Whilst doing the safety analysis of our project, we have been driven by the recommendations in the Safety Manual SPNU550B. Of particular interest are the following sections:
7.35 FEE Contents Check by Hardware CRC
7.39 Flash Contents Check by Hardware CRC
Our analysis links these to the following Safety Feature IDs;
- FEE2A
- FEE2B
- OTP4B
- FLA5A
- FLA5B
This is all fine, what is confusing me is that I can't find cover for OTP4B in the SafeTI
Hercules Diagnostic Library; all of the other IDs trace to the SL_CRC_Calculate fn whereas:
| OTP4B | Periodic hardware CRC check of OTP contents | Not available | Not in scope of this release |
Given that the input args to this fn are an address and a count, how come it doesn't trace to OTP4B?
