Dear all,

i’m working with the following configuration:
Apalis iMX8QM 4GB WB IT V1.1D
Ixora Carrier Board V 1.2A
Linux BSP 6.3.0

I want to improve to enable firmware load through PCIe.
When I try to run the PCIe-driver, I get the following error on the MSI interrupt:

Can someone help me with this, pls?

The default u-boot passes nomsi to pcie driver.

Apalis iMX8 # print defargs
defargs=pci=nomsi

You can delete it by the following command in u-boot.

Apalis iMX8 # setenv defargs
Apalis iMX8 # saveenv
Apalis iMX8 # reset
