Odroid XU 4 rebooting problems fresh image

Unread post by field3d » Tue Apr 09, 2019 11:22 pm

I have the Odroid XU 4 and I want to install the new ubuntu with os 18.04 from the default site. The problem is I’m presenting problems since two other images and I was thinking it was my old version of Ubuntu but is not. The problem is if I plug the odroid original usb wifi dongle and a usb keyboard at the same time crash. When is booting I see the regular text of booting and after some time crash and reboots.If I uno,uf all the usb devices and turns if for 30 seconds it will turn on and boot perfectly. After the reboot is successfully I can connect the keyboard only and can reboot fine but most of time not, If I plug the usb wifi dongle worst is impossible boot. I bought the Odroid Xu 4 with with power supply included ir says 5V 4A. What could be the problem?

I solved the issue but I will comment if someone presents the same problem. It was the power supply is not enough to sustain the 4 A. I plugged a 15 A power supply and ran more than perfect. It could work with the 6A PSU also I suppose.

Did you buy our official 5V/4A PSU?

or

Can you please share a picture of your bad 5V/4A PSU?

Yes it doesn’t work. Is 4A

I talked with the seller in Amazon and is that type of sellers that makes a hit and run and like it has more than a month they don’t do anything. Anyway I bought this:

But do you think is defective the 4A amperes PSU or is a fake? Actually I’m working temporary with a 15A PSU because is so big.

that 30 watt supply should be ok given the fact that you have 10 watt`s overhead..xu4 will be ok with that..u may lose 5 watts in efficiency .no biggy..
the specs given from your lower link look ok..never seen efficiency rating`s used in that manner though "a six or as it is written VI "
but in the spec sheet it is given @84%..i usually look for a supply in the mid 90% bracket my self...
i think xu4 should often have a 30 watt 5 volt supply because more often than not,
the usb3 port`s are asked of there full potential with hdd`s attached and other devices as well as with high cpu load`s..etc..etc

your 15 amp supply of coarse it will work... but it is over-kill

It seems to be our official PSU. We will check it more carefully.
Give me a link of the Amazon product page. We will try to find who sold it.

It is hard to know the real seller with the link.
I think you can find the seller information on your invoice.
