I may have need to run my iMX6D based hardware with only the lowest 16-bit device active on the data bus.
To confirm that this is possible, I'm trying to configure my sabresd board in that mode.
I thought all I had to do was change the DSIZ bits in the MMDCx_MDCTL register
(part of DCD data) to 00. When I do that (in u-boot), I am then not able to do a USB-based download.
Is there something else that needs to be changed?
