TQIMX6UL开发板手动烧写

embedsky

      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。

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）。

1. $ ls /media/qingleqq/DF15-3F7C/
   
2. $ cp u-boot.imx zImage tq-imx6ul.dtb rootfs.ubifs /media/qingleqq/DF15-3F7C/.
   
3. $ ls /media/qingleqq/DF15-3F7C/
   
4. $ ls /media/qingleqq/DF15-3F7C/*
   
5. 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

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。

1. ......
   
2. Normal Boot
   
3. Hit any key to stop autoboot: 1 #这里是1 秒
   
4. ......

复制代码

按任意键中断自动启动，进入命令行菜单

1. Out: serial
   
2. Err: serial
   
3. Net: FEC0
   
4. Normal Boot
   
5. Hit any key to stop autoboot: 0
