[U-Boot] PCIe on Kilauea

[U-Boot] PCIe on Kilauea

[Weirich, Bernhard]

Hi!

I have installed u-boot v-2009.06-rc1 on my kilauea board (using BDI2000).

It boots but it stalls at line 716 in 4xx_pcie.c
Even when I plug in a PCIe card it does not get any further.
Are there any known issues with PCIe on the kilauea eval board?
Am I doing anything wrong (although I cannot imagine what

4xx_pcie.c:
/* poll for phy !reset */
 716         while (!(SDR_READ(SDRN_PESDR_PHYSTA(port)) & 0x00001000))
 717                 ;

Thanks,

Best regards,
Bernhard

No, not that I remember.

The only idea I have is power supply. Are you using an ATX power supply? This 
is mandatory for PCIe IIRC. Other than this I have never heard of a board 
hanging in PCIe init without any card installed. Perhaps it's a HW problem on 
the board.

BTW: Did you test with an earlier U-Boot version? How did this work?

Best regards,
Stefan

Thanks for the prompt reply!
It was indeed a hardware problem. The calibration resistor was missing.
