Hi Matt,

IN THEORY, the system should flash it and then power off. You'll see the caps lock led blink 3 times then it'll shut down. At this point take the SD out... flip the DIPs back, et voila. However if the system is constantly rebooting and flashing, you have those 3 blinks to basically kill the system (yank AC with no battery) or it will be halfway through a flash update and NOR will be invalid again.
I run the updater-sd-card successfully at one time and it proceeded as you described it, caps lock blink 3 times then shut down.
If we're at the point we're having more trouble at this point please give me a nudge and I'll create a solution for rescues that will suit your exact situation.
I am curious, how did you get to this state in the first place?
My inexperience with writing u-boot scripts but me in this situation. I wanted to write my own u-boot script. Now when I boot the caps lock is not blinking instead there is a steady bright light.
I haven't double checked what I did to make this happen yet. I used setenv with invalid bootargs but I didn't store them. This weekend I will make a new attempt bringing it back to life. I don't have a arm development board at home to test patches on so I thought I may use this one for it. I just need to get familiar with the boot/flash procedures first :)
Thanks for you detailed instructions.

If I mess up the u-boot in my efikamx smart book how can I install a new one? I tried booting with an SD-card image from http://www.powerdeveloper.org/asset/by-id/116. I guess this only works if I have a working u-boot in place.
I don't have the serial/JTAG connector. Is this what I need in order to recover?
There is a series of DIP switches in the back panel (where you plug the debug cable); depending on their positions, the board will boot from SD, micro-SD or from flash. You can create a "replace all my flash contents with a known-good u-boot" SD card with the bits provided by genesi.
