Hi all,
We have been working on getting Xen hypervisor up on TI DRA7xx J6 platform. We are using 4.4 kernel version (It is supported by TI's Processor SDK). We are able to get upto kernel boot but having issues getting serial console shell login. We are able to switch between dom0 and xen console. Also able to dump logs through 'w', 'e', 't', 'h' etc.. from xen console. We have cross compiled xen tools, enabled systemd support and copied the binaries and serives to their respective location in the rootfs. Problem is with getting login shell. We are using USB to serial cable which comes along with J6 evm board. We have enabled CONFIG_LL_DEBUG and CONFIG_EARLY_PRINTK Following is the boot logs : U-Boot 2014.07-00035-gdcde330-dirty (Nov 17 2017 - 23:38:38) CPU : DRA752 ES1.0 Board: DRA7xx I2C: ready DRAM: 1.5 GiB WARNING: Caches not enabled MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 Using default environment SATA link 0 timeout.
