Problem booting Pogo v4

Hey Bodhi,

I recently found my lost Pogoplug 4 and managed to mess up upgrading it from 3.18.5 to the latest 4.8. I tried to roll back my changes but booting is stuck at starting the kernel regardless of which one I try to use.

Starting kernel ...

I've upgraded uboot during my troubleshooting and noticed that my /proc/mtd has two uImage lines. I'm not sure if this is the problem but I also don't know how to remove the uImage2 line to actually troubleshoot it.

~ # cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00200000 00020000 "u-boot"
mtd1: 00300000 00020000 "uImage"
mtd2: 00300000 00020000 "uImage2"
mtd3: 00800000 00020000 "failsafe"
mtd4: 07000000 00020000 "root"

Any insights as to why my Pogoplug is getting stuck starting the kernel will be appreciated.

Thanks,
Strix

Strix,

Boot again. Interrupt netconsole and

printenv

and then

boot

Post the entire log here.

That uImage2 is not relevant. As a matter of fact, only mtd0 is used (where u-boot is), the other mtds are not used at all.

Your SD card rootfs, even messed up, has valid kernel files. That got you to the "Starting kernel ...." point. After that netconsole will not show anything (unless you have booted into Debian and set it up further).

Hi Bodhi,

When I interrupt netconsole, no commands seem to work. Typing printenv and hitting enter didn't print anything. Netconsole seems to only be interrupted by the enter key. Using other keys didn't stop the countdown.

Since you pointed out that netconsole stops at "Starting kernel" I tried to see if rolling back my kernel to 3.18.5 worked and it did. I then followed the steps for installing 4.8.3 (I noticed I had grabbed the 4.8.0 kernel before). Before I rebooted I got the printenv in case the boot failed.

While 3.18.5 was running live, when you installed kernel 4.8.3, did you append the DTB to uImage? You should not. Your uboot envs boots with separate DTB.

It not sure, mount this USB rootfs drive on another Linux box, and check:

ls -lart /media/sdb1/boot

(If the usb was mounted as sdb1, it not then adjust the above command to use that drive letter).

I did not append the DTB, I followed step 4a and then step 5.

I'm using an SD card rootfs.

Strix,

I see. This is the problem: you did not flash the new default envs image (the new default envs have everything loaded automatically). So you envs are still old. And the set of old envs did not load the DTB.

bootcmd_mmc=run mmc_init; run set_bootargs_mmc; run mmc_boot
mmc_boot=mw 0x800000 0 1; run mmc_load_uimage; if run mmc_load_uinitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi

Your USB envs looks OK.

If you can't interrupt netconsole to fix the mmc-related envs, you can prepare the USB rootfs and boot with it. And then flash the default envs following the instruction in step 8:

Quote

8. Flashing default u-boot envs image:

As described in step 1, u-boot envs must be defined in etc/fw_env.config as

# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

A special section (B. Flashing default u-boot envs image) about flashing default u-boot envs is included at the end of this installation procedure. Please follow the instruction in this section B to perform this step before continuing with step 9.

However, netconsole input problem still need to be solved. Since you don't have serial console, this is crucial to have in case you ever have messed up the u-boot envs too much.

Netconsole is a little tricky. Here is the format of the nc command I usually run from another Kirkwood box (if you use Linux laptop/desktop with Ubuntu or other distro, its nc might have different syntax):

nc -lup 6666 192.168.1.20 6666

So I need to remove the mmc related envs?

I was running netconsole from a linux box from a cygwin terminal so maybe that's why the interrupt won't work, I'm going to try it again from a linux terminal instead.

Strix,

> So I need to remove the mmc related envs?

No need to. They can still be set, but will not be executed. Remove the SD card. And plug in the USB rootfs.

Yes. This would be best. If you want to do this and fix mmc envs on-the-fly then a few envs need to be added/modified temporarily at the prompt (it wont hurt if you do not run saveenv)

I don't have a USB rootfs, my setup was with an SD card rootfs. Will this be configurable to boot using the SD card?

I think the nc issue is with my distro nc. Using the command above gives a "Cannot assign requested address error". I was using the other nc method by running:

nc -l -u -p 6666 &
nc -u 192.168.1.20 6666

Of course it can be. But you need netconsole or serial console to do that. So without either, you need to create a USB rootfs to boot with and fix it after.

On 2nd thought, there is a different way. Easier.

Could I just rollback my kernel to boot into 3.18 and fix it as part of the upgrade to 4.8.3?

Of course. If you can boot 3.18.5 Debian rootfs, then in Debian, flash the default envs image that comes with u-boot-2016.05-tld-1 (and adjust the envs to your box using the instruction).

I found the problem I was having with nc was it was the openbsd version which doesn't allow the use of the 'l' and 'p' flags together.

I think I messed up the mtdparts setting by accidentally setting it to:

mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

instead of:

mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

Device won't boot at all now.

Here's the whole printenv before I rebooted

The mtdparts env will not affect booting at all. And your envs look fine.

Please post your netconsole log here.

Netconsole isn't getting anything from the pogo. The light on the front of the device isn't lighting up at all either.

When you recycle the power, does the LED light flash and then went out? or no light at all the whole time?

None at all the whole time

Strix,

Ok then, you will need to connect serial console to fix this. If the LED does not flash at all, it is a symptom of u-boot image on mtd0 was messed up. Do you have a log of what you did? pls post here.

Hi Bodhi,

I thought you might say that. Ok, is there a serial cable I can order on amazon that I can use? Or a cable you recommend?
If you have a link to instructions for how to connect to the pogo serial that would be very helpful.

Here's the log of commands I did last.

I have extra ribbon cables similar to this: https://goo.gl/c4eZo8
Can I use them in place of getting the "Micro Mini.JST 2.0 PH 4-Pin Connector"?

You need to either:

1. solder the JST header into the board,

2. or use some sharp pins (such ones used in shirts box) to temporarily connect to the solder buttons on the board (they are soft enough that you can push the pins in).

Hi bodhi,

USB serial part came.

What's next?

Get the latest Pogo V4 u-boot from this thread:
http://forum.doozan.com/read.php?3,12381

And set up UART booting using kwboot.

Quote

Important Note: If possible, try to test this boot image with UART booting before flashing to NAND. See davygravy's UART booting using kwboot instruction here in this thread. 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).

To download ARM kwboot binary for UART booting at Dropbox

kwboot-2016.05.tar

Once you can kwboot and run u-boot, you can boot into your current Debian rootfs on SD card. You will need to modify some u-boot envs at u-boot console before it will boot. But let's get that kwboot running and we'll go from there.

Ok I got the system booted via kwboot.

Do you need any of the output?

Of course, the best way for me to help is the log of what you have (without that, it will take time rereading many posts about where you are).

Boot with kwboot, interrupt at count down and get the listing of envs at the prompt.

printenv

And then please post the entire serial console log.
