Trying to blink the GIGA board for the first time. The board is detected on /dev/ttyACM4 under Ubuntu 22.10 running IDE 2.0.5-nightly-20230303 with Mbed OS Giga library version 4.0.2.
Compile works but Upload fails with the following message:
Sketch uses 109408 bytes (5%) of program storage space. Maximum is 1966080 bytes.
Global variables use 47520 bytes (9%) of dynamic memory, leaving 476104 bytes for local variables. Maximum is 523624 bytes.

Haven't seen any instructions on flashing the firmware so I didn't try it not knowing what to do for this purpose. What is the basic way to get any sketch uploaded to the board? What steps have I (newbie) overlooked? Thanks.
Between Ubuntu and IDE 2.0, something is missing in udev configuration for a standard user to connect to /dev/ttyACM*. It is beyond my pay grade but sooner rather than later I hope to stumble across the recommended solution. Otherwise it is back to IDE 1.x where the standard user is a member of the dialout group.
Hello @PierpaoloP, the solution suggested by @jojo makes perfect sense for Linux platforms. There must be some equivalent operation for Windows too. We were indoctrinated by Arduino to ensure users are members of the dialout group. I wonder why the equivalent prerequisite is not categorically mentioned for IDE 2.0. At least, now I know one or two sentences more about udev.
There is no equivalent to udev in Windows, I believe. I haven't used Windows for a very, very long time, sorry.
If you can explore USB connections through Device Manager in Windows you should find a leaf for the port in use. You will have to enable user access (Read & Write) for the IDE 2.0 users as a minimum. Again, sorry, I cannot try it out at my end and give you direct feedback.
Unfortunately there is no way to enable user access in the port in use in Windows device manager,so I bought a board the I cannot use for my sketches...its absurd!

As a sanity check, can you try IDE 1.x or the Web/Cloud IDE? Don't lose heart over the board. It has good specs and in due course you'll be happy.
FWIW, I stayed away from IDE 2 during the earlier releases of this product - too many issues and too little support. I thought that at least with GIGA someone would have done some basic/fundamental Hello World Quality Assurance check with IDE 2 but I was sadly mistaken.
Of course, this is par for the course in the industry even when building customer facing apps owing the "pressures" and expectations from the customers. If you are into using "maker" solutions you will not be disappointed with the GIGA - let someone like myself who has tinkered in a small way for many years assure you of that premise.
Yes, dfu-util expects 2341:0666! I'm sure that you will soon get a response from Arduino Technical Support. I wonder why Arduino never tested the IDE 2 & GIGA on a clean desktop. Since their QA team already had the port working, they couldn't be bothered with testing from scratch.
I will work on my Ubuntu tasks this afternoon. If I get some time, I'll explore a solution for your Windows environment too.
The usual CAUTION rules regarding changing registry settings apply. Backup and make a note of existing settings.
Your value should be entered in accordance with the narrative in step 4: "You can now change the Value data to 4 to disable the USB ports and change the value to 3 to enable the USB ports."
Of course, using Method 2 in the same article is a safer way to work with the registry as long as you have proof-read the script files diligently.
Subsequently, I was able to upload from IDE 2.0.3 to GIGA without any error message. So, your solution too will require the USB port to be enabled for Read/Write for all IDE 2.0 users on your platform.
@baqwas ,thanks for your suggestions,I appreciated a lot your help!Unfortunately the USBSTOR in my windows registry was already set to 3,so my usb was enabled.However I was find this workaround:
I uninstalled the Arduino IDE.
I installed the msi version of the 2.0.4 IDE.
Before to connect Arduino Giga R1, I uninstalled the
"Arduino Mbed OS Giga Boards".
I connected the Giga R1 and then installed again the
"Mbed OS".
Successively I uploaded the Blink sketch with success,and it ran correctly,the only warning was :
"Invalid DFU suffix signature
A valid DFU suffix will be required in a future dfu-util release
".
@baqwas ,I think that in Windows,at the beginning,something was wrong with the USB driver during the installation of "Mbed OS" inside the IDE...sincerely I cannot explain this strange behaviour.
