TMS320C6678: PCIe on C6678

VineyK

Part Number: TMS320C6678

Hi,

I'm looking through the PCIe example project that was provided along with the pdk installation, and I noticed this constant "pcie_MAX_PERIPHERALS" being set to 4. Could someone explain what that constant means?

Thanks,

Viney

Hi Viney,

I've forwarded this to the c66x PCIe experts. Their feedback should be posted here.

Hi,

The PCIE LLD is used across for all Keystone I/II and Sitara devices. The pcie_MAX_PERIPHS is a place holder for maximum PCIE pheriphrals supported in the LLD. Some device may have 2 PCIE interfaces, or more in the future. We just use it to avoid adding it over time. For C6678, there is only 1 PCIE interface.

Regards, Eric
