Hi Stefan. Thanks for your answer. I though NPe405H was supported by u-boot. Anyway. Yes, I enable the pci debug, I saw the Pci Autoconfig messages (Mem and I/O adrresses), but when u-boot scan the bus, to find any device, it stops in those functions. I am using BDI2000, but unfortunatelly I do not have the bdiGDB package. We will buy it as soon as possible. So I have no way to configure PCI interface by hand. Could you explain me how it is made PCI bus scan? Basically the function pci_hose_read_config_byte(). How it is read the HEADER_TYPE for example, is it made by I2C or data bus, acessing direct processor registers? Regards.

Not that I am aware of. No NPe405x support has been published officially.

Basically, the problem happens when u-boot tries to scan the bus. Function pci_hose_scan_bus tries to read a byte (Header Type) and a

word

(Vendor ID) but it does not return anymore from this function. Can anyone help me.

Not easy with that amount of information. Did you enable the debug output in the pci code? Did you try to do a pci config cycle by hand?

Best regards, Stefan
