flash the partition "MB1_BCT"

Hi, all:

I modified the pinmux configure.  through the command "sudo ./flash.sh -k MB1_BCT jetson-tx2 mmcblk0p1", the result is ok.
But the product base tx2 is already been used. can not update it through flash.sh and usb data line.
Can I update the MB1_BCT through command "dd" or other ota method?

Thanks.

hello cxl824158933,

if you would like to customize the pinmux and update the TX2, you should perform the whole flashing process to update the board configuration.
please check the documentation, you might refer to Jetson TX2 MB1 Platform Configuration.
thanks
