So I'm having issues getting the USB boot mode working on my new raspberry pi 3b+ and a couple of different SSD's
I'll first go through all the things that I've done, and what I'm seeing.
- Installed Rasbian on an SD card
- Setup the USB Boot Mode in accordance to these steps from the SD card --https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md
- Reboot the R.Pi to write the OTP bit
vcgencmd otp_dump | grep 17:command checks out and I get the verified result
- I flash my SSD with etchio with the exact same image (I'm using rasbian lite) as the original on the SD card
- I boot the R.pi with the SSD plugged in via a SATA to USB 3.0 connection and the SD card removed.
- I see the "power" indicator on the SATA/USB connector light up for 2 seconds during the check cycle of the R.pi, but it turns off immediately after and doesn't boot leaving me with a black screen.
And thats where I leave basically.
I tried doing this with TWO different SSD's too...
https://www.amazon.com/gp/product/B01N6JQS8C/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1 -- A kingston 120GB SATA 3 SSD
And I'm using this Rosewill USB 3.0 to SATA 3 adapter cable -- https://www.amazon.com/gp/product/B06WVDK9QD/ref=oh_aui_detailpage_o02_s01?ie=UTF8&psc=1
The only thing I can possibly think is that the USB to SATA 3 cable isn't compatible? But I honestly have no idea, I'm at a loss. I just ordered a new one to test this theory.
It's probably worth noting that I also flashed a 32 GB Lexar Flash Drive and it worked! So it confirms that the USB Boot options works, but there is a problem with the SSD's.
I'm skeptical about power consumption, but I'm really no expect in this area.
Thank you all in advance
