radsfaninlv,

That has confirmed what David and I suspected the problem was.

u-boot-2017.07-tld-1 supposed to show

PogoE02> usb reset
usb reset
resetting USB...
USB0:   USB EHCI 1.00
........
Use USB retry period from the environment: 30 second(s)
1 Storage Device(s) found

If the usb_ready_retry env is

usb_ready_retry=30

So check your power supply cable and perhaps at the power coming to power supply and out of power supply to the board (i.e how much voltage and AMP, is it enough power?).

I tried changing the power cord and moving to a different room with the same result.

I removed the power supply board and plugged it in and took some measurements where it is printed GND and 5V (the back of the plug receptical that connects the power supply board to the main board). i got the following results:

Volts AC: 7.1
Volts DC: 0.1
mAmps: No reading

Is there another place where I should take the readings?
