I can use the IDCODE instruction get the right IDCODE number and the BYPASS instruction also work ,but when I use the EXTEST intruction test the MPC8308 connectivity ,I can't get right data from TDO. The BOUNDARY_LENGTH of MPC8308 is 491.The data first out is 314 bit which I got from TDO ,and the rest are all zero,when I use the EXTEST instruction test the MPC8308.
Solved! Go to Solution.
Check please connection of the MPC8308 Y23 pin. This pin cannot be floated. If this pin is floated, the boundary scan error is possible.
Have a great day,
