[参考译文] AM6442：AM64x OTP Keywriter 未知调试响应代码

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1488583/am6442-am64x-otp-keywriter-unknown-debug-response-codes

工具与软件：

我在开发套件上使用 AM64x 处理器运行 OTP Keywriter。  我使用的是 OTP Keywriter 版本10.00.08和 MCU PLUS SDK 版本10.00.00.20。

我正在尝试对 SMPK 和 BMPK 字段进行编程、并且收到无法解释的调试响应。 我能够成功地对"JTAG Disable"和 MSV 字段进行编程。 我还可以告诉大家、我的 SMPK 和 BMPK 哈希已按预期进行解析。  

我已经在  SMPKH 第1部分和 BMPKH 第1部分字段中分别收到了以下调试响应：0x10000和0x800。  

我在本文档中找不到有关这些调试响应的任何信息、我一直在引用这些信息来解释调试响应代码： https://software-dl.ti.com/tisci/esd/latest/2_tisci_msgs/security/keywriter.html#otp-key-writer-error-code。

有人可以帮助解决什么问题吗？ 尝试对 BMPK 和 SMPK 字段进行编程时、附件为 m3日志(为确保成功、已删除实际哈希)：

那么、当仅尝试对 SMPK 字段进行编程时 (为确保简洁性、已删除实际哈希值)：
