I can confirm that sending/receiving on UART5 is working. Unfortunately I don't have a HDMI display here to test it.
To ensure that the HDMI is disabled, I have deleted /lib/firmware/cape-boneblack-hdmi* and removed all entries for HDMI from am335x-boneblack.dts. I have now all 6 uarts working (except for uart3 that can only do tx). Now I'm trying to use uart0 via P9.
