Hi Ivan Matrakov , In continuation to the above mail, in uboot include/configs/am335x_evm.h contains #define CONFIG_EXTRA_ENV_SETTINGS \ "loadaddr=0x80200000\0" \ "fdtaddr=0x80F80000\0" \ "fdt_high=0xa0000000\0" \ "boot_fdt=try\0" \ "rdaddr=0x81000000\0" \ "bootpart=0:2\0" \ "bootdir=/boot\0" \ "bootfile=zImage\0" \ "fdtfile=undefined\0" \ "console=ttyO0,115200n8\0" \ "partitions=" \ "uuid_disk=${uuid_gpt_disk};" \ "name=rootfs,start=2MiB,size=-,uuid=${uuid_gpt_rootfs}\0" \ "optargs=\0" \ "dfu_alt_info_mmc=" DFU_ALT_INFO_MMC "\0" \ "dfu_alt_info_emmc=rawemmc mmc 0 3751936\0" \ "mmcdev=0\0" \ "mmcroot=/dev/mmcblk0p2 ro\0" \ "mmcrootfstype=ext4 rootwait\0" \ "usbroot=/dev/sda2 rw\0" \ Please look at the text red in color(I did not make any changes.). I have tried to build the uboot with this config and boot with this. Still it is searching for uImage. Then I tried to build linux kernal with make tisdk_am335x-evm_defconfig make uImage Then I copied this image to rootfs/boot folder. Then the log I am seeing is given below.
