+
+Generate flash.bin using imx-mkimage
+====================================
+
+Copy the following binaries to imx-mkimage/iMX8M folder:
+
+$ cp imx-atf/build/imx8mq/release/bl31.bin imx-mkimage/iMX8M/
+$ cp u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/

+
+If you want to run with HDMI, copy signed_hdmi_imx8m.bin to imx-mkimage/iMX8M.
+
+Before generating the flash.bin, transfer the mkimage generated by U-Boot to iMX8M folder:
+
+$ cp u-boot/tools/mkimage imx-mkimage/iMX8M/
+$ mv imx-mkimage/iMX8M/mkimage imx-mkimage/iMX8M/mkimage_uboot

+$ make SOC=iMX8M flash_spl_uboot
+
+Or for using HDMI:
+
+$ make SOC=iMX8M flash_hdmi_spl_uboot
+
+Flash the binary into the SD card
+=================================
+
+Burn the flash.bin binary to SD card offset 33KB:
+
+$ sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33
+
+Boot
+====
+Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
