I have designed a board using P2020,the hardware config pins are connected to the CPLD,.The power up sequence is refer to the P2020RM.When the power up , 1) P2020 cannot  be connected to the emulator(trace32) ,cannot click "up",cannot click "stop" to check PPC register

2) p2020 is at the status of "asleep",it cannot go to the status of "ready". /HRESET pin drive by cpld , Meeting document requirements,but p2020 cannot boot from flash.
