可文档上不是这样说的啊,我参考的是i.MX 6Dual/6Quad SABRE-SD Linux User's Guide.pdf
4.1 How to Enter Serial Download Mode for MFGTool
No dedicated boot dips are reserved for serial download mode on MX6 SABRE-SD
boards. Therefore, a tricky method is used to enter serial download mode. For example,
set boot mode as SD3 boot (SW6 dip 2, 7 on others are off). Do not insert SD card into
SD3 slot, and power on the board. After "HID- Compliant device" is detected, it means
the board has entered serial download mode, insert the SD card into SD3 slot. Another
way to do this is to configure an invalid boot switch setting, for example, set all the dips
of SW6 to off.
你是对的,我换成00001100,下载到SD3成功了,但boot的时候,要飞思卡尔的登陆口令,是啥情况:
