8GB Version?

It's a bit odd, IF any RasPi needs 8GB, then one that's specifically designed to be a desktop system, rather than one designed for various embedded projects. So, the 400 not being available in an 8GB version is, well, astounding. Is that coming anytime soon? Also, in that keyboard would be the perfe...

Re: experimental support for multiarch with Raspbian and Debian arm64

So we have this effort here, and then we have this https://www.raspberrypi.org/forums/viewtopic.php?f=117&t=275370 which has the issue of no 64-bit Mathematica, etc. Why didn't these efforts just get merged? Wouldn't it be much simpler to just do a multi-arch distro, with some commands to thin i...

Re: USB-MSD boot EEPROM update - 2020-06-12

So the good news is, I got Kali to run on an RPi4B-8GB off the sd card moved from the sd slot into an USB-SD-card-reader, good enough as proof of concept. The way I got that done is by doing the rpi-update on a RaspberryPiOS boot SD card, and then copying /boot/start*.elm and /boot/fixup*.dat from t...

Re: RPI 4 8GB hardware version 1.4

Ah yes, so this thread already contains all the information needed. I wonder if we should have a page in the docs describing what needs to be done to port an OS. That would certainly not hurt, especially when revisions affect the boot process, because that‘s the most critical thing. Once a system i...

Re: RPI 4 8GB hardware version 1.4

A few images that worked with RPI4 4GB give me this error message start4x.elf not compatible. You may need newer firmware. That’s about the error I got with the most recent Kali image (2020.2a) Basically, what I’m missing is a documentation that would tell someone doing an independent distro what t...

why isn't USB-C networking enabled by default?

So far so good. Just one question: why isn't USB-C networking enabled by default? It seems to be an inordinate amount of stuff that's potentially fragile that needs to be done. I don't see what the harm is of that being enabled and unused. Not much different than my Ethernet port being almost always...

Re: RPI 4 8GB hardware version 1.4

Why would that affect the booting of the kernel?
Even after firmware update, the kernel gets stuck.

Also, and more importantly, where’s the documentation? If I want some OS distribution to adapt, I need to be able to point them at some documentation...

Re: RPI 4 8GB hardware version 1.4

Is there anywhere a detailed description of what exactly Rev. 1.4 changes? After all, the changes are deep enough, that a Kali Linux image, which boots RPi 3, RPi3+ and RPi4-4GB just fine won't boot on the Rev. 1.4 8GB board. I wouldn't even know where to start, without any detailed description of h...

Re: Kali Linux 2020.2a doesn't run on Raspberry pi 4 model b 8gb ram

Same problem here! Thing is, I can’t even find anything here on what the differences are between the 8Gb and 4Gb version, so how is anyone supposed to be able to adapt the OS? For all intents and purposes, bumping the RAM from 4 to 8 GB should not lead to an incompatibility, so there must be other c...

Also, since I’m already on the latest kernel, is there a way to force the update to run again?

Code: Select all

sudo rm /boot/.firmware_revision
Then run rpi-update again.
Thanks! That did it!

Re: Moving Linux Kernel to 5.4

How big are the new boot partitions? /boot is 256MB on the Buster images. Thanks! Great, that (almost) worked. Gparted refused to make a 256MB partition and “corrected” my input always back to 255MB, which should be big enough for the foreseeable future given that just about 22% of /boot are used n...

Re: Moving Linux Kernel to 5.4

I got two machines a 3B and 3B+, both of which should be 64-bit capable, but as can be seen here, rpi-update doesn't download the necessary files: Is this an old Stretch install you upgraded to Buster? rpi-update won't automatically copy the kernel7l.img and kernel8.img kernels if this was an old S...

Here's the situation: I connect to the RaspberryPi Desktop (running Raspian) from a Mac via VNC.

I could be tempted to just get rid of Firefox and stick to Firefox-ESR, but that still will not solve the Thunderbird issue. So, since the last post here was a while ago, is...
