Is the blparam broken?

[cscw]

The model of my pogoplug is pogoplug video. I installed archlinux without problem according to http://archlinuxarm.org/platforms/armv6 ... provideov3. For some reasons, I planned to reverse this one to the original system. I searched on this site and found a reverse script(viewtopic.php?f=29&t=1114). I downloaded and executed it, with the error message that my pogoplug video was an unsupported model. I analysed the script and found the problem was that: it couldn't get the infomation of my pogoplug video because of the blparam. What makes me confused is that, my pogoplug video boot successfully all the time. Doesn't the kernel use the parameters of blparam to control boot device? If it's broken, why my pogoplug video boot normally?
Thank you very much in advance!

This is the original blparam, can't execute either.

Does anybody know how to figure it out? I appreciate your help!

The video model has been recalled as some caught fire.

blparam can be used to control the bootloader (u-boot) configuration from a running operating system. It is not required for booting, as u-boot has access to it's own environment (of course), and passes the command line arguments needed to the kernel.

It's not a biggy unless you want to go back via the oxnas-revert.sh script, but you can perform the same steps via a serial console.
