I recommend referring to the article: Installing NVIDIA JetPack with L4T on Apalis TK1. Although note that you will not need to follow many of the instructions to flash the rootfs onto the on-board eMMC of the module if you plan instead to boot the rootfs from an SD card.
As the thread linked by Marcel states, there is already an SD boot command in the bootloader and you can partition your SD card as described (with a FAT32 parititon and an ext4 partition). The uImage, dtb & bct files go on the FAT32 partition. The L4T rootfs is extracted on the ext4 partition.
Then when you boot the module, halt boot at the bootloader and enter 'run sdboot'. If you want to make sdboot the default, you can edit the bootcmd variable in the bootloader.
