I've got a couple of projects that use uSD, both ARM and dsPIC and never needed power cycling. I'm using someone else's libraries for the SD card though. FWIW, I only read the card after power-up and don't hot-swap them so that might be a big factor. http://members.cox.net/ebrombaugh1/synth/armfpga/index.html http://members.cox.net/ebrombaugh1/synth/dsPIC_fpga/index.html Eric _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
