LS1043ARDB PCIe, msi controller not found

alesmulej — Thu, 13 Apr 2017 11:31:28 GMT

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.

Regards,

Hi,

thank you for your fast reply.

I downloaded SDK via following command: repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b morty

I'm using following linux version:

Linux version 4.1.30-rt34+g4004071 (alesm@ubuntu) (gcc version 6.2.0 (GCC) ) #3 SMP Thu Apr 13 11:58:44 CEST 2017
