ECC not enabled on EVMK2H, DDR3 Initialization Application Note.

Lance Jump

It appears that DDR3 ECC is not enabled in the EVMK2H board BSP. Is there some reason for that?

We will be bringing up a custom board based on the K2H and I would like to enable ECC and see if there are any changes to DDR3 initialization based on our layout.

The document "DDR3 Initialization Application Note" for Keystone II is referenced in the "Keystone II Architecture DDR3 Memory Controller" (SPRUHN7A) and I have seen references to it on the forums, but I can't find it. Any idea where I can get it?

Thanks,

Lance

Lance,
The KeyStone II DDR3 Initialization Application Note has not been released yet. We expect to publish this early in January.
Please refer to the GEL file available for K2H that properly implements the configuration procedure.
The REG_CALC spreadsheet attached below will be supplied along with the Init App Note.

The latest GEL is available with the MCSDK at:
http://software-dl.ti.com/sdoemb/sdoemb_public_sw/mcsdk/latest/index_FDS.html
and the latest GEL is contained in the EMU PACK in that MCSDK page:

Tom,

Thanks -- that explains why I can't find the App Note. I look forward to seeing it. Meanwhile, the spreadsheet should be a great help.

Any thoughts as to why the EVMK2H BSP does not use ECC? The board appears to be equipped for it?

Thanks,
Lance

Lance,
ECC support is in the Linux uboot that is currently available in MCSDK. This was not fully supported until PG2.0 K2H devices became available. Please refer to: http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Exploring#DDR3_ECC.

Tom,

Okay, that explains it. This might be the impetus I need to move from MCSDK 3.0.3.15 to the latest (3.1.1.4).

Thanks,
Lance

Tom,

Is there any word on when the Keystone II DDR3 Initialization Application Note will be released? The latest DDR3 User's Guide (January, 2015) refers to it?

As an aside, I upgraded to the latest MCSDK and now have ECC on the EVM. My next task is to port the DDR3 initialization to my custom hardware, which does use the same memory device.

Thanks,

Lance

Lance,

It is on the product pages under the Application Notes heading and the direct link is http://www.ti.com/lit/pdf/sprabx7.

Let us know if you need more help with the ECC.
