Hello,
Thank you for writing.
Probably, you are getting a little bit confuse. The only mode that manufacturing tool can detect the imx6, is using the serial download mode (you can access this mode changing the SABRE-SD SW6 to 00001100 ). That is why, after you downloaded the image, the manufacturing tool is not detecting your imx6. But, if you want to boot your new burned image, you need to change the boot switch to its respective configuration:
Change "Boot Switch(SW6)" to 11100110 (from 1 bit to 8 bit) to switch the board back to eMMC 4-bit boot mode.
Change "Boot Switch(SW6)" to 11010110 (from 1 bit to 8 bit) to switch the board back to eMMC 8-bit boot mode.
Change "Boot Switch(SW6)" to 01000010 (from 1-8 bit) to switch the board back to SD Card boot mode.
Furthermore, can you please be more specific with the UUC problem? What you mean with UUC?
Best regards,
Diego,
