TQIMX6UL开发板手动烧写

如果无法从nand启动，在sd卡烧写前要先制作sd启动卡，具体方法可以参考在Linux平台下和Windows平台下制作SD启动卡，如果nand可以启动可以直接从nand启动。
      光盘的烧写镜像在：TQIMX6UL_COREB_CD/出厂烧录镜像合集/Linux 镜像/tqimx6ul_v1.0；烧写镜像的名称可以在uboot 中设置的。如未设置将使用以下默认名称。embedsky.com
镜像内容
默认镜像名称
Bootloader镜像
u-boot.imx
内核镜像
zImage
Dtb镜像
tq-imx6ul.dtb
文件系镜像
rootfs.ubifs
1. 准备一张tf卡，将第一个分区格式化成fat格式。
2. 将烧写的镜像复制tf卡里的第一个分区里（vfat格式）。
$ ls /media/qingleqq/DF15-3F7C/
$ cp u-boot.imx zImage tq-imx6ul.dtb rootfs.ubifs /media/qingleqq/DF15-3F7C/.
$ ls /media/qingleqq/DF15-3F7C/
$ ls /media/qingleqq/DF15-3F7C/*
tq-imx6ul.dtb rootfs.ubifs u-boot.imx zImage
复制代码
/media/qingleqq/DF15-3F7C/为笔者sd卡挂载目录，只作参考，以实际为准。

烧写
(1) 进入下载菜单embedsky.com
1. 如不能从nand 启动，将拔码打到sd 卡启动。插上已经做好的tf 启动卡。否则拔码打到 nand 启动。
2. 接上串口，上电；在以下倒数完成之前按任意键。
