Can't proceed past Gigaboot (on Intel NUC7)

[Ron Even]

Hi

I'm trying to install Fuchsia on an Intel NUC7CJYH.

I've built everything both in workstation and core modes, and on macOS and on Ubuntu, but no matter what I encounter this same screen when plugging in the USB flash drive created by fx mkzedboot.

As far as I understand Zedboot is the next stage after Gigaboot, but I can't seem to pass it. I do see it complains about many errors, but don't know how to solve them, as I did everything exactly like the guides say (and even bought NUC7 especially to make sure it works...).

This is what the screen shows (sorry for the somewhat bad quality)

EDIT: After some trial and error, I found:

fx make-fuchsia-vol

that probably worked better, and now looks like the partitions are there:

However, it still doesn't boot (I tried all slots and the result is the same, just with the corresponding letter...)

I hope someone can help me understand what's the problem

Thanks

It looks like the kernel has started to boot, but you have no display.

I believe your GPU is not listed here: https://cs.opensource.google/fuchsia/fuchsia/+/master:src/graphics/drivers/msd-intel-gen/src/device_id.h

Hi Ron,

I think your GPU is 'Intel UHD Graphics 600' (device ID 0x3185.) Craig might be able to help you determine if it's supported or if there's a way to get it working.

If you have a way to get logs out of the device either via serial (fx serial) or over the network (fx log) that might help.

That appears to be a Gemini Lake chip, one of the older low power variants from Intel and there are likely some graphics driver incompatibilities vs the supported Kaby Lake/Amber Lake.

A while ago we discussed, but did not move forward with adding support for the generation previous to Gemini Lake with HD Graphics 500.

So unfortunately I don't think there is a quick fix to get working graphics on this hardware.

Thank you very much, I also checked and it seems that my NUC really has Intel UHD Graphics 600.
Can you tell me which exact NUC model I need so that it will surely work? (Or if there is a better, maybe more compatible alternative?)

Thanks

Hi Ron,

you can find some recommended hardware list on fuchsia.dev: https://fuchsia.dev/fuchsia-src/development/hardware/intel_nuc

To surely work, pick a NUC with graphics listed in the device_id.h file.

Hello Ron,

To add on to others, I looked through our documentation, and it's pretty easy to miss that we only support a subset of NUC7 devices. I've filed https://fuchsia-review.googlesource.com/c/fuchsia/+/534722 to make sure others don't encounter the same problem as you.

[Justin Mattson]

The NUC7i3DNHE seems to contain the Core i3-7100U which contains HD Graphics 620 identified by 0x5916 according to wikichip and that appears on the device_id file. I think this is probably the lowest end, support device according to the docs I can find.

Thank you so much for the help. I'm amazed at your high availability and efficiency.

Just to make sure I don't spend more money for nothing, NUC8i3BEH should be good right? 

Thanks again for all the help, you're great!

[Craig Stout]

For the NUC8i3BEH - we added support for Iris® Plus Graphics 655 (0x3EA5) based on a 3rd party contribution, so I assume it works.  However a Kaby Lake NUC7 like the one Justin suggested would be a safer choice.

[Ron Even]

One last thing, the processor itself doesn't matter right? If I take NUC7i5DNHE and not NUC7i3DNHE it should still be fine

Thanks

[Justin Mattson]

The processor* matters very much actually. This is because with these systems there is an integrated GPU, which is to say the CPU and GPU are on the same module. According to Intel, this has an i5-7300U, which has a HD Graphics 620, which according to wikichip a slightly higher clocked version of the same GPU in the i3-7100U, so it is compatible.

*By processor I'm taking the assumption that you mean the system-on-a-chip (SoC), which combines a number of different components into a single unit. In this case there is a Core i5-7300 CPU combined with an Intel HD Graphics 620 and a number of other things I'm not smart enough to know about.

Hey, sorry for the latency.

Do you have a recommendation of a machine that will surely work with Fuchsia and is probably available for purchase?

I couldn't find the models you suggested as they are quite outdated.

I don't mind too much about the price or the architecture (I need the machine especially and exclusively for Fuchsia)

I really appreciate your help! Thanks!

[Alex Legg]

It looks like there is some discussion here about changing the documentation: https://fuchsia-review.googlesource.com/c/fuchsia/+/534722

Copying what Justin commented here:

---

Looking at the device IDs files and the Intel specs it looks like we support the NUC7i[3|5|7][B|D]* models (https://ark.intel.com/content/www/us/en/ark/products/series/129706/intel-nuc-kit-with-7th-generation-intel-core-processors.html) and the the NUC8i[3|5|7][B|D]* models (https://ark.intel.com/content/www/us/en/ark/products/series/129705/intel-nuc-kit-with-8th-generation-intel-core-processors.html).

Crucially I think this is almost all of the "NUC Kit with 7th Generation Intel Core Processors" and most of the "NUC Kit with 8th Generation Intel Core Processors", but NOT "Intel NUC Kit with Intel Celeron Processors", which is what the poster on the list has.

---

Based on Intel's status field, the models listed there that are not "discontinued" are:

Intel® NUC Kit NUC7i5DNKE

Intel® NUC Kit NUC7i5DNHE

Intel® NUC Kit NUC7i3DNKE

Intel® NUC Kit NUC7i3DNHE

Intel® NUC Kit NUC8i5BEK

Intel® NUC Kit NUC8i5BEH

Intel® NUC Kit NUC8i3BEK

Intel® NUC Kit NUC8i3BEH

Intel® NUC Kit NUC7i7DNKE

Intel® NUC Kit NUC7i7DNHE

Intel® NUC Kit NUC8i5BEHS

Intel® NUC Kit NUC8i3BEHS

Justin, can you confirm that I've enumerated that correctly?

[Justin Mattson]

Yes, that's right. I think some or all of the 8i are covered under the contributed code that Craig mentioned.

[Ron Even]

Just wanted to let you know that I bought the NUC8i3BEHS and now it works

Thank you very much for all the help!
