FreeBSD 10 Builds

I'm excited to see a NOOBS version of the new FreeBSD 10 build. It's a very stable and mainstream operating system that can really enhance the Raspberry Pi, just as long as the appropriate WiFi and BlueTooth drivers are also included.

Thanks in advance!!

Re: Set video memory to 0?

I wanted to do this, too, but 16 megabytes is the lowest setting possible. Ponderous, I know, but that's the lower limit even if you do not intend to do any graphics at all.

But don't most Raspberry Pi boards that were shipped do not have this bug?

Re: New Overclocking bricked my RasPi

It's definitely not bricked, and I'm overclocking mine on Debian Wheezy with no complains, for that matter.

Re: Minimizing SD I/O

Pretty much mount /var into a ramdisk in order to keep flash memory writes to a minimum. Of course you lose diagnostic data but that's how we did it when we implemented a flash-based filesystem on Linux in the olden days. Some subsystems write to /etc but I forget which they were and even then they ...

Re: How to reduce memory for graphics lower than 16 megabyte

Oh, in the literature it states that the VideoCore is a CPU+GPU and can be used as a full computer without an extra CPU. I didn't realize that the Pi has both the ARM CPU and the VideoCore coprocessor used together in the traditional configuration which led me to believe I could allocate less memory...

Re: Power Supply will it work?

I have found that the length and quality of the cable matters if you expect to plug anything into the USB ports of the Raspberry Pi. I have lots of cables but the only ones that work reliably are of the three-foot variety. I don't really know why, but when I use cables that are longer than three fee...

Re: How to reduce memory for graphics lower than 16 megabyte

Oh, thanks for that info. Thanks to you folks and after reading the literature on the VideoCore it finally occurred to me that the Pi is using the VideoCore as the CPU as well as the GPU which is unlike most other applications which are just using it for video. That makes perfect sense to me now. Th...

Re: How to reduce memory for graphics lower than 16 megabyte

Okay, thanks. I was wondering if that blob can be configured to use even less memory than 16 megabytes for the framebuffer.

Re: Minimizing SD I/O

In your lifetime you're not likely to wear out the SD card if it was made after 2005. The most effective thing to do is to arrange to mount /var into a ramdisk. That's fairly easy to do in BSD Unix and Red Hat Linux but in Debian and Ubuntu it is not so easy since they depend so heavily on persisten...

Okay, but why can't I do that?
Is this a limitation of the hardware or do we just not know how to do it?

How to reduce memory for graphics lower than 16 megabytes?

How can I reduce the memory used for the VideoCore graphics to a value lower than 16 megabytes? It looks like it's a hard-coded kernel change since the setup script just links to the version with the memory allocations baked into it. I want to allocate a little memory as possible to memory, like 2 o...
