AM5729: ethercat slave with PRU1

Part Number: AM5729

software:PRU-ICSS-EtherCAT_Slave-01.00.08.01、ti-processor-sdk-rtos-am57xx-evm-06.03.00.106

hardware:TMDSIDK5729

I generated the project file as described in https://software-dl.ti.com/processor-industrial-sw/esd/docs/indsw/EtherCAT_Slave/01_00_10/PRU_ICSS_EtherCAT.html#introduction

I can run ethercat slave with PRU2 and I can scan it in twincat, but when I run salve with PRU1, I can not scan it. I want to know why?
