TDA4VM: linux 3.2.2.11. PCIe Backplane test error

Thomas Yang
Prodigy 100 points
Part Number: TDA4VM

Hi TI Team:

We test pcie Backplane use 3.2.2.11. PCIe Backplane — Processor SDK Linux for J721e Documentation.

the test SDK is 8.0

at ep side we config:

root@j7-evm:~# ls
ntb_test.sh
root@j7-evm:~# cat ntb_test.sh
#!/bin/sh
cd /sys/kernel/config/pci_ep/
mkdir functions/pci_epf_ntb/func1
echo 0x104c > functions/pci_epf_ntb/func1/vendorid
echo 0xbd01 > functions/pci_epf_ntb/func1/deviceid
mkdir functions/pci_epf_ntb/func1/pci_epf_ntb.0/
echo 4 > functions/pci_epf_ntb/func1/pci_epf_ntb.0/db_count
echo 128 > functions/pci_epf_ntb/func1/pci_epf_ntb.0/spad_count
echo 2 > functions/pci_epf_ntb/func1/pci_epf_ntb.0/num_mws
echo 0x100000 > functions/pci_epf_ntb/func1/pci_epf_ntb.0/mw1
echo 0x100000 > functions/pci_epf_ntb/func1/pci_epf_ntb.0/mw2
ln -s controllers/2900000.pcie-ep/ functions/pci_epf_ntb/func1/primary
ln -s controllers/2910000.pcie-ep/ functions/pci_epf_ntb/func1/secondary
echo 1 > controllers/2900000.pcie-ep/start
echo 1 > controllers/2910000.pcie-ep/start
root@j7-evm:~#

but when we start up rc side EVM , the error occurred。 the error log is follow:

    Thomas, 

    Not sure if progress has been made on this test. It seems the EL1 exception was caused by access to one of PCIE address. This is typically caused by boot up sequence of the boards. please reply back if the issues still exists.
