POGO Plug v2 (E02)

I just received a used pogo e02, I wanted to to convert this to a slim player device by putting debian onto it first.

I expected stock is to have been on the plug, but it seems to have corrupt is as of now, stock is not booting. No Pogo server running on ip address of device, my router identify it as "debian", can't connect with ssh, default password is failing.

I have serial console to it now, but stock OS has NO tool support it seems. cat / cd / grep all return as unknown commands.

I realize this is old device, so I tried to search first before makeing new thread, but My searches did not result in any answers to how to move from stock to debian. I only found topics asking how to switch from Aarch to Debian.

I did find a post from 2014 mentioning that from serial console you can set env and command boot from usb, but it was not enough details for me I suppose. I will keep at it.

I do find a couple posts and threads that say how to run Jeff's scripts to install Debian and update uboot. Bit they start with a running device with ssh access
All I have access to at the moment is serial console.

I bought this thing off of eBay, and description said working perfectly device. Not that I wanted a device running stock, but apparently I needed to start from there to enable ssh.

Might try to get e-bay refund.
Unless I find hope in restoring it with console cmd. And usb boot.

mrmazak,

Follow the instruction in the release thread:
https://forum.doozan.com/read.php?2,12096

and create the Debian rootfs on USB using Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2. You need to do step 4, since you are booting with stock u-boot.

Plug in this USB rootfs. Power up, interrupt serial console, and

setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
setenv load_uinitrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
setenv usb_boot 'mw 0x800000 0 1; run load_uimage; if run load_uinitrd; then bootm 0x800000 0x2100000; else bootm 0x800000; fi'
setenv usb_bootcmd 'run usb_set_bootargs; run usb_boot'
setenv bootcmd 'usb start; run usb_bootcmd; usb stop; reset'

And then,

printenv
boot

Please post the entire serial log here.

Here we go. You specified to do step 4 because of stock uboot. Makes me need to ask. Once I am able to flash new uboot, will I then update rootfs and undo step 4?

the 4th line , the one with the if statement was 'too many args"

Maybe I should try to make rootfs again. This line seems to indicate the usb stick is not recognized.

It is ext3, like Debian release thread says.

mrmazak,

This stock u-boot version does not support USB drive. So with this Pogo E02 if you cannot login with serial console because stock FW is corrupted, then there 2 alternatives (actually 3 but I don't want to muddy the water for now).

1. Boot the kernel with tftpboot. The setenvs posted previously will be changed to a slightly diffrent set of commands.

tftpboot will require you to set up tftp server in the box that you are using for serial console. It must be a Linux box.

2. Flash new u-boot in serial console, and boot into the Debian rootfs that you've created.

Flash new u-boot does not require further set up, you are ready to do that. The Debian rootfs must be as is after creation (Step 4 should not be done, since this is new u-boot).

Let me come back and post the command to flash in serial console.

2. Flash new u-boot in serial console, and boot into the Debian rootfs that you've created.

On 2nd thought, flashing directly like this has some risk. If for whatever reason it does not work, then the box will be bricked. And then you will need JTAG to unbrick.

Doing tftpboot is safer, in that you don't touch u-boot envs and u-boot itself during the attempt. After you have booted into Debian on USB, then you can flash new u-boot. At this time, everything will have been checked out. And so the flashing will have minimal risk.


Think about the above and let me know.

Tftp method might be better option. Gives more room for recovery before needing JTAG.

I have setup tftp server and found an example on using it to boot kernel, but have not tried it yet.

Has anything from this guide need updated?

This Pogo is failing to connect to my network. I find out.

During the tftp load it just keeps trying and then stops with message
Retry count exceeded; starting again
*** ERROR: 'eth1addr' not set



So I added setenv 'eth1addr' (router ip)

This stopped the error message, but still does not load from tftp.

Router log does not show any connection to box either.......
Correction: router log does show a connection. At least after I did setenv eth1addr (to same mac addr listed in ethaddr)

So what should eth1 be set as?

I have tried to match it to ip address
Tried match it to router address
Mac address
None of these worked.



