Not strictly booting - halt

[akc42]

I have nicely got my Sheeva plug set up with Debian, both now in the flash memory and on an inserted SD card.

I have one little niggle.

I type "halt" as root, and the system shuts down, but does not power-off.

If I manually power off and then power on again I find that I cannot ssh into the machine, even after waiting a while.  I then try and connect with USB console port and find that the u-boot is sitting awaiting input. That is, the machine has not booted, but somehow ended up in the command prompt.

Its a bit of a chicken and egg situation to try and debug, since as soon as you power off the link to the console is cleared.

A reset when in the boot prompt does cause a reboot and automatic load of the software, so I think my boot environment parameters are ok

Anyone any ideas of how to fix?

All the symptoms that you describe are "by design".

When you say:

u-boot is sitting awaiting input

are you sure that U-Boot is responsive to your commands? "Halt" should be just that, a shutdown to a state where only a repowering, or reset switch will bring the plug back up.

When I am halted, using either screen or cu through to the console nothing happened.

In the past, I have powered down and powered back up and waited to ssh back into the device.  WHen that failed (no route to host) I connected again with cu and found  u-boot sitting there awaiting my input.

However, I just tried it again and it seems to be alright now.  I can halt the machine from an ssh session, power down and power back up and then await a few seconds for it to boot and ssh back in again.

So it seems to be OK now.  Sorry for the noise.
