[U-Boot-Users] Help with PCI using NPe405H
Hi everybody. I am having some problems to configure PCI interfcace in the NPe405H processor. Have anyone already ported u-boot to it? 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. Regards

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

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
