"Demo Images - SABRE Board based on i.MX 7 Dual" has u-boot / boot / recovery epdc version, but what is different?
How can I build the epdc version?

I will transfer it to a different EPD for IMXEBOOKDC4.
And fix mxc_epdc_fb.c.
How do you build an epd version?

I saw Chapter 10 of the i.MX Linux® Reference Manual.

However, we did not need to change anything except support for splash screen.
Enable below
#define CONFIG_SPLASH_SCREEN
#define CONFIG_MXC_EPDC

Is the epdc version of "Demo Images - SABRE Board based on i.MX 7 Dual" supporting splash screen support?

Moreover, I do not understand the following method.

10.3.7 Enabling an EPDC Splash Screen
 3. Write the firmware file to the SD card at the FAT partition.
     cp epdc_E060SCM.bin [FAT partition on SD card]

The following is the partition of the SD card.
Where can I make a FAT partition and copy it?

Create a new partition with sdb13 with FAT,
Is it OK with the operation below?
> sudo mount/dev/sdb13/mnt
> sudo cp epdc_E060SCM_splash.bin /mnt/epdc_E060SCM.bin
> sudo umount /mnt
