TDA4VM: cannot restart

Hi team,

Here's an issue from the customer may need you help:

The system is started in eMMC boot mode, the system is restarted by executing the reboot command, everything else is fine, but the shutdown is not complete after the kernel calls Power down.

Try to reset from the bootloader, but fails. Also trying boot from the TF card, reboot is implementable. The following error is reported:
