   Hi all,

   I'm running IDE v0.0.12 on OSX.

   I have a mini r3, but the board selection menu only has (among other Maple boards) mini r2 - I assume this will work fine for the r3?

   Plugging in my mini via USB, no device was detected. Resetting the mini, putting it in perpetual bootloader mode, resetting the IDE, and restarting my computer did nothing. No "serial port" was ever detected.

   I decided to reflash the default mini bootloader with the file from http://static.leaflabs.com/pub/leaflabs/maple-bootloader/maple_mini_boot.bin. This was successful; I got a “Verification OK.”

   Now when I plug in the mini, the LED doesn't light so I have no idea if it's in bootloader mode, and it still does nothing on the USB bus. Plugging it into a Windows XP machine does nothing too.

   Please help!

   Thanks,
   Scott

   Scott,
   Because the maple uses a dfu based boot loader, The serial port won't show up until you actually program the chip. (and then only when the os decides to enumerate it) To make matters worse the maple_mini_boot.bin provided does not seem to use the correct led pin. (this is a serious bear on windows where you have to load drivers for both the dfu and the cdc classes before anything works)

   On a mac you can verify that the board is detected in dfu mode by going to about this mac and selecting more info and then pressing the system profiler button (<=10.6) or system report button (lion) . Under hardware select usb and it will give you a list of what is attached. (note: this info will not be automatically updated and will need to be refreshed (⌘-R ) as you plug in or change the mode of the maple). On linux you would use lsusb to get the same information.

   When the maple is in dfu mode it will show up as "Maple 003" with a vendor id of "1eaf" and product id of "0003". When the maple-mini is running valid code then, after what seems like forever (about 750ms), it will show up as "Maple" with a product id of "0004" and on a mac there will be a /dev/tty.usbmodemXXXX where XXXX is usually tied to the port you plugged it into (though you can't rely on this) and on linux you should see a /dev/ttyACMx.

   Initially it won't emulate a serial port and should stay in a perpetual boot loader mode until a program is uploaded. The board selection of Maple Mini r2 should work fine for the r3 as there was minimal changes. It could be a CDC ACM device when in perpetual boot loader mode I believe for Linux and Mac OSX. Did Windows XP ask for any drivers when you plugged it into that machine?

   Hi All,

   Thanks for the responses. Sorry for my delay getting back to you.

   Plugging in the mini to my MacBook Pro shows no activity on USB. No device is registered.

   XP asked for no drivers.

   Not sure if this help, but I'm reading 5V at the USB Vcc connection, 4.7V on the Vin pin, and 3.3V on the Vcc pin.
