Hi,

I recently put together a custom board for a project that includes the RET6 chip. I successfully loaded the bootloader but I am getting an error once I try to upload code to the micro. That is what i get in the console of the IDE:

Searching for DFU device [1EAF:0003]...
Found it!

Opening USB Device 0x1eaf:0x0003...
Found Runtime: [0x1eaf:0x0003] devnum=0, cfg=0, intf=0, alt=1, name="UNDEFINED"

dfuIDLE, continuing

dfu_download error -104
Error during download

Any pointers to what might cause this?

Thanks!

I assume you're on a Windows machine? XP? 7?
Implement "BUT" and put the chip in permanent upload mode.
[as a noob myself I can't resist adding] Read the posting guidelines.
Report back with your IDE installation details.
Also check the documentation about how the USB deal works.
Its two devices to the computer which switch back and forth which Windows chokes on.

Thanks MediumKahuna,

I am actually on a OSX Lion. However, I reloaded the bootloader and it seems that the issue is fixed.

Thanks,
