Error while compiling

Hardware Portenta Portenta H7
1

I just got my hands on the Arduino Portenta and I selected that board under Tools>>Board and selected the right port. I also have the latest Arduino IDE software. When I plug in the portenta, the green and blue LED start blinking. But when I try to upload a simple Blink sketch, the portenta appears to go into bootloader mode (the green led starts flashing) and I get the following error:

dfu-util 0.9

Cannot open DFU device 2341:035b
No DFU capable USB device available
An error occurred while uploading the sketch

How can I resolve this? :o

There is an Arduino Portenta section of the forum.

You may get help quicker if you have a moderator move your post to that section. Make the request using the Report to moderator button below each post.

Do not make another post in that section. That is cross posting and cross posting is against the rules.
