Hi, 

I have ported the safeTI library demo to my application. All the self tests are working fine.

I would like to test the failure of Flash memory. I am not sure how i can do that. I tried to read the memory 0x2000 0008  in my application, but i did not get any data abort exception. 

Thanks in advamce.

best Regards,

Sreekanth reddy challa

    To inject an ECC error at a specific location in the flash you need to use the linker generated ECC
    (because auto-generated ECC won't put in 'errors')
    See this section
    8.4.12 Error Correcting Code Testing (--ecc Options)
    in SPNU118 (the assembly tools guide)
