The typical way one would boot to an SD card on a TS-7400 would be to
modify the linuxrc script to point to linuxrc-sdboot. The default
bootrom on a TS-7400 is FLASHBOOT. FLASHBOOT loads the kernel and
initial ramdisk from the onboard flash where SDBOOT loads the kernel and
initial ramdisk from the SD card. The initial ramdisk on the SD card will
attempt to load a bitstream and some drivers for a TS-7300, this causes a
TS-7400 board to hang. If you want to use SDBOOT you'll need to comment
out the startfpga script from the linuxrc2 script on the initial ramdisk
on the SD card(second partition).
