Did you only write in DAT0 due to the constraints of the RT809H being DAT0?
Also, Where you replaced your eMMC with another eMMC, im attempting to replace and eMMC with a Micro SD Card - What do you think about this? Could work or never?

I have seen many posts where the eMMC can be read via a SD card reader, however can the opposite be achieved?

Read/Write a Micro SD Card from an eMMC Socket.

I have a Motherboard with a Kingston BGA153 ball socket, using HS400 bus mode, which is 8bit, as Micro SD is usually 1bit or 4bit mode, I accept that a loss of speed in read/write will occur, but I would sill like to convert.

Theoretically speaking, Im thinking if I hard solder DAT0-3 from eMMC to SD Card Reader, this should force 4-bit mode, or only DAT0 to force 1-bit mode.
