Then it does not seem to have UART booting support. I could not find Marvell Docs for 88F6282 either when I looked for it a few months ago. I think the GPL source might give some clues (might not in the u-boot code proper, but might be in documentation).

Hi!

Huh! I'm really ready to dig stock uBoot disassembly! ;)

And you're right - I dont find any Marvell Armada docs also.

But there is one thing I hope to be true: Armada 300/310 is more
like marketing re-naming, and >95% of specs is identical to kirkwood.
The main difference is ddr3 instead of ddr2.

The 0x200 block from mtd0 is identical to kirkwood - 32 bytes of main
header and 480 bytes of initial register content, more or less similar
to kirkwood *.cfg. Same DRAM registers, same window registers,
slightly different values (ddr3 differs).

I begin to think, that my ix2-dl is a hard thing! :D

Perhaps it is like the NSA325. WarheadsSE u-boot build confirmed this. We used the 88F6281 and a set of DDR3 values for it.

From Marvell's website it appears that Armada 300(88F6282)/Armada 310(88F6283) documentation requires an NDA with Marvell. :-(

Having recently looked at the specs on that device (impressive) and with it being the cheapest dual bay diskless NAS I have seen ($60 at Amazon right now), if you could figure out how to "Debianize" it that would be quite a feat :)

@bodhi @megov @rayknight

If You need some help with 88F6282 a0 i try to help !
I have one damaged DS212 ( synology ) with 88F6282 A0 onboard, but communication on UART is OK
I try to run kwboot with u-boot.kwb ( from complete with kwboot ) but my NAS after send file only suspend :( and only reset from power supply can help.
I don't have idea how to compile oryginaly u-boot from Synology GPL code.

If You need help with testing , i can help with my pleasure.

With best regards,
Robert

Sorry for my english, it's not my native language.

The Netgear Stora MS2110 can be added to the list of devices that can successfully be UART booted with kwboot. When recovering my Stora I used this 5 or 6 times successfully.

Non-working device at present is the Cisco ON100-K9 which has an 88F6282 A1 CPU running @ 1600Mhz L2 running @ 533Mhz. It consistently responds with:

root@Pogoplug-Pro:~/work# kwboot -t /dev/ttyUSB0 -b u-boot-db88f6282bp_400ddr3db_uart.bin
Sending boot message. Please reboot the target...-
Sending boot image...
0 % [+xmodem: Protocol error
root@Pogoplug-Pro:~/work#

I'm trying to use the kwboot method as I'm not able to determine how to stop autoboot with the stock U-Boot.
Re: UART Booting HowTo for Selected Kirkwood Devices

ray,

Netgear Stora is already on my list in the u-boot thread:

Quote

The latest u-boot image released here should be used for UART booting, if your box is the type that supports it (these do not: Dockstar, Pogo E02, iConnect).


Was u-boot-db88f6282bp_400ddr3db_uart.bin compiled with UART option?

Try:

After executing
kwboot -t /dev/ttyUSB0 -b u-boot-db88f6282bp_400ddr3db_uart.bin
and see
xmodem: Protocol error
Use the up-arrow to recall the command and run it again. Do this as many time as you can until it connects (if the bootROM supports UART booting, it will).

Re: UART Booting HowTo for Selected Kirkwood Devices

Build process for u-boot for Cisco ON100-K9 creates two files:

u-boot-db88f6282bp_400ddr3db_nand.bin
u-boot-db88f6282bp_400ddr3db_uart.bin

Nand is the image for booting from nand and uart is supposed to be image for booting from uart. Source is based from U-Boot 1.1.4 and the uart.bin image does have the appropriate 0x69 value at byte 0.

Trying your suggestion above I went through over 50 iterations of up-arrow recall command and run again with no success. When booting the internal U-Boot over serial the output 'Hit any key to stop autoboot:' appears to recognize the keyboard input, but does not stop the autoboot. The serial output is very noisy (i.e. lots of non-ASCII characters) and even shows noisy output at times when the power switch is off and even when no power is attached! I thought it might be an issue with the USB-TTL board or wires I was using, but I've tried 3 different USB-TTL boards and different wires that have never given issues with any other systems I've used them with.

