Have you tried with this guide? Recovering Intel Edison If Password Is Unknown. I've just tried it and worked well. Maybe you can give it a try. Just make sure the board reboots on step 5
Capturing and reviewing the console output while you flash the board should give you a hint where and why it's failing.
A few more things to consider:
- How are you powering the board?
- Could you be using an underpowered USB port to power the board or using a cheap USB cable with low quality conductors?
- If you're powering only via USB, have you tried connecting an external power supply to see if the failure is power related?
Google brought me here. I have exactly the same problem. The problem is that the file "ota_update.src" is missing:
boot > run do_ota
** Unable to read file ota_update.src **
Saving Environment to MMC...
Writing to MMC(0)... done
This problem is discussed here: Re: Custom Linux Image -- no ota_update.scr?
