Package data register on STM32F779

I am trying to have device detection code by reading the "package data" register but I don't get the expected data.

I have a STM32F779I-EVAL board with a STM32F779 mcu. I am reading "0xFFFF" at address 0x1FFF 7BF0. According

to documentation (section 45.3 from RM0410/dm00224583.pdf), it should be a STM32F767/STM32F777 in a QFP208/BGA216

package.

 

So, there is a mismatch.

 

For validation purpose, I read the expected data from the "flash size" register at address 0x1FF0F442.

 

Is there anybody having tried to read the "package data" register on one of MCU part of STM32F7xx family?

 

Thanls
