How to configure the SW6 DIP switch to flash a program image on IMx6DQ SABRE SDB target? Is there any documentation availabe for DIP swich configuration for the SABRE SDB board? I am able to load a image using the SD card.
The i.MX6 SDP / SDB design does not support the Serial Downloader mode directly.
According to section 4.1 (How to Enter Serial Download Mode for MFGTool)
of "i.MX_6Dual6Quad_SABRE-SD_Linux_User's_Guide.pdf" :
"No dedicated boot dips are reserved for serial download mode on i.MX 6 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
that 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."
