The Colibri iMX7D in the Toradex web shop will not support EPDC since it uses an iMX7 part without EPDC.
However, our early samples of the iMX7D used the SoC part with EPDC and we plan to continue to produce this variant. So, yes, there is a variant of the Colibri iMX7D with EPDC which we expect to maintain into the future. It will require changing the standard pinout of the module. We have not tested the interface ourselves nor do we officially support the interface in our BSPs; but we have a customer already employing EPDC with Colibri iMX7D in their prototypes.
The pinout for EPDC is listed in the Colibri iMX7 datasheet as well as in the pinout designer tool.
Please contact your local Toradex office to discuss in more detail.
