Rpi3 support #418

diederikdehaas · 2016-08-08T21:42:19Z

There are still items to be improved, but it is essentially working on my systems.
One particular point that needs to be improved is the serial console/bluetooth. It is working during install, but during normal boot after the install it is not. And we probably need to add a config option which determines what to do with the UART port as that is either serial or bluetooth, but not both.

But for the time being people can now use the installer on a Pi 3 (but do have to build it themselves for now)

So I'd say this partially fixes issue #375

While DT was (too) new in kernel 3.18 it is working properly in kernel 4.4+, so re-enable DT for all Pi's.

Kernel and initramfs are the same as for the rpi2, but to enable the serial console, we need to specify 'enable_uart=1'.

The Hardware field of /proc/cpuinfo doesn't allow us to differentiate enough, while the Revision field does, so switch to that.

…rsions. While the new detection statements also detect other versions (cm, 0), let's deal with that when the need arises.

Looks good to me.

See debian-pi#415 (comment) for details.

Mausy5043 · 2016-08-09T12:47:58Z

Just tested it.

diederikdehaas · 2016-08-09T15:09:05Z

Also updated the README.md to include RPi 3B.

cherylquirion · 2016-08-12T23:33:29Z

Done. May I just say that I love your work. ;) It is working great for me guys. Well done. This build is absolutely smoking on the RPi3.

I will do another complete build of our system from scratch over the weekend just to confirm.

cherylquirion · 2016-08-16T16:15:36Z

Did a 2nd pass yesterday. All working well for me.

cherylquirion · 2016-08-25T22:14:15Z

Anyone having issues with installing RTC? We just got a new board and are trying to get rtc running to no avail.
[Updated] Never mind. User error. :)

aykevl · 2016-09-02T11:50:55Z

Works well for me, on my new RPi 3B. I built the installer and copied all files in bootfs to the root FAT32 partition on the SD card (manually partitioned with gparted at the 4MB erase block offset), as there is no official build yet.
The README needs some updates though, only in the beginning version 3B is mentioned, further down only 1 and 2.

Do you mean "enable_uart=1" here?

Indeed. Thanks for spotting this 👍

aristosv · 2016-09-28T16:12:28Z

Following the build guide I created a build of the latest raspbian-ua-netinst. I run these commands:

git clone https://github.com/debian-pi/raspbian-ua-netinst.git
./build.sh

Everything run without errors, and created the .zip file.

I put it on a microsd and into the rpi3. I only got the rainbow screen.
I put the same microsd on an rpi2 and it worked just fine.

What I'm I doing wrong here?

Mausy5043 · 2016-09-28T16:23:49Z

Try this:

git clone https://github.com/debian-pi/raspbian-ua-netinst.git
git checkout v1.1.x
./build.sh

aristosv · 2016-09-28T16:59:24Z

root@debian:~/project# git checkout v1.1.x

aristosv · 2016-09-28T17:00:01Z

oops, I had to go in the folder.

m1dnight · 2017-07-12T11:54:39Z

I have tried building the image from the branch v1.1.x and I get a kernel panic. I would give more information but it scrolls by so fast I can't show much.

Anyone else experiencing this?

CWempe · 2017-07-17T21:27:14Z

Yes, it is a known issue.
The workaround is to edit the config.txt.
#472

But I am not sure what the solution will be.
Will down-/upgrading the firmware or kernel solve this?

Mausy5043 · 2017-07-18T16:15:18Z

Please retry with the current v1.1.x branch (w/ #475 merged).

CWempe · 2017-07-19T13:59:11Z

I just tried a version I compiled yesterday.
raspbian-ua-netinst-20170718-gite45eac1.zip

Bu still get the kernel panic. :(

git log show this:

    Add HWRNG kernel module back and explicitly load the module. (#479)

    It was built-in with kernel 4.4, but with 4.9 it is once again built as
    a kernel module (like it was before 4.4).

    Merge pull request #475 from Mausy5043/kernel-4.9

    Change to Raspbian Kernel 4.9

So I think I am using the right branch/version.

Mausy5043 · 2017-07-19T15:14:20Z

@CWempe and with UART disabled it works (again)?

diederikdehaas · 2017-07-19T15:35:07Z

I (normally) do my initial install with a serial console, so I can see what happens, and the enable_uart=1 prevents the installation from even starting. Disabling that line made the installation start.
Problem is that I have no clue what's currently happening, but I suspect that the reboot will fail as that enables the uart again.

It is very likely that we need to switch to properly using the overlay mechanism and figure out how to do things 'the new way'.

diederikdehaas · 2017-07-19T15:46:24Z

I have these issues open in tabs as they deal with it, but haven't had time to properly go through them:

RPi-Distro/repo#31
RPi-Distro/repo#22
raspberrypi/firmware#553

They may also be dated as I opened those tabs a while ago, but probably worth taking a look

diederikdehaas · 2017-07-19T15:54:04Z

I suspect that the reboot will fail as that enables the uart again.

And indeed. Reboot failed. Disabling the enable_uart=1 and it booted up.

So my suggestion is to disable that line for now, create a new beta release so the new kernel can be tested more broadly which may also fix some issues, and create a new issue to tackle the uart/serial console problem so we can get it working again.

Mausy5043 · 2017-07-19T17:11:27Z

PR #480 should fix this.
I've added an option enable_uart which is 0 (disabled) by default.
