hello,xilinx engineer!

     

     Recently i was debug the SATA OOB 8B/10B decoding err problem on kintex7 device, i generate the gtx for sata2.0 spec,

I choose the " RX EQUALIZER, clock correction, rxslide mode pcs, FIX RX_CDF_CFG"32'h03_8000_8bff_4020_0008",   dfe auto mode ,rx trim volatage 800mv" options, BUT when debug the kintex7 evaluation kit (KC705) + hightechglobal fmc sata board function, I FOUND that , the sata oob is not stable, THE signal "rxnotintable " often occur.

PLEASE GIVE ME SOME SUGGECTION!

I had solved the problem!

User should manual config the GTX parameter for sata spec! The main factor is CDR, CLOCK CORRECTION, rx equalizer;

I had test many SSD with my SATA host controller ,DMA read and write speed is about 240MB/S;

my host controller can work stability for long long time!

Any one who workaround the satahost can contact me!

Hi,

 

    Can you please tell if you have solved your problem?

 

What should be the value of RX_CDR_CFG for SATA3?

And what should be the value of RX_DFE_XYD_CFG?

 

With Regards:

Ahsan

Hi mrwanghl,

 

I need your help. we are debugging SATA. 1.5G is ok. however we find 8/10b error when it is 3G. We change RXCDR_CFG to 72'h03_8800_8BFF_4020_0008. the issue still can not be fixed.

GTX setting: 16 bit data/enable 8/10b/CPLL/auto DFE.

could you help to provide some data to us? my email is 175489501@qq.com

Hi,

 

I have some problems on SATA 3Gbps. I sometimes get RXELECIDLE and RXNOTINTABLE indications at some long transfers.

Can this be about settings ? I use GTX Transceiver Wizard 3.4 on 2014.4. ?

 

Thanks.