Frustrating!!!!
Re: UART Booting HowTo for Selected Kirkwood Devices
July 21, 2016 02:00AM
OK, I've now located another serial port on the board! This one has clean output and successfully UART booted! The 4-pin header on the board is problematic. But just behind it are 4 holes with the pins in the opposite orientation that successfully UART booted the system!! I am also able to stop the NAND u-boot code after the 'Hit any key to stop autoboot' message. Below is the U-Boot output:

The other strange thing is that the source bundle from Cisco contains the source for U-Boot, but no kernel source! Any idea which dtb file I should attempt to boot with? I'm assuming I'll have to boot from SDHC as the USB does not appear to be recognized.

OK then:

1. Boot into stock OS and look at u-boot envs. Set bootdelay to 10. If this does not work then try 2. If this works, then try to interrupt it. Your serial console might have problem if you can't interrupt it during the coundown.

2. Look at the stock u-boot source, there should be a CONFIG_BOOTDELAY that needs to be set to some value. If this is not defined then it would expalin what you saw.

Update: congrats for figuring this out!

Hello,

Help I am just stuck at "Sending boot message. Please reboot the target..." too :(.

My steps:
- Start kwboot sudo ./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2016.05-tld-1.pogo_v4.mtd0.kwb -p
- Power up the Pogo V4/Mobile.
- Within 1-2 seconds when the spinning | starts slowing down (but not too soon), Control-C to abort kwboot, and recall the command, execute kwboot again.

My system: Debian
Re: UART Booting HowTo for Selected Kirkwood Devices

Miko,

With the Pogo V4, you will need to keep doing what do did: Control-C to abort kwboot, and recall the command, execute kwboot again. Do this as many times as you can until the handshake occurs. It might take as many as 20 tries.

Then you should check your serial connection, hardware wise. And check your serial module converter connecting to a different box. And examine the serial header on the Pogo V4. It should work.

No. That did not prove the connection is OK. picocom always give you this output (this is on the serial module converter end). Have you tried reversing TX and RX?

When you see this xmodem bad message, recall the kwboot command and execute it again. And repeat this sequence for serval times.

Some module converter need reversing TX-RX, some do not.

The PL3xxx needs crossing RX to TX. The CP2xxx does not.

Cool :) now you can boot into Debian using USB. See this to create the Debian 4.4 rootfs:

http://forum.doozan.com/read.php?2,12096

You don't need to do step 4 when you create the rootfs (you are running the latest u-boot using kwboot):

Quote

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

Hello,
First of all, I would like to thank you for your great contribution to pogoplug support.
I need your help.
My pogoplug is unfortunately bricked.
I can connect to my pogoplug mobile only via serial port:
./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2016.05-tld-1.pogo_v4.mtd0.kwb -p
I need to do this all the time when I want to use my pogoplug.
Sometimes USB with Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 works, sometimes USB storage disappears.
 usb list 
I do not know why.
I have tried to make rootfs on mmc, but when I run
 boot 
from sd card I always have output
Wrong Image Format for bootm command. Error: can't get kernel image!
I have no idea what I should do to make my pogoplug back to work.
I have 2 questions.
1. How can I flash Uboot via serial port and save it?
2. What should I do to boot debian from mmc?
I have only access to my pogoplug mobile via serial port.

kwboot and interrupt serial console, get the listing of envs

printenv


and post the entire serial console log here.

Looks like you have installed u-boot in this box before, and that was an older version of my u-boot releases. You also have a uEnv.txt in the SD card rootfs. What is the content of the uEnv.txt?

Your current u-boot envs (in NAND) don't have correct settings to boot with mmc, that's why it can't boot this SD rootfs. And your current uEnv.txt in the SD rootfs does not have correct settings either.

Try copy the u-boot default envs to your SD rootfs. This is the text version (in the u-boot tarball you have downloaded)
uboot.2016.05-tld-1.environment

Mount your SD card on a different box (assuming it was mounted as /media/sdb1)
cp -a uboot.2016.05-tld-1.environment /media/sdb1/boot/uEnv.txt
sync

Now try kwboot with this SD rootfs plugged in, and post the kwboot serial console here.

The second question is: How can I flash uboot to NAND via serial port. My pogoplug is not working without serial port - led is not blinking.
Re: UART Booting HowTo for Selected Kirkwood Devices
September 05, 2016 03:35PM
WIth SD rootfs plugged in, kwboot again, interrupt serial console and

run bootcmd_uenv
printenv
boot

Thank you for your time!
It works but only with kwboot.
Unfortunately, the pogoplug light wont turn on and I cannot boot from mmc or usb.
How to flash uboot to NAND?
Kind regards
