Bootloader: C:0x0000 - C:0x7FFF Manages CAN-Communication and in-field update. Application C:0x8000 - C:0xEFFF Applications is controlled with bootloader over CAN 2.0. Compiled both seperatly and merge the Hex-file. Interrupts and function calls work. At level of 8 successive funtions calls the acces to an struct in Applications XDATA mem is incorrect. The expected pointer is not given. Any adwise?

Executing applications ?C_START when switch from bootloader to application.
