Hi,

I'm using MPC56xx. My software uses Flash A area. When I got an error on my project I had checked the flash memory and saw 0x00 on unused flash area (Flash B). (But sometimes I need to read these area) I handle these data in the interval of 0x00000200.  i.e. 

 

000C03E0FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF0B

000C03F0FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFB
000C040000000000000000000000000000000000DA
