AEDHi 团队、
我正在使用 BOOT_EMAC_FLASH 进行固件升级、我目前的要求是在通过 EPI 模块下载到外部 RAM 之前对二进制文件进行解密、
我集成了代码、但是如何以及在何处 在 BL_STARTUP_CCS.s 文件中添加 AES 128位解密和 EPI0模块引脚中断以启用它
您能否建议如何在 bl_startup_ccs.s 文件中添加这些中断

请帮助我添加这些中断
另外、我对如何配置这个 EPI0模块及其工作文档集有疑问
您好!
我目前正在度假一整周。 我会在今天稍后时间答复你的质询。 请预计会延迟响应。

[报价]您好!
请记住、TM4C1294NCPDT 没有 AES 功能。 请参阅 TM4C 产品选型指南 以了解支持 AES 的器件型号。 请参见下文。
假设您使用的器件型号支持 AES。 在这种情况下、AES 中断将映射到矢量编号111。 请参见下文。
