Re: [U-Boot] Any good __LOW COST__ MIPS SBC suggestion please
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? -- Damien [1] http://www.myopenrouter.com/article/13378/Features-and-Specifications-NETGEAR-WNR3500L-Open-Source-Wireless-N-Gigabit-Router/ ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Hi Balaji, Please don't top quote. Balaji Ravindran wrote: 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.
