How to install on B+? about raspberrypipkg HOT 18 CLOSED

Try the May13th, in case you has stale bits for some reason...

MD5 (RPI_EFI.fd) = 0923fda247b8e3aea9db7d2ce9995611
MD5 (bootcode.bin) = 17efaf1c1ef89289168d71cdc8194982

@falkor2k15 if you have issues please also see #14. The May 13th builds got updated with a display driver fix (and there's documented quirks for HDMI now in readme.md)

from raspberrypipkg.

I just get a black screen, though the rainbow screen appeared briefly once before the black screen. I tried the May 13th builds (both woa-17125 only + normal). I also tried the following inside the config.txt:
arm_control=0x200
enable_uart=1
armstub=RPI_EFI.fd
disable_commandline_tags=1

AND

arm_control=0x200
enable_uart=1
armstub=RPI_EFI.fd
disable_commandline_tags=1
hdmi_force_hotplug=1
hdmi_group=1
hdmi_mode=4

Am I doing something wrong?

Are we meant to hit certain keys on the keyboard after powering on the RPi3B+?

from raspberrypipkg.

I tried all these files and now I'm just stuck on the rainbow screen instead of a black screen:

More files/folders needed than that?

from raspberrypipkg.

Definitely don’t add more files (just bootcode, start, and fixup).

Just to be sure, can you give me the md5 of the files you have?

Can you try the zip file linked in issue 14?

Do you have a Pi 3 (not B+)?

from raspberrypipkg.

OK, that one seems to work!

It comes up with a white-yellow UEFI shell screen - but how to get the proper GUI?

Yep, I have a newish B+, and can run Noobs, Raspbian, Ubuntu Mate, Gentoo, etc.

from raspberrypipkg.

OK great - I got it to come up by pressing ESC of course! So what is up with the May 13 FD files? Will you be able to fix this in future releases, or the B+ will need it's own separate release?

from raspberrypipkg.

Wow, I got Ubuntu 18.04 to boot up - nice!!! Unfortunately, it's not detecting the NIC.

from raspberrypipkg.

OpenSUSE works quite well and has KVM enabled. I tried several weeks to get that to work on the Pi, but could never do it - UEFI certainly helps! And it detects the LAN. I just cannot figure out how to get LAN or Wifi to work on Ubuntu 18.04, so it cannot be installed from the mini.iso.

from raspberrypipkg.

I’ve updated the May 13th bits last night, those should work...

from raspberrypipkg.

I didn’t try Ubuntu yet on the Pi3B+

from raspberrypipkg.

Great to hear SUSE works well!!!

I think I just need a step by step guide on how to inject the DTB file:
http://ports.ubuntu.com/ubuntu-ports/dists/bionic/main/installer-arm64/current/images/device-tree/bcm2837-rpi-3-b.dtb
I don't quite know what you do with this? But that will probably solve the Wifi issue? I know the B+ needs special LAN drivers that the normal Pi3 doesn't need (they both have different NIC models).

from raspberrypipkg.

For WiFi there’s more pain...see the hoops I went through with ubuntu on the Pi 3.

To use your own dtb involves a few changes to your config.txt:

...
disable_commandline_tags=2
device_tree_address=0x8000
device_tree_end=0x10000
device_tree=my_fdt.dtb

Note: the address range must be [0x8000:0x10000). dtoverlay and dtparam parameters are also supported.

from raspberrypipkg.

Yeah, I read that, but I don't understand. For example:

1. What is a DTB? Presumably it's a drivers file?
2. Does the DTB sit at the root of the boot partition or does it need to be installed via the operating system that we are attempting to install?
3. Do we rename it my_fdt.dtb or stick with the default DTB name?
4. How do we find out the address range? Or are we always sticking specifically with 0x8000:0x10000?

from raspberrypipkg.

DTB (device tree blob) aka FDT (flattened device tree) is a binary representation of system hardware, firmware hand-off state and configuration parameters. It is not a driver, but it is what lets a kernel know what drivers to load for what hardware.

In your case simply download http://ports.ubuntu.com/ubuntu-ports/dists/bionic/main/installer-arm64/current/images/device-tree/bcm2837-rpi-3-b.dtb into the same directory as config.txt. You can name it anything you want (as you will plug the name in config.txt).

The adress range must be the one I document. That area of memory will be scanned by UEFI for your DTB. If no valid DTB is found, an internal one will be used. Regardless, the DTB is used as a template and is patched to ensure correct configuration is passed to OS.

from raspberrypipkg.

OK I will try.... "The adress range must be the one I document." - you mean just in the config.txt file or specified elsewhere too? Do you think that will give me LAN access then at least? Otherwise I don't think can install as Ubuntu is part web install. Will give it a try nevertheless....

from raspberrypipkg.

I am saying 0x8000:0x10000 must be the numbers used in config.txt. You may not use different numbers.

LAN is enumerated by USB. A different dtb is not going to help - Ubuntu must just not have the USB nic driver. You could try a third party USB nic dongle, that could work ( like a simple USB2<->100Mbit one ). In fact the installer probably has less drivers than the installed system, so once you install, you may get working networking, who knows... I'll play with my Pi 3 and Pi 3B+ and find out eventually..
