hdd usb boot raspberry pi 4 problem

Sat Aug 08, 2020 1:38 pm

I successfully reflashed the EEPROM of the Raspberry Pi 4 (2gb rev 1.1) and able to boot the pi from my 1TB Toshiba 2.5inch HDD
But theres a problem:
I connected multiple devices to the pi: my 1TB HDD, 500GB HDD, my printer (which is for CUPS) and a 4GB USB Stick
When the pi4 boot with all of those devices plugged in, it wont boot (the light of all the HDDs turned on)
It only boot when i remove all hard disk (except the 1TB HDD which contains Raspbian) and when it booted successfully i plugged those devices back.
So any way to boot the pi4 without unplugging the usb cables?

The total from USB is 1200mA, not per port, if using the Official Power Supply:

How many amps does your 1TB HDD draw on initial boot up ??
The information is out there....you just have to let it in.

My other Linux machines are a ChromeBox & Intel CoreDuo Desktop

Your issue sounds like a bug. Not sure where to report it though :/
