PCIe1 issue on T4160RDB-64B

[vinothkumars]

Dear  NXP friends,

I am working PCI interface on T4160RDB-64B machine.  I got no link for PCIe1 and I checked everything in RCW.

PLL1 only we used and PLL2 not used

Using SERDES1 Protocol: 27 (0x1b)
Using SERDES2 Protocol: 55 (0x37)
Using SERDES3 Protocol: 5 (0x5)
Using SERDES4 Protocol: 9 (0x9)

PCIe1: Root Complex, no link, regs @ 0xfe240000
PCIe1: Bus 00 - 00
PCIe2: disabled
PCIe3: disabled
PCIe4: Root Complex, x1 gen1, regs @ 0xfe270000
02:00.0 - 126f:0750 - Display controller
PCIe4: Bus 01 - 02

what could be the issue? need to done any configuration in u-boot side.

1) Please provide as text attachment complete U-Boot booting log

2) Which EP device is used?

3) Into which RDB slot it is installed?

Hi Ufedor,

Thank you for your reply, and also I attached the log for your reference.

Why in the provided log:

Board: T4160RDB, Board rev: 0x00 CPLD ver: 0x0000, vBank: 0

What is this "T4160RDB"?

[vinothkumars]

Hi Ufedor,

Our board is T4160RDB

CPLD is current bank and board revision is 0

Fine.

Then you have to provide additional information:

1) complete processor connection schematics as searchable PDF

2) measured frequencies of all SerDes reference clocks

3) Which EP device is used?

4) How the EP device is connected?

2) measured frequencies of all SerDes reference clocks

3) Which EP device is used?

4) How the EP device is connected?

[vinothkumars]

Hi Ufedor,

Serdes1 Frequency -  100MHz

Serdes2 Frequency - 156.25MHz

Serdes3 Frequency - 100MHz

Serdes4 Frequency - 100MHZ

EP device is PCI switch

Required additional information:

1) complete processor connection schematics as searchable PDF to check PCIe connection and SerDes powering

5) read the PEX control/status register 0 (CSR0) several times and provide values
