Re: [U-Boot] Any good __LOW COST__ MIPS SBC suggestion please

2010-03-09 Thread Damien Dusha

 It will be nice, if its an SBC, and it has atleast 64/128 MB SDRAM, and
 16/32 MB flash, USB support, (i can;t expect a super fast processor, but a
 decent one like 166/200 Mhz should be ok)


Pure speculation, mainly because I was thinking about getting one myself,
but perhaps the Netgear WNR3500L, which also has a specific Linux port.  The
specifications are available at [1] and it appears to meet your criteria.

Has anyone used one before?  If so, what was your experience?

 Hi Florian and Jerry,
 
 Thanks for the inputs, i was actually going through the choices, and yea 
 as suggested Lemote seems to be a nice choice for me, and was wanting to 
 see distributors in the US / US shipping options.,

Based on your .in email domain, I did not expect that to be a problem. :-/

 also i had a look at the Linksys routers that you guys mentioned, but 
 one question, aren't the commercial products different from those of 
 development versions?, 

There are no development versions.  That is why they are cheap. ;-)

 I mean, when i opened up my WRT 610N, i could see  that, the main
 section of my router board is sealed in a steel casing(guess heat
 dissipater), though i can get the specs online,

The metal enclosure would be a EMI shield.  This is typically needed 
over the RF sections, sometimes needed over the processor sections.  It 
may or may not cover interesting things (processor, JTAG connector, etc).

 but does it have JTAG ports for debugging support? usually in production 
 versions, the odm's doesn't provide JTAG right? well, i couldn't see one 
 though.

The JTAG port is typically pads with no connector installed.  The 
designer/developers need it for development and the manufacturer 
typically needs it for loading new boards or debugging bad boards.

Developers get boards with connectors installed (special builds or 
add-on).  Manufacturers will use a fixture with pogo pins to stab the 
pads directly.  You get the opportunity for showing creativity, 
ingenuity, and soldering prowess.

 Just curious, will we be able to get development boards of Linksys WRT 
 SKUs? 

No.  Linksys is in the business of selling lots of turnkey boxes, not 
development stations.  Their attitude varies between tolerance and 
unhappiness with respect to hackers repurposing their boxes.

If you are looking for development boards, the off-the-shelf 
repurposing that Florian and I have mentioned do not fit your desires. 
You will need to restart your search with actual eval/dev boards and 
probably pay more money.  The advantage is that you will probably get 
better help and more information from the (re)seller.  The disadvantage 
is that you will pay more and probably learn less.

 Thanks
 
 Balaji R

Best regards,
gvb

P.S. Florian: Thanks for the added info, that was very helpful.

 Two off-the-wall thoughts would be to use QEMU (the ultimate in low
 cost) or a MIPS-based wireless/firewall/router.  A fair number of the
 cheap ones use versions of the Realtek SoC processor, which is MIPS
 architecture:
http://www.linux-mips.org/wiki/Realtek_SOC

This is actually a really bad choice, unless you start using Realtek WiSoCs 
(RT30xx/RT28xx). RTL8186 and RTL8651B are using a Lexra core, which is famous 
for not having 4 patented instructions (lwl, lwr, swl and swr), which 
therefore requires a different toolchain. Also the Linux support is just non-
existent. Finally they use a brain-dead bootloader called ROME which only 
allows a couple of actions to be performed.

More seriously, buy a WRT160NL or WRT54GL from Linksys, which is equally cheap 
as those Realtek devices.

 
 As another possibility, you may be able to pick up a Lemote computer
 which uses the Loongson processor:
http://en.wikipedia.org/wiki/Loongson
http://en.wikipedia.org/wiki/Lemote

This is a much better choice :)
