Popular MIPS4Kc boards?

Popular MIPS4Kc boards?

[Krishna B S]

Hi All,

I have to develop toolchains for various MIPS boards my company
develops. All the boards consist of MIPS 4KC.

I would like to know from you what is the most popular board used by
the community with this kind of processor. I know, its tough to get a
clear answer.

But, my intention is to first port my toolchain/kernel for this
popular board so that I can get your support, in case I encounter any
problems. Having confirmed the working of the toolchain for this
board, I would port it to my company's boards.

(The popular board in the community would be my reference board for
development.)

Kindly give your valuable comments.

Regards,
Krishna

 You could use one of the consumer devices as a development board ;)

I.e. : http://www.linux-mips.org/wiki/Adm5120 or
http://www.linux-mips.org/wiki/Broadcom_SOCs

 This devices costs about $50..100 and includes case, power supply,
Ethernet, RS-232, Flash, DRAM (16 to 32Mb), USB an one or two
MiniPCI slots.

 You could use a USB stick or IDE HDD with USB-to-IDE controller 
to mount a root partition.

 There are a lot of MiniPCI peripherial cards: WiFi, sound, IDE,
Serial ATA and seems even SVGA.

You can probably download toolchain from
http://www.linux-mips.org/wiki/Toolchains and try them first.
Later you can try compiling toolchain from buidroot.

The price tag is juicy but for serious development with a 4Kc I'd
recommend a MIPS Malta.  Forcing consumer hardware into submission may
be a fun project for a spare time hacker but in general isn't a very
productive process for somebody who needs to finish a job soon or needs
to additional hardware such as PCI cards, logic analyzer, additional
memory, other CPU types etc.

And if we talk about fan project, are there any MIPS64 based devices on market?

The Playstation comes to mind.  It however isn't MIPS64 but 64-bit MIPS ...

Nah, the PlayStation has an R3000 :-)
I guess you meant the PlayStation 2...

Another 64bit MIPS CPU based device is Tivo series 2.  So I heard.

A possibility for a MIPS64 based device might be the recently announced
Broadcom BCM97398 IPTV set-top box reference design platform:

    http://tinyurl.com/bm44b

This contains a BCM7038 with a 300 MHz R5Kf together with enough
peripherals to make it interesting: 2 x UART; 2 x SATA; 2 x USB 2.0;
10/100 Ethernet.  If produced in quantity and available it would
probably be more affordable than low volume evaluation boards.

What I would like to see is a multicore (multithreading?) MIPS64 chip
attached by HyperTransport to a PC chipset (eg. Via KN800A) on a small
form factor board (mini-itx; micro-atx; micro-btx).  An ideal plaything
for the kernel hacker and a useful resource for academic teaching and
research - a modern version of the UNSW U4600 ...

There's a wild difference between the 5Kf, a relativly simple 64-bit core
and one of the current 32-bit & 64-bit multithreading cores coming out.
For the latter ones you'll probably still have to hold the breath for little.
