Return values

Troubleshooting

The trouble shooting given here comprises of hardware errors and input parameter error.

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.

2.7.3

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.
