Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

I'm one of the guys from the "task force", and also the person who replied to the issue you just opened. The reason I haven't posted in the Raspberry Pi forums about that effort is that, as this stage, we don't really have much to show for (you're certainly not going to be able to install vanilla De...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

Does anything come up on the HDMI output? Does anything come up on the serial port? On both outputs (since I have GRUB configured to output to serial as well as EFI console. Note that you'll need yet to be released UEFI Firmware v1.6 for that to work), here's what I get after selecting Debian GNU/L...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

I would suggest running `blkdiscard /dev/<sdcard device>`. That's fine, and probably a good suggestion if you are on Linux... but the guide is meant to cater to Windows users as well. Also, from what I can read, there aren't many SD card readers that support TRIM and apparently the one well known h...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

...and of course, the minute I posted the above, I remembered that, if I'm not mistaken, start.elf is for the VideoCore so it's not really something that we will be able to combine. But what I mentioned about decompressing each stage still stands, and even with a standalone start.elf , and early boo...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

The .dtb is included in the UEFI firmware so there's no need to provide it separately. And my current understanding is that start.elf probably duplicates a lot of things that the firmware does and, ideally , we should be able to combine them into a single EEPROM binary that merges the two, but which...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

Okay. I still appreciate your willingness to engage in this kind of discussions. 8-) Hopefully, there will come a stage in the future of the Pi platform, even if it's long term, where the benefits will be seen as outweighing the cost increases. For the time being, I guess it'll up to the people invo...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

I appreciate the reply, but can you give a an estimate for how prohibitive the cost of going from a 4MBit to a 16MBit EEPROM would be for a Pi4? The thing is, we're not even asking for a redesign here (since it's SPI), just going from an existing 512KB EEPROM to a model with 4x the capacity (since, ...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

won't the OS also scale / throttle the cpu speed as needed? Yes. The custom frequency you set is the maximum frequency you want, but as with all modern CPUs, the OS kernel will scale / throttle down that frequency when the load is low. is it possible the loader would support other versions of the p...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

On a RPi3B , the installation was successful, thanks to the details, ( https://pete.akeo.ie/2019/07/installing-debian-arm64-on-raspberry-pi.html ) Great! So how can one install the latest WoA-1903 using this UEFI ? This is outside of the scope of this thread, which is for Debian, but you'll find a ...

Re: Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

the guide was relatively easy to follow and everything went pretty smoothly apart from a few issues. Thanks for testing it and reporting! letting the installer automatically allocate partitions based on free space is bad because it will complain it can't find the Uefi parition then later grub will ...

Guide: Installation of *VANILLA* Debian 10.0 or later on Pi 3B/3B+

This guide describes the installation of vanilla Debian 10.0 (or later) using the official ARM64 ISO, on a Raspberry Model 3B or 3B+. Vanilla here means that we are going to be installing straight from an untouched ARM64 Debian netinst ISO , with no need for custom kernel modifications or any gymnas...

Re: uEFI grub2 on Raspberry Pi, Alexander Graf from Opensuse

This is about 2 years late, but you might be interested to know that we now have a full UEFI firmware for the Raspberry Pi 3, that is part of the official EDK2 implementation. Details of this firmware can be found at https://github.com/tianocore/edk2-platforms/tree/master/Platform/RaspberryPi/RPi3 a...
