Hi All,
I'm using QorlQ LS1043A RDB and following Yocto distribution:
BB_VERSION = "1.32.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "universal"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "ls1043ardb"
DISTRO = "poky"
DISTRO_VERSION = "2.2.1"
TUNE_FEATURES = "aarch64"
The problem is, that I can not get PCIe to get working. I receive following error, once linux starts up:
root@ls1043ardb:~# dmesg | grep pci

I can't figure out, why msi controller can not be found.
Any help would be appreciated.
