I've been trying to work with this newest version. But I seem to get an error when I MSD_Initialize, returning an error code of 8.

I'm not using zds so I'm not using the U_call macro, does there seem to be anything wrong? MSD8x the app does get past initization and displays files. (preceding unsigned comment by Jim_e (talk • contribs) 12:48, 17 August 2006 (EST))

Error 8 is one of those not very helpful ones because it means something has gone wrong during initialization, but not any of the other error conditions I check for. My initial reaction is to say make sure the device was not previously initialized, the port was in a reset state (plug/unplug the cable and turn on/off the calculator), and that your batteries are fresh. It seems odd that it would work with MSD8x but not with your code, though. Maybe Brandon will have a better idea --Dan Englender 12:17, 17 August 2006 (PDT)
