TI中文支持网加密版本的6748，解锁jtag报错如下：

请问jtag.bin文件是用SecureHexAIS_OMAP-L138.exe转换的吗？

感谢您的回复!!
是使用的SecureHexAIS_OMAP-L138.exe和GenericSecureUartHost.exe这俩工具

您好，板子是自己做的，能出现bootme，能否说明串口没问题?

是不是这个文件jtag.bin有问题. 发上来，或者打开截个屏上来看一下。

收到bootme说明DSP到PC的传输没问题。
检查一下串口硬件，是不是PC发送到DSP线路有问题。之前有客户查出来是电平问题。

您好！感谢回复
我用示波器抓了下波形，收发都是正常的，您这边有可用的ais文件提供吗
user5342663：
回复 Shine:
我这边的现象就是：示波器可以抓到两段波形，bootme正常，然后紧接着就是一段波形。从pc发给DSP，之后就和上述报错情况一致了

试试附件，在我这是可以的。

这个是通用的吗？
我的开发板是自己画的，boot模式是串口0
