I have been using the default 6 in screen with the Ebook daughter card and an IMX6 SOLOLITE. I have been able to successfully use the 6 in screen but am trying to connect a different size screen. Luckily both screens use a JST connector 39FXL-RSM1-S-H-TB. The list of pins and signals on the E-paper screen and daughter card output are almost identical with a few that are in a different order. For this reason it does not work to simply connect the other screen. I was wondering if it was possible to change the pin configurations on the daughter card to match what the E-Paper screen accepts? For example defining that a VDD, digital power supply driver, be a pin 2 instead of a pin 5 etc. I have attached the data sheet for the daughter card. The relevant component is on page 8.
