With the current firmware being pulled for the RPi3, recent revisions of the RPi hardware, such as the 3 B+ will fail to boot. The issue is exhibited as when RPi 3 B+ receives power and attempts to boot, the power LED will turn off and the ACT LED will flash 8 times. According to elinux.org troubleshooting guide[0] this correlates to an SDRAM initialisation error that can be fixed by updating the firmware. After updating this firmware the power light stays on, and UBoot can be seen booting.
