Hi, Trying to run XEN on imx8mq which is different from imx8qm in term of UART controller IP(attached is the debug code).
DTS used for host is : https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_4.9.x_2.0.0_ga/arch/arm64/boot/dts/freescale/fsl-imx8mq.dtsi But , I see following issue: => setenv xen_addr_r 0x42000000 ;setenv fdt_addr_r 0x43000000;setenv kernel_addr_r 0x40480000 => setenv fdt_high 0xffffffff;fdt addr $fdt_addr_r;fdt resize => setenv xen_bootargs console=dtuart dom0_mem=1024M => setenv dom0_bootargs console=hvc0,115200n8 earlycon=xenboot debug clk_ignore_unused root=/dev/mmcblk1p1 rw rootwait => fdt set /chosen xen,xen-bootargs \"$xen_bootargs\"; => fdt set /chosen xen,dom0-bootargs \"$dom0_bootargs\";fdt mknode /chosen modules => fdt set /chosen/modules '#address-cells' <1>;fdt set /chosen/modules '#size-cells' <1>;fdt mknode /chosen/modules module@0 => fdt set /chosen/modules/module@0 compatible "xen,linux-zimage" "xen,multiboot-module" => fdt set /chosen/modules/module@0 reg < $kernel_addr_r 0x1800000 > => => booti ${xen_addr_r} - ${fdt_addr_r} ## Flattened Device Tree blob at 43000000 Booting using the fdt blob at 0x43000000 reserving fdt memory region: addr=43000000 size=d000 Loading Device Tree to 00000000be510000, end 00000000be51ffff ...
