Re: Configuring network after fresh boot to lime2

[Sagar Acharya <sagaracharya%tutanota.com@localhost>]

I'd like to bring your attention to the recent change of u-boot since 2022.04 from rgmii to rgmii-id configuration. That may pose problems, I guess.

Thanking you

>> It for sure isn't an issue of the cable. No worries there. I'm pretty sure it's the pin delay that has to be set in dtb. That has been documented. Is there some config file which helps me see which dtb will be used? I have mounted the 80MB first partition of the sd card on which I've flashed the image. It has boot.ini, config.txt and so on, and a bunch of binaries. bootarm.efi is also a binary. I was hoping to change the configuration to use dtb which I have created. How can I do that?
