TMS570LC4357: FEE driver reading data after formatting or invalidating gets into strange mode

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

I am testing FEE read and write example code from halcogen with little modification. In the first run I am formatting and reading data at block 1. Which returns an error code of BLOCK_INVALID and data is 0's. This is correct since I have no data written into block yet. Then I write the data synchronously and read back. Everything looks good here. Then when I power cycle or soft reset and try to just read data I receive an error code of BLOCK_INVALID which is strange.  This behavior is also seen when invalidate a block , write valid data and read valid data in first run and then after reset I get same error.
