The BOOT_SEL[2:0] Configuration on the carrier board is used to determine the boot device by setting the BOOT_MODE[3:0] pins:
BOOT_SEL[2:0]# | BOOT_MODE[3:0] | Boot Device |
|---|---|---|
0 0 1 | 0 0 1 0 | Internal eMMC |
0 1 0 | 0 0 0 1 | Serial Download Mode |
0 1 1 | 0 0 0 0 | Boot from Fuse |
1 1 0 | 0 0 1 1 | Carrier SD Card |
