Hi Kita,

Fapi_checkFsmForReady() function checks if flash state machine has completed an erase or program operation or not. Could you please call ClearFSMStatus(); function before issuing programming command?

Hi Rajeshwary,

The customer wants to know:

1.  Is it possible that CPU stuck in {Fapi_CheckFsmForReady()!= Fapi_Status_FsmReady} and can't exit?

2. if there is some method to exit this function compulsorily if it's stuck in this function Fapi_CheckFsmForReady()?

Thanks!

Best Regards

Hi Kita,

This should not happen normally it comes out of the while loop. Is the user trying to read and write from the same bank?

If not, then user can implement timeout as specified in the datasheet. Please note that if FSM is busy then users next erase or program command will fail.

Did you tried to call ClearFSMStatus(); function?

Rajeshwary

Hi Marlyn,

The customer said that there is no detailed introduction about the content of vector. Could you help to check what content is in the vector? Is the reset command also in this address?

Best Regards

Kita

Hi Kita,

It is the bootrom entry point. On reset, the first fetch from C28x is from there. 

What do you mean by 'reset command'?
