1. The system fails to run properly due to an error in boot code compilation.
2. If the secure boot function is disabled and boot rootkey is set for the OEM, the boot image is encrypted, but the boot rootkey used for encrypting the boot is different from the boot rootkey burnt to the OTP.
3. The chip OTP is set to forcibly decrypt the boot image. However, the boot is not correctly encrypted.
4. The board DDR is faulty.
Timeout error.
5. The boot code does not support the type of the flash memory to be burnt. If the boot print function is enabled, you can view the printing information through the serial port, showing that the current flash memory type is not supported.
