PCIe initialization error

Postby Guest »

thanks so much for PCIe article.
I was trying to debug a failure when the server bios was (tried on PC - same ) not able to initialize the GPU card hence it stuck on boot.
I was wondering to understand the initialization process to see what is wrong with the GPU.
As per BIOS POST code it is PCI device initialization failed.
I see the bus also have JTAG lines. what you sugest to troubleshoot this error.
I checked 12V exist on the bus.
Should i check SMUBUS activity next?
Say power sequencing like POR is working (12V -> PG ->Pow_EN->Reset(deassert))
Thanks in advance
