Thank you.

That helps verify that the memory map is similar (or the same) as the 4GB touch screen devices.
Note the memory start address of the 'main' and the 'diags' system (still the same).
Also that the names of those two boot commands has remained the same.
(u-boot is scripted, the scripts are stored in these environment variables)

You should expect that it will take our source code readers here some time to read enough of it to determine just what happens during 'erase all'.

Since the device will only run using the internal RAM, most likely will have to use iMX-Loader or usb-loader (mostly the same) to communicate with the start-up code stored in the SoC's internal ROM.

Somewhere here is a thread about installing a larger eMMC device.
Being brand new, it had to have all of the environment and u-boot loaded using a lower level application than fastboot.

That thread should give us the directions, which when modified for this situation, will have to be followed.
