Awesome, thank you for the info!
Not sure if you saw this by the way, but just for my curiosity for when this happens again (it will I'm sure, I just started RMA a few days ago after giving a flash a shot from microsd and usb3):
> Is it read in one go upon init? Or does it start the firmware which then loads it's configuration from SPI during init (two separate reads)?
> Is it stored at the beginning or the end of the flash?
I'll keep track of which settings I've changed this time and do it in stages. This way I'll find our approximately which settings cause this soft brick so you can fix it.
I'll respond back here. Keep in mind this will be a while, because I haven't yet gotten a response, I'm sure just due to the holidays, then I have to wait for a shipment and such.
Oh, and I read in another post that a debug board is not available? Is this true?
If the card is not available:
- Can we make it available so I can fix the unit myself and in addition get access to i2c peripherals?
I somewhat expected that this unit would be treated like the Joule, eg with everything out in the open, since it's development kit hardware, and having the ability to debug would be extremely beneficial!
For instance, I wouldn't have to do an RMA right now, plus I'd get a cornucopia of features I wish I had right now, such as i2c!
During BIOS boot up, the boot up code may read and write the configuration data many times by items.
the SPI Flash size is 8M bytes, BIOS firmware with nvram area is the upper 3M bytes.
And please do not change the OS boot options in BIOS, the Euclid device doesnt support Windows, only support ubuntu.
Thanks for the info. I was asking to see where I could fuzz to break the CRC so it will boot, if I decided to go that route (I didn't, I'm still trying to create an RMA request)

I haven't used windows in many years at this point, but thanks
Sorry, it's taken me so long to get back to you. I have been out for the holidays.
Unfortunately, Intel cannot release the debug card.
Are you still having problems creating the RMA? If you need help, I can intervene on your behalf.

Hi, I have the same problem as described in this post, so I think I should ask here before opening a new discussion.
What I did: I wanted to reinstall Ubuntu on the Euclid (link), so I tried to use the boot manager to select USB Device and enabled Fast Boot and UEFI Secure Boot (I don't remember exact text on the screen, but those options were disabled).
After saving the settings and reboot, I faced the same issue: no HDMI output, nothing on UART kernel log output, there is green light and USB hub is on.
One thing I noticed: When the green light is on, if I press both buttons on the Euclid, I can get some output on UART:
But when I release the button, nothing happens.
I hope this can shed some light on the problem. Is there something I can try besides RMA the product?
Thank you for your time,
Unfortunately, without HDMI output there is no way we can guide you through a process to fix this. It seems that your only option is to RMA.
If you wish to return your Euclid for a refund, please login to https://click.intel.com/ and go to My Account -> My Orders -> Return or Replace Items and select resolution type "Refund". Follow the prompts for required information and click Submit.
