Failed to send the auxiliary code data.It may be caused by the following reason:
- The secure boot function of Hi3796M V200, Hi3716M V450, and Hi3796A V200 chips is enabled, but the auxiliary code area is not correctly signed
- If verification of multiple tables is not supported, the tables may be incorrect or the DDR training may be faulty due to DDR exceptions. As a result, the DDR cannot be used.
Failed to download fastboot!
