I burn my program into flash.
At 0x3f7ffc6, there is a long branch instruction:
   LB  _my_start
But the problem just go astray. So i traced the
bootloader. The booloader jumps to 0x3f7ffc6 as
expected. The problem is when i single-step this
instruction, the cpu runs to program address 0x66, at
which location there is a dead loop:
  SB 0, UNC
After that, I found all the LB instructions show the
same symptom.
Does anyone got any idea about this phenomenon?
Any suggestion will be highly appreciated.
