您好，
根据链接调试 PCIe 的驱动程序时、我发现 PSDK7.0以下的相应版本不能用于内核5.4.40
http://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/PCIe/PCIe_End_Point.html
是否有 PSDK7.0内核5.4.40？的补丁

您好、Hubing、 要为 PCIe 实例启用 PCIe_EP、请从 pcieX_EP 中删除 status ="disabled"标志、并将该标志添加到 pcieX_RC 中。 例如：执行以下更改以在 EP 模式下启用 pcie0。
diff -git a/arch/arm64/boot/dts/ti/k3-j721e-common-proc-board.dts b/arch/arm64/boot/dts/ti/k3-j721e-common-proc-board.dts index 6788a3611..b7cd6c7b6 100-trs/ge-board/common-tr-s/gm/ds-7+-trs/gm/ds-7+-trs/gm/dts–tr-gm/gm/gm/gm/gm/gm/gm/ds-b/spr-tr-gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/gm/ds-b/soti+-gm/gm/gm/gm/gm/gm/ds-b @@@@ phys =<&serdes0_PCIe_link>； PHY-names ="PCIe_phy"； 通道数=<1>； + @@="禁用"；｝；&pcie1_RC｛@@-833,7 +834,6 μ s phys =<&serdes0_PCIe_link>； PHY-names ="PCIe_phy"； 通道数=<1>； - 状态="禁用"； ｝； &pcie1_EP｛
