   - In the above example you can modify fsload to load for your storage interface, device, and filesystem (ie "setenv fsload 'fatload mmc 0:1'" for loading from fist mmc controller first partition fatfs filesystem)
+
+=== For Venice
+
+In your buildroot config enable:
+{{{#!bash
+BR2_TARGET_ROOTFS_CPIO
+BR2_TARGET_ROOTFS_CPIO_GZIP
+BR2_TARGET_ROOTFS_CPIO_UIMAGE
+}}}
+
+Make and copy the necessary files to your hosted directory: 
+{{{#!bash
+TFTPBOOT=<your hosted TFTP dir>
+cp buildroot/output/build/linux-v5.4.45-venice/arch/arm64/boot/dts/freescale/imx8mm-venice*.dtb $TFTPBOOT
+cp buildroot/output/images/Image buildroot/output/images/rootfs.cpio.uboot $TFTPBOOT
+}}}
+
+Boot your Venice, break out in the bootlaoder:
+{{{#!bash
+setenv serverip <your server IP address>
+setenv ipaddr <the IP for your board>
+setenv bootargs "console=${console},${baudrate}"
+setenv fsload tftpboot 
+setenv fdt_file1 imx8mm-venice-gw72xx-0x.dtb #or whichever dtb your board requires
+$fsload $fdt_addr_r $fdt_file1 && $fsload $kernel_addr_r Image && $fsload $ramdisk_addr_r rootfs.cpio.uboot && booti $kernel_addr_r $ramdisk_addr_r $fdt_addr_r
+}}}
