Re: New Pi 4B v1.2?

@laurent, Official announcements are great for traceability of your products life cycle. In my company, we use many Raspberry Pis on internal products. I think if you want an SBC with a rigorous and unchanging specification and/or months and years of advance warning of changes an/or long term suppl...

Re: Future of raspberry pi - software related

I'm surprised that no one mentioned mainline Linux support for our favourite SBC. It has been mentioned many times that they are hardly working on it on Pi tower, but it would be a great achievement for the future. For my point of view, the biggest software improvement on the Pi 4 is the Anholt/Igal...

Re: How to Differentiate RPI4 - 1 vs. 2 vs. 4 GB ?

I remember also to stick a label with the MPEG2 licence numbers directly on early Pi models when I bought those licences in the past. You only need to load the key once. It permanently sets an OTP bit to indicate that you've paid for a license. Thanks for this information. I required this only for ...

Re: Disable 10ms interrupt on core 2&3

Hi, A Pi was never intended to do hard real-time tasks. This is a major difference between microcontrollers (particularly os-less ones) and any SBC running a conventional Linux. Those last ARE computers (hence their name). They are able to manage huge CPU and memory hungry tasks and services, which ...

Re: How to run Freespace 2 Open on Raspberry PI 3

Many thanks for your tests with the Pi 4, under Raspbian Buster. Unfortunately, the Pi 4 is unlikely to support more than OpenGL 2.1 :cry: At least, according to, what Igalia said: At present, the V3D driver exposes OpenGL ES 3.0 and OpenGL 2.1. As I mentioned above, the VideoCore VI GPU can do Open...

This revision may been planned before the USB-C "issue" discovery, and address some/many other minor points that doesn't need any staff explanations. If this revision really exists, and doesn't correct the USB-C "issue", a further one will do.

Hello, 3D acceleration with OpenGL ES through the legacy proprietary driver is no more supported on the Raspberry Pi 4. In order to enable the 3D acceleration, the v3d driver is mandatory. This is why it's enabled by default in the config.txt. I also managed to compile Qt with eglfs acceleration in ...

You don't need USB to Ethernet adapter to link a Pi Zero to any host, since the Pi Zero's USB port is OTG and can be properly configured in order to become an USB device port and act itself as a USB to Ethernet (Ethernet gadget). The Pi Zero don't even need a micro SD card, and can boot from a host,...

Re: Raspbian refuses to use Swap Space

Hi,
Its likely to be a maximum memory per process limitation. Even with many gigabytes of swap, you can't allocate more than a limited amount of RAM per process. But even with a 32 bit OS, it must be 4GB so I can't explain why you are limited to 1GB or so.
