Zyxel NAS540 bricked?

[AndrewCz]

Hello all, hope you are well.

Recently, I followed a guide[1] to reflash my Zyxel NAS540[2] in order
to put Debian on it. I'm pretty sure I bricked it and am just looking
for confirmation.

I seem to be running into a bootloop where it will restart every two
minutes or so. At least that is what seems to be indicated based on the
frequency of the front panel lights lighting up. I reflashed the 'env'
and 'kernel2' sections of the NOR flash, but neither went the right way.
I can dive into the specifics if necessary. However, my concern is that
I was unable to receive any output from the serial connection.

Given that the barebox 'env' may be corrupt as well as the kernel, is it
correct to expect that there would be no serial output? Thanks for your
consideration in this matter.

The Zyxel NAS540 seems to have a Freescale QorIQ LS1024A SoC. There is
no mainline barebox support for this SoC, so Zyxel must have created
their own patches. I know nothing about these patches nor about the SoC,
so I'm sorry I can't really help you.
What I can say is that normally barebox outputs stuff out of the console
even without valid environment or kernel. That is configurable though,
so I can't tell for sure.

Sascha

And evenif we would like to help you zyxel did not provide to source code of
theur barebox they modified. Just the source code of the 2011.06 version.

So you will have to request them and if they refuse we could then force them
to release it as Copyright holder.

Best Regards,
