XIO2001 can't deassert PCIRST correctly.

Other Parts Discussed in Thread: XIO2001, PMP

Hi,

I have a app with the following configuration: TI DM8168 (pcie)---> XIO2001(pcie-pci-bridge) --> TI DM648,  but the XIO2001 can not deassert PCIRST after DM8168 finish the linux kernerl loading, Actually, the XIO2001 does deassert PCIRST in a very short time when dm8168 is loading its kernel, but around several mili-second, then assert the PCIRST again.  I also find the the LTSSM state changes from 0x11 --> 0x0d or 0x0f or 0x10,  which may mean it is in some recovery state.  not sure what is this meaning.  Here attached is the log from linux kernerl output of DM8168.   finally, the LTSSM goes to 0x1f.  I also checked the wave form of the Tx line of DM8168, which is the rx line of XIO2001, it also become idle ~40ms after it assert PCIRST again?   Any clues you can provide to me for further investigation?

you can find some LTSSM changes.

    Hello,

    You can do the folowing:

    1) Make sure you are following the Power-up sequence described on section 3.1.1 of datasheet.

    2) Review the Table 3-1 ( Reset Features), make sure you have the correct value on SRST bit.

    3) Check that the coupling caps on TXN/TXP are the correct value (0.1uF) and measure the resistance between REF0_PCIE and REF1_PCIE for the correct value (14532 ohms). Also check that GRST# is de-asserting after power is okay.

    Can you share your schematics and a Register Dump pf the bridge?

    Regards.

    Hi,

    1.  I follow the reference clock come out  first and after 100ms to release the PERST, the variance of LTSSM becomes better but still PCIRST goes to ground after several seconds before linux kernel finishs its loading.

    2. I can't touch the SRST bit in XIO2001, as the LTSSM becomes to 0x1f before the linux kernel finishs its loading.

    3. the TXN/TXP is 100nF, the reference resistor is ok, the GRST# is pullup through 10k to D3V3.

    4. I don't how to dump the register of xio2001, but the schematic is attached here.0825.NETRA_TEST_REV1_P40P41.pdf

    5.  I found that the differetial reference clock can't use ac coupling method, otherwise i can't get stable PCI clock. 

    overall, the situation is basically still the same, but it looks like the interval between "PCIRST is high" and "PCIRST goes to ground (asserted)" is very random. Sometimes the interval is 20s, sometime the interval is very short.  the waveform is like this:

      

     

    I have already remove the resistor of CLKRUN and EXT_ARB, they are float now, but according to datasheet, these two should have internal active pull down.

     

    Thanks,

    Ji Kai

    Hello,

    1) Please connect the GRST# terminal to the "Power_Good" signal coming from your PCIe host.

    2) You are enabling the external arbiter, is that what you really want? If not, please connect EXT_ARB_EN to ground.

    3) Leave VDD_33_AUX floating.

    4) Can your PCIe host detect and configure the XIO2001 even when this one is asserting the PCI Reset?

    Regards.

    Hi,

    I float the VDD_33_AUX and connect EXT_ARB_EN to ground, and find the 1v5 voltage doesnot reach to 1.5, it only has 1.44, so increase the 1.5v a bit, then it works.

    I think the 1.5V voltage might be cause for those unstable pcie connections.

    Thanks,

    JI Kai
