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.
