已经试着刷过CM101-2，刷到最后eMMC识别不到了估计短接CPU针脚时eMMC芯片废了。
后来搞了一个S805的盒子（美如画N15）刷玩客云ROM网卡识别不了，先放一边了。
这次又弄了一个CM201-2 TTL线刷
刷机失败报Failed to download fastboot!
以下是hitool返回信息：

####################################Failed to send the boot data.
- The system fails to run properly due to an error in boot code compilation.
- 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.
- The chip OTP is set to forcibly decrypt the boot image. However, the boot is not correctly encrypted.
- The board DDR is faulty.
Nack error.
- 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.
