stressapptest error on ls2084a

[QiujuYe]

Hi FAEs,

I use stressapptest tool to test memory on LS2084a, but have errors, then I use EDAC to show, there is no ecc errors, the log is as followings, please give some advice to me, thanks very much.

I had the same problem

[yipingwang]

Have you used QCVS DDRv tool to connect to your custom board to do optimization and validation to get the optimized DDR controller configuration parameters?

[QiujuYe]

Hi yipingwang,

Thanks for you replay. yes, we use QCVS DDRv too to test, the result seems good and some parametes are adjusted, but still have errors. I am confused why stressapptest tool test failed but EDAC can not capature the ecc errors. and wthether we can from the fail addresses to get the real physical addresses, all the error bit is bit 44, is a single bit, why ECC_FIX_EN bit can not correct?

Do you use Rev 1.0 or Rev 1.1 processor.

It seems that you didn't  implement A-010679, the impact is as what you described.

A-010679: RCW[7] must be set to 1

Affects: GEN

Description: RCW[7] is a reserved bit and it should normally be cleared to 0. However, this bit has to be set to 1.

Impact: Data corruption could be observed if the workaround is not implemented.

Workaround: RCW[7] must be set to 1.

Fix plan: Fixed in Rev 1.1

[QiujuYe]

hi yipingwang,

Thanks for your reply.  I use lsdk1812 to build image,  I am not clear what you mean, where to find A-010679 and Rev 1.0 or Rev 1.1 processor?  can you explain clearly, thanks very much.

Best Regards

Would you please provide your u-boot console log?
