+## 简介
+
+介绍通过Trac32使用secure debug功能
+该功能支持JTAG模式，不支持SWD模式
+芯片匹配debug key成功后开启debug接口
+
+##硬件连接
+
+- e3_gateway参考板
+- Trace32
+
+##注意事项
+- 确认板子JTAG功能正常，对于e3 gateway参考板需要去掉TDO/TDI上的两个电阻。
+- 需要通过fuse工具烧UID,debug key和使能secure debug。
+- 接口如果是SWD,需要修改为JTAG。
+
+##测试方法
+当板子以以下方式烧UID,debug key和使能secure debug.
+Debug Key:
++-----------------------+------------+------------------+
+| name                  | fuse addr  | fuse value       |
++-----------------------+------------+------------------+
+| UID[0, 31]            | 0x1010     | 0x12345678       |
+| UID[32, 63]           | 0x1014     | 0xABCDEF88       |
+| SEC_DBG_CFG[31, 0]    | 0x1280     | 0x74657374(key0) |
+| SEC_DBG_CFG[63, 32]   | 0x1284     | 0x6b657930(key1) |
+| MSIC_CFG3/SDBG_MODE   | 0x12b0     | 0x00800000       |
++-----------------------+------------+------------------+
+
+脚本拖入trace32.exe并执行
+CD.DO 本地路径\e3_attach_sf.cmm
+
+提供错误的debug key则无法执行通过。
