[OpenWrt-Devel] Buying router SOC CPUs
Are any of the router SOC CPUs easily available for purchase? We've tried to buy some buy nobody wants to talk to us. As a work around we are using a lpc3130 ($3.50) and an OEM USB wifi stick ($4.00 ralink). We have to go through FCC anyway because of the 2.4Ghz 802.15.4 radio. -- Jon Smirl jonsm...@gmail.com ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

This unfortunately a common attitude from parts vendors, especially when you are not buying in qty 10k+. You might try asking vendors for a tray of samples for testing purposes, e.g. a dozen chips.

We are in the 2-4K volume range which is too low for them to apparently care about. If they'd just put the chips into a distributor and give us an accurate manual we'd probably never call the chip manufacturer. What is pricing like for the SOC chips? Would it be less that our $8.00 combo of lpc3130/USB wifi? USB wifi is flexible in that we can put in 11g, 11b, 5Ghz, etc sticks. lpc3130 is a very good chip for this since it has the integrated 480Mb USB PHY. > You might try asking vendors for a tray of samples for testing purposes, > e.g. a dozen chips. > > > On Tue, Jan 17, 2012 at 7:16 PM, jonsm...@gmail.com > wrote: >> >> Are any of the router SOC CPUs easily available for purchase?

Re: [OpenWrt-Devel] Buying router SOC CPUs
Many moons ago I was working with a startup developing a small battery-powered device based around TI's DaVinci DM355 SoC. http://www.ti.com/product/tms320dm355 We tried to use the MMC/SDIO interface to talk to an SD form-factor 802.11 card (since the USB was already assigned elsewhere), but I could see that USB working well for a cheap Ra-Link card instead. As to your question about pricing reference, the DM355 runs roughly US$20/ea from AVNet, for example. http://avnetexpress.avnet.com/store/em/EMController/Processor/Multimedia-Misc/_/N-100230/Ne-10?action=products&advAction=&cat=1&catalogId=500201&cutTape=&inStock=&langId=-1&myCatalog=&npi=&proto=®ionalStock=&rohs=&searchType=&storeId=500201&term=dm355&topSellers= We were able to get a tray of sample DM355's from AVnet, and it looks like they sell some of the pkg variants in qty 1.

Re: [OpenWrt-Devel] Buying router SOC CPUs
The SD form-factor 802.11 card we were trying to integrate was based on ath5k, IIFC, which would support AP mode. I believe we got far enough to test in STA mode (i.e.. test the wifi link to a conventional base station). Although, SD format factor for peripherals is not ideal, and possibly obsolete by now. The thread author would need to check whether the ralink driver supports AP mode (which doesn't look hopeful from Googling).

We hadn't tried AP mode. The device only has wifi and 802.15.4. The wifi is in STA mode. There's no place for AP to send traffic. If we had access to router SOC chips we'd add an Ethernet port and support AP mode. We have built several gateways using off-the-shelf routers and then adding a 802.15.4 USB stick. But we can't add the display and other peripherals to an off-the-shelf router. I would need to investigate Ralink and AP mode. The Ralink devices are softmac so almost everything is implement in the Linux wifi core. The Linux core definitely supports AP mode so the question is if it can get to enough features of the Ralink device to enable AP mode. We're going to investigate 11s after we get the basic device working. > > > On Thu, Jan 19, 2012 at 3:09 PM, Mark Deneen wrote: >> >> AP mode? >> >> On Thu, Jan 19, 2012 at 2:42 PM, Ben West wrote: >> > Many moons ago I was working with a startup developing a small >> > battery-powered device based around TI's DaVinci DM355 SoC. >> > http://www.ti.com/product/tms320dm355 >> > >> > We tried to use the MMC/SDIO interface to talk to an SD form-factor >> > 802.11 >> > card (since the USB was already assigned elsewhere), but I could see >> > that >> > USB working well for a cheap Ra-Link card instead. >> > >> > As to your question about pricing reference, the DM355 runs roughly >> > US$20/ea >> > from AVNet, for example. >> > >> > http://avnetexpress.avnet.com/store/em/EMController/Processor/Multimedia-Misc/_/N-100230/Ne-10?action=products&advAction=&cat=1&catalogId=500201&cutTape=&inStock=&langId=-1&myCatalog=&npi=&proto=®ionalStock=&rohs=&searchType=&storeId=500201&term=dm355&topSellers= >> > >> > We were able to get a tray of sample DM355's from AVnet, and it looks >> > like >> > they sell some of the pkg variants in qty 1. >> > >> > > -- > Ben West > http://gowasabi.net > b...@gowasabi.net > > > ___ > openwrt-devel mailing list > openwrt-devel@lists.openwrt.org > https://lists.openwrt.org/mailman/listinfo/openwrt-devel > -- Jon Smirl jonsm...@gmail.com ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Do you know if any of the router chips have a decent I2S implementation? RT3050 I2S is only 16b (not 24b inside 32b) and the internal clock can only do 48Khz. Realtek does not have I2S support. I'm looking for one that can do 32b I2S frames with 24b data (all recent I2S does this).

There are lots of ways we can add it, but the cost of adding it ruins the cost advantage of the using the router chip. Broadcom BCM4717 has i2s, but that's another vendor that won't talk to us.

Re: [OpenWrt-Devel] Buying router SOC CPUs
Yes, Indeed Broadcom is difficult to work with. So is Atheros since they were bought out by Qualcom. You should mention your goal price and how many units you want to manufacture and that can help me figure out what hardware you should use. You could always use a general SOC from a chinese vendor and use a usb wifi module since those cost about 10 rmb. Ingenic is pretty open and provides their software and schematics online without a NDA. For me I will use any SDRAM module that is compatible. Normally ISSI or Etrontech. I would like to source 64MB Modules too, but that is more tricky since they build less of that and its more expensive. Maybe I can buy them second hand and build a memtest86 machine to test second hand memory modules for 64MB Ram. I also have the Idea of building programming jigs for the routers. My theory is to cut down the time it takes to use the iqflex. On the USB based routers It can take over a minute to fully boot. The iqflex process can take less than a minute. So my idea is to use flashrom with ftdi 2232 to program a special quick booting image for the iqflex calibration. Put the router back into the jig, extract the calibration info. Use a barcode reader to read a barcode that contains the mac and serial number. Then generate a new image with the unique mac and calibration info. Then spi flash that unique image back to the router.
