MCU is MC9S12XEQ512,it's about the offical bootloader.
While upgrading,if S Record's load address is 0x7FFFE0,it will write *(u16 *)(&data) into 0x7FEFF8.
This means the content of 0x7FFFE0+24 = 0x7FFFF8 is the app's Reset vector.
But in the MCU datasheet,FFF8 is the interrupt vector of unimplemented op-code trap.I think,the bootloader should write the content of 0x7FFFFA into 0x7FEFF8,cause it's the COP watchdog reset.
Is it right?
