OK, that indicates an issue with the serial port rather than anything to do with the dom0 configuration. I'm going to assume this isn't a h/w issue and that you've tested the serial port works e.g. with native Linux? It could also be a RTS/CTS misconfiguration between Xen and the host terminal emulator, I suppose, so that's worth checking. Otherwise it seems like the issue is either with the Xen serial port driver for your platform or with the DTB description of hte IRQ or something like that. J6 EVM is an Omap5, right? With the same UART as people have reported successes with on other OMAP5 platforms e.g. at http://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/OMAP5432_uEVM ? Please could you post a full serial log of the boot, perhaps that will give us a clue. Ian.
