线刷时遇到 Failed to download fastboot! 哪位大佬帮指点一下
各位大佬好,我的盒子是北京移动的魔百和 cm201-2 板子好是M8291,之前想升级破解,用U盘进行升级,应该是包不对,升级完之后直接变砖,通电灯不亮,无任何反应。后用串口线进行线刷,遇到Failed to download fastboot问题,特来论坛求助大佬,具体问题如下:
使用putty 连接设备,板子上电看到的信息如下:
Bootrom start
Boot Media: eMMC
Decrypt auxiliary code ...OK
lsadc voltage min: 000003E7, max: 000003F6, aver: 000003EE, index: 00000000
Enter boot auxiliary code
Auxiliary code - v1.00
DDR code - V1.1.2 20160205
Build: Sep 7 2017 - 01:06:39
Reg Version: v1.5.2\
Reg Time: 2017/11/15 17:13:15
Reg Name: hi3798mv3dmm_hi3798mv300_DDR3-1866_1GB_16bitx2_4layers.reg
Boot auxiliary code success
Bootrom success
之前使用U盘升级,变砖了,现在板子灯也不亮,上电没有反应,连接串口线之后,打开putty,上电,到“Bootrom success”这儿就卡主了,没有出现System startup。在putty窗口中点回车,或者输入,也没有任何反应。
使用HiTool 进行线刷时,输出如下:
串口已经连接,请给单板上电,若已经上电,请断电后重新上电。
Bootrom start Boot Media: eMMC ############Timeout error. Failed to send the head frame. Failed to send the auxiliary code data.
Boot head format invalid. Failed to send the auxiliary code data.It may be caused by the following reason: 1. The secure boot function of Hi3796M V200, Hi3716M V450, and Hi3796A V200 chips is enabled, but the auxiliary code area is not correctly signed 2. 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!
看提示是secure boot function of Hi3796M V200, Hi3716M V450, and Hi3796A V200 chips is enabled,是启动了安全防护导致的吗?但是我的板子明明是hi3798mv300,不是Hi3796M V200, Hi3716M V450, and Hi3796A V200 ,为什么会出这样的提示?
哪位大佬知道是哪里的问题,麻烦指点一下,先谢谢了。
