Hi Kevin,

ad.1. will Fapi_doBlankCheck() work when EXEONLYSECT is enabled on that flash location?

ad.2. Can you send me a link to the BootROM documentation where SafeCRC funcion is described? I cannot find any document about API for that.

The most important question for me is still:

Yes, you can perform erase and program operation on the EXEONLY sectors but read verify may not work.

Also on SafeCRC , high level detail is already mentioned in security section of device TRM. The function detail is not provided to user.
