Part Number: AM5728

Customer reporting unexplained ERR_AXI interrupt event. They would like to better understand:

1. Possible cause for this

2. Any recommendation to recover from this error without rebooting? Such as reset PCIe interface?

Please post what software are you using - Linux or RTOS? Which version?

They are using Linux kernel 4.4.84

Hi Lawrence,

Sorry for the late response.

Can you please ask the customer to provide the log of command 'lspci -vv' on the AM5728 Linux console?

Customer does not know the root cause yet why it happens.

To easily simulate the issue, they intentionally started an application called CPSS twice at same time to capture logs.

It maps PCIe resource for user space application and causes AXI error in seconds.

Please note customer does not run 2 instance at same time for production. Even there is only 1 application running, they observed the AXI error.

Sometime, they also observe ERR_FATAL or ERR_NONFATAL. But eventually, the driver detects ERR_AXI.

Here is an example of log.

Hi Lawrence,

Can you please confirm if the customer uses both kernel and filesystem from the Processor SDK Linux v3.x release? The log seems indicating it is not the case.

What is the PCIe device plugged in?

Can the customer test with the latest Processor SDK release to see if the issue can be reproduced?

With PLSDK v5.03, I expect to see the PCIe RC name as following,

root@am57xx-evm:~# uname -a
Linux am57xx-evm 4.14.79-ge669d52447 #1 SMP PREEMPT Sat Apr 6 02:23:36 UTC 2019 armv7l GNU/Linux
root@am57xx-evm:~# lspci
00:00.0 PCI bridge: Texas Instruments Device 8888 (rev 01)

but the log you provided shows

# lspci -xxx -vv
00:00.0 Class 0604: Device 104c:8888 (rev 01)

so I am not sure if the customer uses the kernel and rootfs from the PLSDK release.
