Re: Mainline Kernel building -- problems and issues

What do you expect from linux-next in comparison from much stable stuff like linux-5.7.x or at least linux-5.8rc2? Do you have your screen connected via HDMI? Did you copied the kernel modules to the SD card? I expect to be able to test the linux-next. Nothing else. Yes, I have HDMI. Okay, it seems...

Re: Mainline Kernel building -- problems and issues

I haven't got linux-next (the unreleased mainline kernel) working yet. It doesn't get past the initial colorful screen on the boot. I have a 32-bit Raspbian install on my RPi4 and I try get the linux-next kernel running on it. I have done compiling on RPi3 (because I'm busy using my RPi4). Here is w...

These overlays are not supported by the mainline kernel.
So, no overlays are needed at all to get Raspbian running?

Re: Mainline Kernel building -- problems and issues

I tried to use the tutorial of the first post on this thread for building a 32-bit linux-next for RPi4 but without cross-compiling (so I partly used the standard instructions to get through without any cross-compiling). I didn't have success, it gets stuck on the initial color screen. I'm trying to ...

Re: RPI3B+ I would like to make a game

Initializing and reading from the SD card is quite a complicated task. I'd suggest using a bare metal library first (like Circle) and looking how things are done, then you can decide to go the full assembly way or stay quite close to the metal but with a library. Even if I want just to draw some pr...

Re: Kernel downgrading with apt-get? (Raspbian)

What version is in the book? It is likely that the interfaces haven't changed significantly so your current kernel is fine. 4.9. and I currently have 4.19 installed. If it has changed then you should learn the new method anyway. Well, my first step is to get something working and I'd like to be sur...

Kernel downgrading with apt-get? (Raspbian)

I try to downgrade my kernel to the version which my driver writing study book uses. Is it possible simply to get earlier kernel version running by installing its image and header package with apt-get? I found the right LTS-kernel version from repositories but merely installing the kernel image & he...

Re: Pi 4, Raspbian Buster and Wine 4.0

So how handy that solution (Novaspirit's for running win32 programs, using RPI4) actually is? Can I use it as a part of my otherwise normal operating system smoothly if I want to use just one or two Windows programs? Or would it rather need an SD card of its own?

Raspberry Pi 4 as a primary desktop computer?

I wonder how it would be like to use Raspberry Pi 4 (with 4 GB ram) as a primary desktop computer at home. RPI4 seems to have enough CPU power and ram to run YouTube and rest of the typical websurfing smoothly, I presume (smoothly at least for a person like me who have uses a 13 year old desktop com...

Raspberry driver writing practice project

I'm trying to conceive me a Linux driver writing project. I could make it either on an ordinary x86 laptop or on a Raspberry Pi 3. Now I've been thinking if Raspberry has devices which would suit particularly well for this purpose. Because this is a practice project the device can already be support...
