I am trying to enable uart4 and uart8 on colibri-imx6ull module.
Here is my dtb customization: link text .
After flashing the dtb /dev/ttymxc7 is present but I can’t see /dev/ttymxc3 (that should correspond to uart4.
Are there something related to pinmux problem reported here: link text ?
Thank you for the support,
