器件型号：PROCESSOR-SDK-AM62A 工具与软件：
您好！
在 DFU 使用我自己的密钥将 tispl.bin_HS 引导到 HS-SE 器件后、我遇到问题。 根据此输出、A53 SPL 似乎未运行。

这些是我要对自己的自定义密钥执行的步骤。
1.将 custMpk.pem 替换为从 otp_keywriter 生成的 smpk.pem
2.使用 core-secdev-k3/scripts/secure-binary-image.sh 从/prebuilt-images 中执行 signed bl31.bin.unsigned 和 bl32.bin.unsigned
3. 从 CCS MCU SDK 构建 ipc_rpmsg_echo_linux_am62ax-sk_r5fss0-0_freertos_ti-arm-clang.out、并使用相同的脚本对该映像进行签名。
(我构建该映像的原因是 /prebuilt-images 中的 ipc_echo_testb_mcu1_0_release_strip.xer5f 显然已使用默认密钥进行签名？)
4.我更改了顶级 Makefile 中的路径以指向这些已签名的二进制文件
UBOOT_ATF=$(TI_SDK_PATH)/board-support/prebuilt-images/bl31.bin.signedCustom UBOOT_TEE=$(TI_SDK_PATH)/board-support/prebuilt-images/bl32.bin.signedCustom UBOOT_DMFW=$(TI_SDK_PATH)/board-support/prebuilt-images/ipc_rpmsg_echo_linux_am62ax-sk_r5fss0-0_freertos_ti-arm-clang.xer5f.signedCustom
5.在这之后只是做一个"make u-boot"和"make sysfw-image"
我还使用以下日志确认 DM FW 正在运行

在另一个电路板上、我能够使用默认 TI 密钥成功引导至 U-boot、而这是输出。
