TDA4VM: jtag怎么加锁和解锁

您好，已咨询工程师，这需要一些时间，谢谢！

您使用哪种 XDS？------ XDS110/XDS200/XDS560v2 ？ 

我们项目上不用XDS，一般使用lauterbach调试。

我从文档里找到一章内容，似乎有软件方法可以控制jtag解锁。https://downloads.ti.com/tisci/esd/latest/6_topic_user_guides/secure_debug.html

我更倾向于能够用TISCI API的方式实现功能，

Sending debug certificate to System Firmware

这个有demo吗？

Yes, it is applicable only for HS devices ---> High security devices.

Make sure, the customer use HS device.

As of now, no demo available. But I guess, the doc is in detail and provides all the information. 

我目前按照文档上的步骤做，但是调用 TISCI API后程序会卡死在那。

您好，

以下是工程师的回复：

As the customer uses lauterbauch ( Other than XDS ) , I have forwarded your query to internal team.

Thanks for your patience.

补充一下，我这边倾向于能够用文档里描述的TISCI API的方式实现功能，并不是用lauterbach实现

您好，

以下是工程师的回复：

I have forwarded your query to the right expert on high security devices.

To try this API and test, I do not have any high security devices in hand.

Delay may be due to thanks giving holidays..

Thanks for your patience,

Can you tell us what type of TDA4VM device you are using? Is this a General Purpose (GP) or a High Security (HS) device?

HS device

 HS-SE 。我知道这个方法 software-dl.ti.com/.../secure_debug.html ，问题是我试过没解锁成功
