Hi jiu

reason may be hardware, one can check if power supply cables are reliably attached

also may be recommended to reflash emmc with new image from link

i.MX Software | NXP

i.MX 8QuadXPlus MEK Board Hardware User's Guide

Get Started with the MCIMX8QXP-CPU | NXP

Other reason may be corrupted image and usage SD/MMC manufacture mode

described in sect.5.11 SD/MMC manufacture mode i.MX8DQXP Reference Manual
