[Resolved] stock pogoV4: fw_printenv gives "Bad CRC: using default environment"

[EDIT2: I should have just read through (or remembered) all the uBoot instructions ... The following completely resolved my question:

Save envs (stock OS might not have fw_printenv, so try blparam): 
fw_printenv > current_envs.txt
or
/usr/local/cloudengines/bin/blparam >  current_envs.txt

Feel free to delete this post (or tell me to) unless you think it will help another stumbler, but just for completeness I'll post my blparams:

I apologize because I'm pretty sure I've dealt with this issue before, but I can't remember the (probably trivial) way around it:

Stock PogoPlug V4, I managed to enable SSH via serial connection and am just starting to try to install uBoot. I downloaded the (current, I believe) U-boot flashing utilities and get the following error on fw_printenv:

/tmp # fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5
baudrate=115200
/tmp #

Is this to be expected because I'm on stock? Do I need to be using blparam instead? Are my questions even sensible?


[EDIT: as I suggested in next post, I'm guessing that I can just ignore this and jump to extracting the uBoot archive. If that's right, don't waste your time reading below this line]

For reference:

/tmp # cat /etc/fw_env.config

# Notice, that the "Number of sectors" is ignored on NOR.

OK ... likely I'm being dense ... can I just ignore this and skip to extracting the uBoot archive?

Yes, you are in stock OS.

Before you flash the default u-boot envs image, that area can not be used with fw_printenv.

But you can use blparams to list them. Even if you cannot list them, it is OK. Go on to the next step.

hughe,

Glad you've resolved it! let me know how it goes with flashing new u-boot and envs images.

All went fine - I was pleased that (thanks to your buckets of help on other devices) I was able to get this one up and running with ONLY THIS ONE stupid question (that I figured out before you could even answer - don't think that's ever happened before). I was able to deliver a fully functioning Debian + Samba box to my sister so that she can use it as a home server.

I'm now 5-for-7 in getting Pogos up and running Debian. I still have two Mobiles that I can't get a solid serial connection to (I get nice looking text on my screen, and I can interrupt the autoboot with keystrokes if I'm fast enough, but the characters I type are either not transmitted or not interpreted correctly - my screen shows 80% garbage characters and 20% the keys I'm actually typing. But I'll post that in a more appropriate spot if I can't fix it soon.

Thanks again - I didn't need your help on this one, but only because you've given me so much assistance in past installs.
