Hello all.

I am writing in reference to the post

I'm using yocto / toaster to build a system image.


In the directory /boot
I have such drivers:

After setting in u-boot:
setenv fdt_file imx7d-sdb.dtb
I have access to the network but I do not have access to epdc.

After choosing:
setenv fdt_file imx7d-sdb.dtb
vice versa. Epdc works but network does not work.

I found google content in the file
Imx7d-sdb-epdc.dtsi in which i see
"Disabled" status on network interfaces.

Where can I find the file imx7d-sdb-epdc.dtsi in my yocto project
So that I could edit this file before building the system
And enable network support.

For help thank you in advance.
