PCIe[edit | edit source]
Description[edit | edit source]
The two PCI Express lines are available on the Evaluation Kit at the connector J15 and J18.
- J15 is a standard M.2 connnector dedicated to the WiFi module
- J18 is a standard 36 contacts female PCIe connector for a card edge PCIe module
Signals[edit | edit source]
Both connector interface signals respect the related M.2 and PCIe standards. The interfaces signals mapping can be found in the Evaluation Kit schematics.
Device mapping[edit | edit source]
The PCI express peripheral is mapped to the corresponding device in Linux depending on the associated kernel device driver and on the device tree configuration.
