dreamplug specific settings. And set up netconsole.

6a. Add fw_env.config to your stock OS.

echo "/dev/mtd1 0x00000 0x10000 0x10000" > /etc/fw_env.config

6b. Modify envs. Replace MAC address xxx below with your box specific settings (they should be printed on the sticker label on the box case).

Note that the mtdparts layout are changed in the following fw_setenv commands. So when you reboot into Debian roots, the mtdparts will have a new layout.

/tmp/sdc1/usr/bin/fw_setenv ethaddr 'xx:xx:xx:xx:xx:xx'
/tmp/sdc1/usr/bin/fw_setenv eth1addr 'xx:xx:xx:xx:xx:xx'
/tmp/sdc1/usr/bin/fw_setenv arcNumber 3550
/tmp/sdc1/usr/bin/fw_setenv devices 'usb ide'
/tmp/sdc1/usr/bin/fw_setenv dtb_file '/boot/dts/kirkwood-dreamplug.dtb'
/tmp/sdc1/usr/bin/fw_setenv mtdparts 'mtdparts=spi0.0:0x80000@0(u-boot),0x10000@0xC0000(u-boot-env),0x10000@0x100000(u-boot-env-stock),0x10000@0x180000(dtb-stock)'

6c. Netconsole setup is still under testing - please do not use this 6c section to set up netconsole yet! Please proceed to 6d.

Setup netconsole envs (to activate later in Debian). Replace xxx below with your box specific settings. These are IP addresses that later will be used in connecting netconsole. ipaddr is the static IP that you assign to the Dreamplug. serverip is the static IP of he box that you will run netconsole verser later. If not sure, you can do these steps after booting into Debian rootfs.

/tmp/sdc1/usr/bin/fw_setenv preboot_nc 'setenv nc_ready 0; for pingstat in 1 2 3 4 5; do; sleep 1; if run if_netconsole; then setenv nc_ready 1; fi; done; if test $nc_ready -eq 1; then run start_netconsole; fi'
/tmp/sdc1/usr/bin/fw_setenv ipaddr    'xxx.xxx.x.xxx'
/tmp/sdc1/usr/bin/fw_setenv serverip 'xxx.xxx.x.xxx'

6d. Remove envs

/tmp/sdc1/usr/bin/fw_setenv mtdids 
/tmp/sdc1/usr/bin/fw_setenv partition 
/tmp/sdc1/usr/bin/fw_setenv machid

7. Done.

You can reboot the box. And SSH in at root@debian.local (or find the dynamic IP of the new Debian rootfs). The rootfs credential is root/root.

Upon reboot, on serial/net console, u-boot banner should show

I have successfully used the above uboot on an AppNeta Pathview microAppliance m22 which is a re-labeled Dreamplug. Only issue I had was realizing that the internal microSD card had a partition labeled rootfs which caused issues when trying to boot Debian from an external USB drive! Once I corrected that I successfully booted a Debian-4.12.1-kirkwood image from USB.

That's the normal behavior. Among all the drives, only one partition can have label rootfs while Linux is booting. The SD card should be unplugged during booting. Or to keep the SD card plugged in permanently, its partition must be renamed to something else.

I knew that only one partition should have the rootfs label, but I didn't realize the internal microSD already had a rootfs labeled partition. Removing the internal microSD card also isn't an easy task!

Hi,bodhi

When can we have the installation instruction for Dreamplug / Appneta m22?

Great!

Got some Appneta M22 from eBay. Seller is nice but USPS sucks.

You can only see 2 NIC ports, one USB port, one Jtag port. UART port is still there but there's no hole.You have to open the box to access it.

No optical output either. (I don't use this. I don't care).

All the ports on the back side of the NIC ports are gone / missing / not installed, Including eSATA, Mic/ audio ports, 2nd USB port, SD card reader.

Tried default password(s) of root and none of them work. (appneta.admin / password / AppNeta )

I removed the microSD card and mounted it on a Linux box, changed root's /etc/shadow and got root access to it. Looks like Ethernet port 1 is configured. I can ssh to it with root when I connect E1 to router.

Linux m22-VTfQ5 3.10.33-ani05 #1 PREEMPT Fri Jun 6 12:24:33 PDT 2014 armv5tel GNU/Linux

Now wait for instructions to flash the latest uboot. Maybe I will try to drill hole to access UART and install eSATA port.

Just connected serial port to RPi 0's serial port, kwboot, then flashed the latest uboot to my m22. Set ethaddr, eth1addr, boot debian 4.12.1 ok.
fw_printenv complains about crc error. Stopped uboot, printenv, saveenv, boot, fw_printenv still complains.



echo "/dev/mtd1 0x00000 0x10000 0x10000" > /etc/fw_env.config

fixed fw_printenv error.

David,

I'll need to find some block of free time to write the instruction.

Nevermind! I booted back to stock OS. So I was able to check this.

The installation inside stock OS is a little bit cumbersome. Stock kernel is quite old (2.6.x), and the SPI mtds are not exposed. With serial console, the installation is easy, but without it, not so simple.

daviddyer,

Thanks for reporting the problem with netconsole setup. I'm looking into it.

In the mean time, please do not set up netconsole (skip section 6c).

-bodhi

bodhi's corner (buy bodhi a beer)

All,

Netconsole driver is common to all boxes. But this problem seems to affect the Dreamplug only.

Please try this work around.

Interrupt netconsole at countdown, and run these commands

setenv reset_console 'setenv stdin serial; setenv stdout serial; setenv stderr serial'
setenv bootcmd_exec 'run load_uimage; if run load_initrd; then if run load_dtb; then run reset_console; bootm $load_uimage_addr $load_initrd_addr $load_dtb_addr; else run reset_console; bootm $load_uimage_addr $load_initrd_addr; fi; else if run load_dtb; then run reset_console; bootm $load_uimage_addr - $load_dtb_addr; else run reset_console; bootm $load_uimage_addr; fi; fi'
boot

This will let the kernel boot normally. However, some dmesg output will be lost at the beginning of the boot log (if you have configured netconsole in Debian and expect to see more). This work aoround does not affect serial console, so you can choose to set it permanently once you're satisfied that it works well for netconsole.

I have Appneta M22, which is a simplified version of dreamplug. Debian boots OK with the new u-boot, but netconsole never worked. Since it is not easy to access the serial port of M22, I did not do any further research on this issue. Dreamplug has kwboot / serial, even netconsole is not working, it is not a big deal.

When you say it does not work, please describe. Were you able to connect netconsole and interrupt it? How far you got?

Nothing shows up on the netconsole... You can just see the command you typed in on the netconsole.

So I tried to ping the M22 from netconsole computer, and I got no reply from the M22 during the whole booting process. I can only get reply from M22 after the booting is finished.

Debian boots ok.

daviddyer,

That's either something wrong with your setup, or something peculiar about the M22.

On the Dreamplug, netconsole starts OK, and load the kernel. The kernel starts running, but later, it stuck somewhere because of console conflict. So my workaround above is to reset the console to serial to force it back to boot with serial normally.

-bodhi

Well, I found out what's wrong with my M22... I followed the instructions exactly, but preboot is actually not defined. After I defined preboot 'run preboot_nc', my M22 acts like your dreamplug with the netconsole on -- Netconsole starts, I can stop autoboot on netconsole, but debian stucks somewhere after "starting kernel ...." shows up on netconsole


So I just 'setenv preboot' again.

daviddyer,

If you are interested, try the work around I posted above.

Well, I bought this M22 trying to replace the good old dockstar... but unlike dreamplug, it doesn't have
SATA--which is I really want. So I think I will just put it there for some time, until I can find parts and try
to add sata to it. :P

Maybe I will cut a SATA cable and connect it to the board directly. :P

That would be a HW mod I'd like to add to the Wiki thread!

Well, after checking / comparing the board with Dreamplug board pictures carefully, I decided to give up. A lot of components near the SATA port are also missing on the M22 board... Not just the esata port only. So it is just an enhanced version of dockstar with 512MB memory, better yet with kwboot capability.

There must be multiple versions of the M22 then as the one I have which I created the WikiDevi entry with is identical to the V10R1 Dreamplug I have.

Ray

Yes. The M22 that I saw on eBay are all barebone like that. For their low cost, 512MB and Gbit Ethernet in a complete box is good. Too bad it lacks eSata.

Upgraded my DP following this procedure but on reboot, the MAC addresses are incorrect.

Attempting to correct them at the u-boot prompt gives;

## Error: flags type check failure for "ethaddr" <= "f0:ad:4e;00:b6:3e" (type: m)
## Error inserting "ethaddr" variable, errno=1

printenv then refuses to display the hardware address variables at all.

They do though, afterwards, appear to be correct from within the OS.

Anybody anyb clues?

";" and ":" are different.

"f0:ad:4e;00:b6:3e" is NOT a valid ethaddr.

Therefore, ethaddr was unset in environment. that why "printenv then refuses to display the hardware address variables at all"

But since you did not do "saveenv" in u-boot, the old address might still be there.

I think that ';' was a typo, I'll double check.

I didn't do a saveenv as the setenv had failed. Will double check and respond.
