> ....PCIE link error. Skipping scan.LTSSM=0x08 The LTSSM value of 8 indicates the problem. See: "Table 18-111. PEX_LTSSM_STAT Status Codes" 8 - "Polling compliance" This shows the 8536 is fine and detects the device's receivers on the bus, but the device has not responded with a correct training sequence. There are many potential causes for the device not responding: 1. device powered on? 2. have correct clocks? 3. if an fpga, is it loaded? 4. is it out of reset? What is the device? Can you query it with a jtag probe? > PCIE1 on bus 01 - 01 > > I was expecting to find a peripherical on PCIE1 bus. I have a switch > chip connected to Serdes 1 lane A. I see. What switch?

You can read the ltssm register from the prompt and on a working link you will see 16: => pci d 1.0 404 1 00000404: 00000016 -Ed _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
