[Solved] SSD Boot from Quad sata Hat

Hardware and peripherals SATA HAT
18

I am not sure if any of these could be the problem.

  1. I updated my firmware to have different serial numbers How to upgrade F/W with jms561 under Windows
  2. I tested my drive with as an external usb device first to make sure it booted via the USB. There are plenty of resources that show this
  3. My full config looks like this
BOOT_UART=0
WAKE_ON_GPIO=1
POWER_OFF_ON_HALT=0


[all]
BOOT_ORDER=0xf41


[config.txt]
gpio=25,25=op,dh
gpio=26,26=op,dh

The BOOT_ORDER configuration details are here https://www.raspberrypi.org/documentation/computers/raspberry-pi.html#raspberry-pi-4-bootloader-configuration
0xf41 means Try SD first, followed by USB-MSD then repeat (default if BOOT_ORDER is empty). So remember to remove your SD Card

The lights should turn on almost instantaneous if this doesn’t happen check your firmware version only the later versions of the firmware allow the [config.txt] section
