Arduino Uno Q 4GB Single-Board Computer boot problem

I got the Arduino Uno Q 2GB and 4GB boards but having problems doing Single-Board Computer boot.

Every time I try it loops trying to boot up in to desktop but can not complete on the 4GB board but after 3 reboots the 2GB goes into desktop.

Is there a fix for the boot up problem??

My guess is the USB power supply is not providing enough current. I am using a USB-C PD power supply that says it can deliver 5A@5V for an Uno Q 4GB. The board boots every time. My previous power supply said it could deliver 3A@5V but I had difficulty booting like you describe.

Yes, sounds like power problem..

I got this power supply using this dongle..

Haven’t had any troubles so far, knocks on wood..

good luck.. ~q

Mine is booting reliably only with thick cable (it should be 5V 3A, not 12V 1A or any other pd combinations). And good charger of course, like Xiaomi 68W

I have not had an issue with my 4gb Uno Q. I have not done much with it yet. I am using a 3A/5v power supply.

Unfortunately it is no longer in stock. I got it back in October.

I have purchased a second power adapter but it just arrived and I have not tested it yet. I certainly hope it works.

I'm using the "Anker 736" (model number A2145) 100 W charger as the power supply for my UNO Q when using it in SBC mode. I'm using the cable provided with the charger. I haven't had any problems.

I assume the capabilities of this charger are far surplus to requirements, but figured it was worth getting something very capable in order to ensure it will be up to the task for any other more demanding applications I might use it in.

I am using an 65Watt USB-C power supply.
It works on the 2GB after 2-3 reboots. but not 4GB

It works as an normal arduino board when connected to PC.

It only failed trying to go into desktop mode.

Suspect its defective at this point and giving up on Uno Q and returning it

The problem might be caused by using a low quality USB cable that is not capable of providing sufficient current. The cheap cables have very fine gauge wires that simply aren't up to the task of powering this more powerful board.

If you have another cable on hand, try using that one to see if it solves the problem.

tried 4 different types. from the ones delivered from arduino kits to an Iphone USB-C type

Found the USB-C on the board to be defective.

Unit going to be returned for an replacement
