一、Instructions：
1.The board no CPLD，LSDK is LS1043ARDB 1909
2.The POR circuit refers to FRWY-LS1046ARDB. Please refer to the following picture for details.
3.The RCW part refers to the following picture for details.
4.The software starts from SD card.
二、Problem description
1.If we delete ADM8611 and keep R199,the system can start and work well,but RESET_REQ_B keeps low all the time.
2.The following information has nothing to do with whether there is an SD card.
1).Board power on,RESET_REQ_B output high，ADM8611 output high after 240mS and CPU_PORESET_B becomes high。But 12mS later，RESET_REQ_B output low and keeps 5uS。And so on and so forth.
2).The following picture is RESET_REQ_B vs CPU_HRESET_B。
三、More informations
1.The power on sequence G1VDD(yellow) vs CPU_PORESET_B(purple)
2.The power on sequence G1VDD(yellow) vs RESET_REQ_B(purple)
