Andrii, Thank you for your previous mail. I am sorry for taking so long to answer. The rest of the mail is inline 2019年1月22日(火) 18:00 Andrii Anisov <andrii.anisov@xxxxxxxxx>:
I was able to compile the Xen image with earlyprintk without issue. It is comforting to get some sort of feedback from the device, even if it is failing. But I'm 99 percents sure you will see memory initialization error from XEN, so you should merge your memory nodes. I was also able to make a compilable DTB file by merging the memory ranges. I used the following configuration: memory@48000000 { device_type = "memory"; /* first 128MB is reserved for secure area. */ reg = <0x0 0x48000000 0x0 0x38000000>, <0x6 0x00000000 0x0 0x40000000>; } > > That my M3 is old sounds unfortunate. -- When attempting to boot the Xen image created I did get print messages but I get the following: [ 0.000191] NOTICE: BL2: R-Car Gen3 Initial Program Loader(CA57) Rev.1.0.21 [ 0.005753] NOTICE: BL2: PRR is R-Car M3 Ver.1.0 [ 0.010422] NOTICE: BL2: Board is Starter Kit Rev.1.0 [ 0.015534] NOTICE: BL2: Boot device is HyperFlash(80MHz) [ 0.020960] NOTICE: BL2: LCM state is CM [ 0.025002] NOTICE: BL2: AVS setting succeeded.

As I mentioned before I am using the rocko branches from meta-virtualization and meta-selinux as shown below: Build Configuration: BB_VERSION = "1.36.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "universal-4.9" TARGET_SYS = "aarch64-poky-linux" MACHINE = "m3ulcb" DISTRO = "poky" DISTRO_VERSION = "2.4.2" TUNE_FEATURES = "aarch64 cortexa57-cortexa53" TARGET_FPU = "" SOC_FAMILY = "rcar-gen3:r8a7796" meta meta-poky meta-yocto-bsp = "tmp:342fbd6a3e57021c8e28b124b3adb241936f3d9d" meta-rcar-gen3 = "tmp:fd078b6ece537d986852cb827bd21e022a797b2f" meta-optee = "tmp:75dfb67bbb14a70cd47afda9726e2e1c76731885" meta-oe meta-python meta-networking = "tmp:dacfa2b1920e285531bec55cd2f08743390aaf57" meta-selinux = "rocko:d855c624f32c5e599bf27e06cb8f5b25b3aae12d" meta-virtualization = "rocko:b704c689b67639214b9568a3d62e82df27e9434f" meta-rcar-gen3-xen = "lastest_xen:cc6e6e1c07197207769331b0532fc88a9165a855" I have no idea if that affects the u-boot creation, but I thought I might as well mention that. Once again thank you for all the help. If there is any other information I can give you, please let me know.
