1  Hardware and U-Boot firmware / Hardware / plug stopped booting - Bad Magic Number on: May 06, 2009, 07:00:04 AM
Hi,

my plug was working fine for a week or so but now it fails to boot.
When I watch the boot via the serial console the last line is "Bad Magic Number" when loading the kernel.
When I run "bad nand" it reports about 20 blocks.

I'd followed the steps on New_Plugger_How_To guide on the wiki and everything worked perfectly, detecting the DHCP server on my router and getting its IP address etc.  I was rebooted (hard and soft) several times with no problems.

I've made no changes since following the guide.

I'll try reinstalling everything but I'm worried now about reliability.

I just received my plug and spent today getting it setup.
I plan doing some general IO using the flexel chip and the usb board.
Very cheap on ebay.

It has a few preconfigured modes including one with 2 14bit A2D inputs 8 general IO ports and a couple of analogue outs.

My biggest problem with this is that the plug has only one USB port.
I want to use a USB 3G broadband modem for network access and I don't want to have to use a usb hub.

I'm sure I read somewhere in the docs that there are two USB ports - is one of them simply missing a socket?

I wonder if the plug can provide sufficient power for the USB modem too.
