Hi All,
I am planning to configure imx6 into a boot from eMMC always.
my configuration is
BOOT_MODE[1:0] set always 00.
and I will burn the BT_FUSE_SEL into 1, efuses accordingly to boot from eMMC.
So now my questions are,
1. Is it possible to reflash the eMMC later as my firmware changes? if yes please let me know the procedure?
2. I want to interface 2 parallel cameras (10bit mode) into imx6
Camera1 pin connections I have no issues.
Camera 2 pin connection I have added here, in this pins list few pins are shared with boot configuration pins.
is there a problem if I use these pins to connect my camera. anyways I am planning boot from eFuses.

Thank you in advance.
Thank you for your support.
1. If you plan to use the Linux BSP by NXP, you can use the procedure, described in the "Downloading images using U-Boot" section of the corresponding i.MX Linux User's Guide document.
Otherwise, you have two options as follows:
- add a simple switch to your hardware to be able to switch the BOOT_MODE[1:0] signals to 01 to boot the processor in the Serial Downloader mode, then use the regualr procedure with UUU tool;
- use an external eMMC programming tool.
2. There is no problem to use these pins for CSI function as you describe.
Best Regards,
Artur
