https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1452636/am623-custom-board---key-writer

器件型号：AM623

工具与软件：

您好！

成功更改 keywriter_setvpp ()函数以启用1.8 Vpp 后,我仅使用./ gen_keywr_cert.sh -t tifek/ti_fek_public.pem --mSv 0xC0FFE 创建了一个证书以用于测试。

并进行了刷写；现在、它仅通过 HS-SE 安全映像进行引导。

问题1。在刷写 ti_fek_public.pem 后是否成为 HS-SE ？

问题2：如何检查 vpp 不闪烁的键,有没有任何功能,我可以评论和测试?

问题3。刷写自定义主板不能自动重启后、如何调试此问题？

此致、

-RJ

您好！

1.否、该器件仅在对 KEYREV 字段进行编程后才转换为 HSSE。

您可以参考以下常见问题解答来检查器件类型：

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1228618/faq-am6xx-how-to-check-if-device-type-is-hs-se-hs-fs-or-gp

2.您可以注释`keywriter_processKeyConfig`函数、如下所示：

diff --git a/sbl_keywriter/am62x-sk/r5fss0-0_nortos/main.c b/sbl_keywriter/am62x-sk/r5fss0-0_nortos/main.c

3.请详细说明刷写步骤、启动模式等问题

这是我还想,但发生的是定制板被转换为 HS-SE ,

您好！

使用该证书是不可能的。

相反、您可能错误地启动了使用不同证书构建的 Keywriter 二进制(用于对密钥、keycnt 和 keyrev 进行编程)、从而将 SoC 转换为 HSSE。
