PCIe EDAC errors on P4080 ?

[stevereynolds]

Hi

On our P4080 board using SDK 1.5 I see these errors at boot but then everything seems to work OK. There are reports of this on various forums but I cannot see a fix

Does anyone else see these ? See the line which says PCIE Error(s) detected

Thanks

Steve

Hello Steve,

This is hint information not error message, actually this has already been addressed in the SDK 1.6 document.

If EDAC Kernel module is loaded, there is Kernel boot message as the following.

OK Thanks for answering, but it looks from your reply as if on 1.6 the error is only printed once as a test, but I see it over and over?

Is the 1.6 code different in this area or is just the documentation different?

Should I move to 1.6 more quickly than I had intended to? or should I ignore these errors ?

Thanks again

Steve

This looks like PCI is scanning the bus.

As PCIE ERR_DR register: 0x00020000 it's Invalid CONFIG_ADDR/PEX_CONFIG_DATA access

PCIE ERR_CAP_STAT register: 0x80000001 also shows Transaction originated from PEX_CONFIG_ADDR/PEX_CONFIG_DATA

PCIE ERR_CAP_R0 register: 0x00000800 it's PCI Express type 2, format 0

Hello Steve,

I think you could ignore these messages, it will appear in Kernel boot log, if EDAC is enabled.

CONFIG_EDAC_MM_EDAC

CONFIG_EDAC_MPC85XX

These options are enabled in the default Kernel config file, please refer to the following log which I captured with SDK 1.6 pre-built images.
