Hi TI,
following the instructions given in http://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/PCIe/PCIe_End_Point.html I
managed to run pcitest.sh successfully with 1 physical function added. However, if I try to add more than one physical function to the same endpoing device, I get the following errors when booting up RC side:

This log was created, when I tried to add 2 physical functions. The command to add these functions on EP side was:
mount -t configfs none /sys/kernel/config cd /sys/kernel/config/pci_ep/ mkdir functions/pci_epf_test/func1 echo 0x104c > functions/pci_epf_test/func1/vendorid echo 0xb00d > functions/pci_epf_test/func1/deviceid echo 2 > functions/pci_epf_test/func1/msi_interrupts echo 2 > functions/pci_epf_test/func1/msix_interrupts ln -s functions/pci_epf_test/func1 controllers/d000000.pcie-ep/ mkdir functions/pci_epf_test/func2 echo 0x104c > functions/pci_epf_test/func2/vendorid echo 0xb00d > functions/pci_epf_test/func2/deviceid echo 2 > functions/pci_epf_test/func2/msi_interrupts echo 2 > functions/pci_epf_test/func2/msix_interrupts ln -s functions/pci_epf_test/func2 controllers/d000000.pcie-ep/ echo 1 > controllers/d000000.pcie-ep/start
Do you know what might be the problem here?
Thank you!
