S32K344 secureBoot

[liyongfeng]

在ASB模式下实施postBoot，SMR关联app，CR为HSE_CR_SANCTION_DIS_ALL_KEYS时。由于是并行方式所以HSE会释放core 0，同时进行SMR验证。我理解此时app代码已经运行，那么app里能不能通过某个寄存器标志知道SMR的验证结果是成功还是失败呢？

Hi 

Please download the Secure Boot Application note v0.1.1.0 from secure file.

The chapter "4.3.6. SMR core status" mentioned:
HSE system attribute service “HSE_SMR_CORE_BOOT_STATUS” request the SMR verification status and core boot status as Table 14 shows.

Since this document requires signing an NDA, I won’t post the screenshots here. 

You will also find the SMR and Core Boot status in struct hseAttrSmrCoreStatus_t in S32K3X4_HSE_Service_API_Reference_Manual.pdf.

Best Regards,
Robin
