Hi @Michielt ,
thanks for the clarification. I understand the situation better now.
I am looking into this, in the meantime. Have you seen the following community post?
https://community.toradex.com/t/device-tree-for-uart-in-dce-mode-for-imx6ull-module/8569
I recommend you give this a read if you haven’t yet, it’s not the same module you use, but the method might work on your end too. Some changes in the u-boot section can temporary fix the issue, and then there’s some information on how to make the change permanent.
I will keep you updated for further information as soon as I gather them.
Best Regards
Kevin
