There would be 2 options, move your development to the trunk version of openwrt of backport the 2 patches to the 8.09 release. I have included links to the 2 patches. https://dev.openwrt.org/browser/packages/net/gpsd/patches/101-trimble.patch https://dev.openwrt.org/browser/trunk/target/linux/ixp4xx/patches-2.6.28/191 -cambria_optional_uart.patch Thanks, - Chris -----Original Message----- From: avila-bounces at lists.gateworks.com [mailto:avila-bounces at lists.gateworks.com] On Behalf Of Tim Harvey Sent: Friday, February 27, 2009 8:41 AM To: avila at lists.gateworks.com Subject: [Avila] GPS access via gpsd Has anyone had issues with the GPS module using gpsd?? I'm currently using a GW2350 with on-board GPS module and it would appear that perhaps the Trimble module is using something other than 8N1 serial configuration as this is what gpsd uses (hard-coded) and looking at gpsd logs some of the messages from the gps have some duplicate characters indicative of serial misconfiguration.? I'm told that Trimble often uses 7E1 but I haven't been able to confirm this.? Before I go on a possible goose chase and start patching gpsd I was wondering if anyone else had seen some issues like this or had more info?? I'm using gpsd 2.37 and OpenWRT 8.09 (also tried gpsd 2.38 with the same results). Basically, the state of my GW2350+GPS is such that many of the messages from the GPS are tossed by gpsd and it takes many minutes to get a fix and often the fix is lost or I get funny data. I've used the 'GPS module' on a GW2348-4 in the past and don't recall these issues but perhaps I just didn't notice them back then.? It was also a different version of gpsd, and a completely different toolchain/build.? Are there any differences in the part used with the GPS module on the avila and the one on the Cambria?
