主芯片是海思的Hi3798MRBCV30100000H，根据https://www.ecoo.top/histb.html设备支持列表查看，支持移动新魔百和M301H。但可能我的主芯片特殊吧
(CW,SM代工的盒子可以)
报错信息如下
############Timeout error.
Failed to send the head frame.

Boot head format invalid.
STATE:0x00000000 0x00000000 0x00000000 0x00000000
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.
