Hi Peng, I'm working with an IMX8MM with U-Boot master + your v3 i.MX8MM-support series.

Did you need to enable DM_SERIAL? After enabling DM_SERIAL build fails during image creation: MKIMAGE u-boot.itb ./tools/imx8m_image.sh spl/u-boot-spl.cfgout 1 26061+0 records in 26061+0 records out 104244 bytes (104 kB, 102 KiB) copied, 0.0458568 s, 2.3 MB/s MKIMAGE flash.bin Not support no fit arch/arm/mach-imx/Makefile:151: recipe for target 'flash.bin' failed If I hack using_fit=1 into tools/imx8mimage.c I can build flash.bin but it does not boot. Am I missing some additional necessary patches to tools?
