TMDSLCD6748 串口烧写

开箱测试TMDSLCDK6748，烧写程序报错

将编译好的程序通过 AISgen 烧写报错

步骤如下：

打开AISgen选择C6748配置文件

转换生成ais文件

通过串口烧写

板子拨码开关选择串口启动

点击start 按钮复位板子，显示IO错误

尝试擦除Nand Flash

发现软件报错
和文档描述不一致

Nancy Wang：

看步骤应该是没有问题，换一台电脑试一下或者重启再试一下，擦除指令。

以下链接 2.2 Serial Boot and Flash Loading Utility部分的说明也参考看一下。

经过尝试采用 \C6748_StarterWare_1_20_04_01\build\c674x\cgt_ccs\c6748\lcdkC6748\nand 工程修改代码将整个NAND擦除一遍，然后采用sfh_OMAP-L138.exe工具烧写NAND

sfh_OMAP-L138.exe -flash -p COM4 -baud 115200 -v  -targetType C6748_LCDK uartEcho.ais uartEcho.out -flashType NAND

最后成功烧写并通过NAND启动程序
