"What happen????. somebody set up us the bomb!!!" :-?
and once of a sudden it works. same sticks, same computer (mac MDD os x 10.4.9) and disk utilities. first select whole drive and erase as mac os extended, not journaled. then format again as MS_DOS filesystem. eject and voila, working sicks.
How do i know?
make a working serial connection:
remove the atmega from your arduino. pry it off with a small flatscrewdriver. working your way in from both sides. connect the following signals:
orange to 0 RX.
yelow to 1 TX
red to 5v
black to GND
green to GND
notice that for normal arduino operation, orange goes to 1 TX and yellow to 0 RX
set your terminal program to the right port (in zterm hold the shift after staring up the app and select usbserial-xxxxxx where xxxxx is a unique serialstring)
connection speed: 9600, no handshake, 8n1
if you have a working serial connection between the VMUSIC and your computer watch for the right sequence:Device Detected P2
after removing notice the line that says:No Disk
if the stick is not recognized you'll get the shorter version:Device Detected P2
and nothing more. after removing only:Device Removed P2
so the best thing to do when starting with the VMUSIC2 is:
1. check the usb stick like mentioned above.
2. upgrade the firmware to the latest from:http://www.vinculum.com/downloads/firmware/ftrfb_main_03_64VMSC1F.ftd
notice that after pressing enter you also get the D:\> prompt. this does not indicate a working stick
if you send the string idd
the VMUSIC answers with something like:USB VID = $0204
USB PID = $6025
Vendor Id = USB
Product Id = FLASH DISK
Revision Level = 5.00
I/F = SCSI
Bytes/Sector = $0200
Bytes/Cluster = $001000
Capacity = $391AB000 Bytes
Free Space = $ Bytes
with a non working stick, you will have a empty line where it reads FAT32 and the sizes will all be zeros