Edited 1 time(s). Last edit at 11/25/2020 06:44AM by mrmazak.

You have eth only. Don't add eth1.

ethaddr is already set.

undefine eth1

CE:> setenv eth1addr

-----------------

Make sure your tftp server is on, the files are in the correct place, make sure your serverip is the tftp server's address



Edited 3 time(s). Last edit at 11/25/2020 09:40AM by daviddyer.

When I use term on other box on network, and I do tftp $server_ip
I get the tftp prompt
Then I command 'get uImage' the file is transfered

I can only assume that the tftpboot command should have been able to connect also.

Maybe need to chown the files or something. I'll try that after work.

Thanks

Try it in a few more steps.

set serverip, ipaddr, put your usb flash drive (rootfs) to the usb port of pogo E02

then

tftp 0x800000 uImage (the one with dtb built-in)
tftp 0x1100000 uInitrd
bootm 0x800000 0x1100000

Yes, like David said. Dont use command that does not allow you to see where it failed in each step.

The box MAC address must be ethaddr (ethaddr1 is irrelevant). So your settings are already correct:

ethprime=egiga0
ethact=egiga0
ethaddr=00:25:31:02:F6:64

And you can also test the server connection before do the tftp transfer.

Assuming your router is x.x.x.1, and your tftp server box is x.x.x.y, then

ping x.x.x.1
ping x.x.x.y

And then do

setenv ipaddr x.x.x.x
setenv serverip x.x.x.y 
tftp 0x800000 uImage
tftp 0x1100000 uInitrd

fantastic. I of cource made a mistake.
I cp the kernel files to "tftproot" folder, and servers root is setup in "tftpboot" folder.

fixed that and kernel loaded, but is halted at "booting Kernel"

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

I will leave it here for little time and see if it gives any life signs.

no progress.

the console stops receiving data. maybe the kernel files are not created right.

i did bad things t this thing now.

got frustrated and did

tftpboot 0x800000 pogo.kwb(short name I put for 2017 bootloader)

nand erase 0x0 0xa4fff

nand write.e 0x800000 0x0 0x80000

addresses found on openwrt flashing directions site. Then did reset. Now I get no response on serial console.

now i wil just stop, as i thin there is more more to do??? Maybe jtag, but that still needs console output i thought.

mrmazak,

Really bad move. You should have asked how to do the number 2 on my list

mrmazak,

This stock u-boot version does not support USB drive. So with this Pogo E02 if you cannot login with serial console because stock FW is corrupted, then there 2 alternatives (actually 3 but I don't want to muddy the water for now).

1. Boot the kernel with tftpboot. The setenvs posted previously will be changed to a slightly diffrent set of commands.

tftpboot will require you to set up tftp server in the box that you are using for serial console. It must be a Linux box.

2. Flash new u-boot in serial console, and boot into the Debian rootfs that you've created.

Flash new u-boot does not require further set up, you are ready to do that. The Debian rootfs must be as is after creation (Step 4 should not be done, since this is new u-boot).

Let me come back and post the command to flash in serial console.

Power down (pull out the power cord). And power up again. Does it now show any sign of life?

Yes, there is one quick flash of the LED when plugged in. Not from the big led(led4), from the lan port lights and one on the board(led3)

Lan port also has lights while connected

Too bad! you were very close to successful booting Debian in this post

u-boot was corrupted in NAND. So now it is JTAG time.

Yeah, I got ahead of my knowledge of this device.

I did setup jtag as the guide says.

https://forum.doozan.com/read.php?3,21789,page=1

But planed to do it from the pi itself. So I think 2 terminal sessions is correct?. Not three. So telnet step would not be relevant?


I don't have a 8 pin plug for the connection . And to buy the ones I found on amazon would be same cost as this device was $8.

So I am thinking about just soldering to the pins.


I did. Dry run the setup, and I got some errors in terminal about depricated settings. I aought to post them here and ask if it would be ok to continue.

Yes, post in that thread so joerg can help you.
