Ticket Name: Linux/TDA2: TDA2xx support for PCIe EP Linux driver.
Query Text:
Part Number: TDA2 Tool/software: Linux Hi, We are using two TDA2xx evms for PCI interface integration between two boards. This the link which we followed http://processors.wiki.ti.com/index.php/Linux_Core_PCIe_EP_User%27s_Guide For the endpoint device we got error like below. How to resolve this error in endpoint controller device? The kernel log is shown below:- [ 0.599817] ---[ end trace 89b6ef26cae49ac5 ]--- [ 0.599829] dra7-pcie 51000000.pcie_ep: pm_runtime_get_sync failed [ 0.599857] dra7-pcie: probe of 51000000.pcie_ep failed with error -22 We are using PROCESSOR_SDK_VISION_03_04_00_00
Responses:
Hi Sreerag, I have pinged an expert to comment. Regards, Yordan
Hi have you made the required Device tree modifications to configure on of the boards in Endpoint mode. Can you attach the full boot up log and brief summary of changes carried out
attached the code changes and kernel log. changes.diff diff --git a/ti_components/os_tools/linux/kernel/omap/.config b/ti_components/os_tools/linux/kernel/omap/.config

RC dt node should be disabled in order to enable EP . Instead of changing dra7-evm.dts, please try changing dra7-evm-common.dtsi. In dra7-evm-common.dtsi, replace &pcie1_rc with &pcie1_ep Thanks Kishon
