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.

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. > -- > Matt Sealey <m...@genesi-usa.com> > Product Development Analyst, Genesi USA, Inc. > > > > On Tue, Jan 18, 2011 at 4:02 AM, Loïc Minier <loic.min...@linaro.org> wrote: >> On Tue, Jan 18, 2011, Per Förlin wrote: >>> 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.
