Silent reboot after loading Android 9.0.0_p2.3.0

Question asked by Jeffrey Marius on Nov 8, 2019

Board Used: IMX8MM EVK DDR4 with CY-43455

Loaded the images using the UUU method and flashed all the images from the following link: https://www.nxp.com/webapp/sps/download/license.jsp?colCode=P9.0.0_2.3.0_ANDROID_SOURCE&appType=file1&DOWNLOAD_ID=null

UUU command used:
uuu_imx_android_flash.bat -f imx8mm -a -e -d ddr4 -t sd -c 28

Bootargs used:
u-boot=> setenv bootargs console=ttymxc1,115200 earlycon=ec_imx6q,0x30890000,115200 init=/init androidboot.console=ttymxc1 consoleblank=0 androidboot.hardware=freescale cma=800M androidboot.primary_display=imx-drm firmware_class.path=/vendor/firmware transparent_hugepage=never androidboot.wifivendor=bcm androidboot.wificountrycode=CN

u-boot=> setenv append_bootargs androidboot.selinux=permissive

u-boot=> saveenv

u-boot=> boot

After booting the system is rebooting again and again. I am not able to see any suspicious logs or crash. But it is to be noted that when before the board could reboot if I provide "ifconfig wlan0 down" then the board stops rebooting. Not sure if this could be a reason because sometimes reboot is happening even with wlan0 down.

Could you please help me resolve the issue?

Attaching the logs as well.
