Hello,

I got myself a pair of maple mini r3 and the regular maple r5. I setup the ide, and although i am able to upload the code into the maple r5 board, I was not able to upload code to the maple mini. I uploaded drivers, and when i run dfu-util.exe -l, I get:

dfu-util - (C) 2007-2008 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY

Found DFU: [0x1eaf:0x0003] devnum=1, cfg=0, intf=0, alt=0, name="DFU Program RAM

Found DFU: [0x1eaf:0x0003] devnum=1, cfg=0, intf=0, alt=1, name="DFU Program FLA
SH 0x08005000"

I got my board in perpetual bootloader mode, and then i tried to upload the blink program. When the board is in bootloader mode, I click upload and then i get:

Reset via USB Serial Failed! Did you select the serial right serial port?
Assuming the board is in perpetual bootloader mode and continuing to attempt dfu programming...

Resetting USB to switch back to runtime mode

However no matter what i tried i was not successful to upload code and execute it. And I wanted to ask, how do we get out of perpetual bootloader mode.

any ideas/recomendations/help greatly appreciated,

cambazz - Just to help us a bit more, what is the settings for Tools->Board when you're uploading from the IDE?

Have you tried changing the parameter to delay() in blink to ensure you are seeing the perpetual bootloader, and not the blink program? Try delay(100), which is a much faster blink.

Have you tried removing power from the mini, then applying power again? (That should take it out of perpetual bootloader mode) Does the mini show the program running?

Hello,

I choose maple Rev3+ to flash. And I closely observed the behaivor you suggested, and I determined it was unable to upload. However I then switched to linux.

Although Linux will not see the serial port, because the device disconnects after a little while, I then set it on perpetual bootloader mode, and programmed it as Mini Rev 2 to flash, and indeed, I am able to upload code, and run my own modified blink. It was also able to switch to run mode from bootloader mode, and I am even able to program without putting in perpetual bootloader mode, (which i accidentally discovered, by pressing reset when the board is trying to upload, and not being able to find and start searching for dfu, you just click reset - and it will find it)

So this device is marked as maple mini r3, but i have to choose mini rev 2 as board? I have confirmed this is the case.

Best regards,
-c.b.
