Hi,
I am Abinaya's colleague from Belden Inc. Abinaya was working on the following issue.
We have resolved the above issue. But another related issue is being seen.
In the above block diagram Broadcom switch (BCM56340) in PCIe domain-2 does not get detected during boot (warm boot/reboot). This happens 50% of the time. It fails to get detected roughly 5 times out of 10 times. While scanning bus no. 0 (primary bus), PCIe-PCIe bridge gets detected, but when bus no. 1 (secondary bus) is scanned, it fails to detect BCM56340 randomly. Once it fails to detect BCM56340, the system throws the following error messages:
[ 0.673219] omap_l3_noc 44000000.ocp: L3 application error: target 5 mod:1 (unclearable)
[ 0.673235] omap_l3_noc 44000000.ocp: L3 debug error: target 5 mod:1 (unclearable)
My queries are:
1) Let us know what is going wrong. What is the problem?
2) Why is BCM56340 connected to PCIe domain-2 not getting detected consistently?
3) Let us know whether it is a problem with the PCIe-PCIe bridge of Dragon AM572x or with Broadcom switch BCM56340.
4) What should be done to resolve this issue?
5) Why are the following error messages thrown?
0.673219] omap_l3_noc 44000000.ocp: L3 application error: target 5 mod:1 (unclearable)
[ 0.673235] omap_l3_noc 44000000.ocp: L3 debug error: target 5 mod:1 (unclearable)
Note that there is no such problem with PCIe domain-1. BCM56340 in PCIe domain-1 always gets detected.
Here are the function call trace/logs of PCIe subsystem in success and failure cases:
