Tim,

looks like that (&**"/!/! programmer does not work with 2560 MCUs  .

SparkFun suggested I tried to upload blink.ino with the adapter. Since that does not seem, possible in the Arduino's IDE, I tried from AtmelStudio with VisualMicro... I got that message for minutes:

Tim,

some more information.

SparkFun support person suggested I try to upload blink.ino to the board using the programmer. Her theory is that the TinyUSB may not have enough memory to upload the bootloader for the Meg Pro Mini. Well I succeed in uploading blink.ino. I then tried to upload my own program, about 24 K, but didn't succeed. I also ask her which programmer they use to burn the bootloader to these board, and was told it's the AVRISP mkII.

So I got an AVRISP mkII this afternoon. Plugged it in and the driver automatically installed. All is fine I thought... no so  . I tried to burn the bootloader with Arduino's IDE and I am told no USB device found (can't recall the exact message).

I had a looked in Device Manager and found out under Jungo AVRISP mkII. I rebooted the computer, same error message. As far as I understand, all the programmer would use the same driver, libusb.

Tomorrow I will try to upload my program from AtmelStudio withe the AVRISP mkII, hoping it's going to work.

To you best knowledge, is there anything that needs to be installed for that programmer to work in AtmelStudio ? I got a CD with tools for AtmelStudio up to V 5, so I didn't install anything.

One more question: when uploading a program with a programmer, is there a need for a specific bootloader in the MCU ?

Gee, I never thought it would that completed to use a programmer  .

Thanks

If I get you right:

(1) I should remove the jungo driver
(2) Remove any libusb driver installed for the USBTinyISP programmer
(3) Install the libusb for AVRISP mkII (there seems to be only one kind of libusb driver ?!?)

Then I should be able to burn the bootloader with either Arduino's IDE and AtmelStudio+VisualMicro ?

I fear that next time I plug in the mkII, the jungo driver will be installed automatically.

Thanks

Tim,

still a nightmare  . I haven't succeded in getting rid of jungo. I deleted the mkII under jungo, and when I reconnect the mkII, the driver reinstalls. I found out here http://avrstudio5.wordpress.com/2011/12/02/setting-up-the-avr-jungo-usb-driver-m... instructions on how to remove jungo with wdreg (they6 use their own installer .) I rebooted, connected the mkII and again the jungo re-installed. Since I am not able to get rid of it, I de-activated mkII under Jungo connectivity. No cure...

I tried burning the bootloader form the IDE after I removed mkII under jungo, and got:

I tried with the mkII unplugged, and got the same.

So since I found out the libusb drivers for mkII, I tried to install: all I got is a cmd window that promptly disappears as it would not work.

You seems to say that the libusb installer would prompt for the programmer type. Where did you get that installer ?

Thanks

From http://avrstudio5.wordpress.com/2011/12/02/setting-up-the-avr-jungo-usb-driver-m...

in a cmd prompt I typed "wdreg.exe –inf windrvr6.inf uninstall". Maybe it's not enough. How do you remove jungo ???

I read somewhere that in control pannel > Program and Features that there should be an entry7 called "AVR Jungo", haven't found it.

Tim,

some news.

Robert tested on a different computer. He cleaned it up from AtmelStudio, installed Arduino's IDE and the libusb driver for mkII.

Uploading blink.ino wqith the mkII worked fine... but trying to burn the bootloader, he got the "no usb found" message. Looks like the IDE does not address the programmer the same way when uploading a program and burning the bootloader.

No one is going to uninstall AtmelStudio and VisualMicro from my computer  .

About Jungo, when deleting it, the check box says "remove that driver" and permanently is not shown. But I have a French Windows, maybe some dropped the word when translating.

The message is:

usbdev_open(): did not find any USB device "usb".

We get the same message when we try with the USBTinyUSP, for which the libusb driver is also installed.

But the IDE finds it (mkII) when it uploads a program.

I was able to try to burn the bootloader with the USBTinyISP. But there is a difference: I run Arduino 1.0.5 and Robert runs 1.0.5 r2 (added support Windows 8 and 8.1... and a bug ?).

Not in Windows, but is it possible that in 1.0.5 r2, they introduced a bug ?

VisualMicro is not on Robert computer, because when AtmelStudio is installed, Jungo comes in.

I tried something on my computer. I plugged in the mkII, the /!/!"""% jungo driver installed, then I right-clicked it, and replaced by the lisbusb driver. Unplugged the mkII, plusg it again, it's now under lib-usb win32 devices  .

If I try to upload blink.ino in VisualStudio+VisualMicro, no error message but « Uploading to I/O board using 'avrispmkii' » till the ends of time.

AtmekStudio is not frozen, afterwards I ask to burn the bootloader and get:

System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at processing.app.debug.AvrdudeUploader.burnBootloader(Board boardPreferences, String programmerName)

I closed AtmelStudio, reloaded it and fisrt thing I asked to burn the bootloader: same message from .Net.

The I did another test, with IDE 1.0.5 and mkII:

• I was able to upload blink.ino
• Then I ask to burn the bootloader. No complain about the usb device... but got an error in verification:

This time right at first byte.

Looks like I went over my device driver/talking issues, but burning the bootloader fails for still unknown reasons  .

And looks like it proves my point about  abug in 1.0.5 r2 ?!?

The SparkFun Pro Micro 3.3 v. You told me previously that the board definition is not per Arduino standard. When I tried first to burn the bootloader, VisualMicro told that the board does support bottloader burning - or something like this.
