[Discuss-gnuradio] Re: SanDisk cards flakey?
Or maybe I have to try to use another brand SD card rather than Sandisk? It's possible you need to use another brand card, as these seem to be notoriously flaky. SanDisk SD cards are not notoriously flaky. They invented the SD Card format and are, I believe, the largest maker of Flash devices in the world. They're the gold standard for SD cards (and their Extreme line is the gold standard for endurance, surviving in cameras destroyed by flying debris, dropped from balloons at tens of thousands of feet, etc). If the USRP2 is notoriously flaky with SanDisk SD cards, there's almost certainly something wrong with the USRP2's implementation of the SD card interface -- not with SanDisk cards.

You're of course correct--I had missed the SanDisk brand name and my these was referring to SD cards in general I've used with the USRP2. No intent to malign SanDisk. It's possible there is a design issue with the SD interface on the USRP2. I'd consider it pretty unlikely, but not out of the question.

John ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio I will make an observation that this isn't the only forum where inconsistency in compatibility and performance with SD and SDHC cards has become an issue. The Plug Computer folks (Sheeva Plug, etc) are also running into problems with this card worked, that one didn't type problems.
