Table 51. Troubleshooting for FlashECCLogicCheck()
Returned error bits
Possible causes
Solution
C90FL_ERROR_ECC_LOGIC Hardware Failure.
Hardware error.
2.7.3
Comments
Depending on the errBits value, a single or double bit faults are simulated. When a Flash
read is done, if the simulated error has not occurred, then the API returns the error code
C90FL_ERROR_ECC_LOGIC.
Assumptions
It assumes that the Flash block is initialized using a ‘FlashInit()’ API.
FactoryMarginReadCheck()
Description
This function checks the Factory Margin reads of the Flash. The user specified margin level
is used for reads and the operation is done on the specified blocks. The MISR values
calculated by the hardware is compared to the values passed by the user, if they are not the
same, then an error code is returned.
