I have designed a TX2i carrier board, and contain an Intel IC 82599ES. But, TX2i can’t link the network IC, there is nothing when I printed ‘lspci’.
Electrical connections: TX2i PCIEx4 (PEX0/USB_SS1/PEX2/PEX_RFU,PEX0_REFCLK,PEX0_RST,PEX_WAKE) — 82599 (PCIEx8 lane0-3,PE_CLK,PE_RSTn,PE_WAKEn)
On the hardware, I have done some tests:
I have saw the PCIE enumeration process (‘PCIE RST’ pulled high, ‘REFCLK’ 100MHz CLK ) on the oscilloscope.
I have connected the 82599 circuit to another X86 CPU, and it linked. (Fly line test contain all the PCIE signals, the following tests all the same)
I have connected the TX2i PCIE signals to the I210 device, and it linked. (Fly line test)
I have connected the TX2i PCIE signals to another 82599 circuit, and it dosen’t linked. (Fly line test)
And I have another TX2i carrier board, PCIEx1 connected an Intel IC 82580, it worked.
Now I have no idea on the hardware, anyone knows what can I do next?
And please give some advice on the software. Thanks!
