1、加载驱动命令
./load_driver.sh
打印如下：Loading driver...
Error: The Kernel module installed correctly, but no devices were recognized.

2、列举PCIe设备信息命令
lspci
打印如下：0000:00:00.0 PCI bridge: Fuzhou Rockchip Electronics Co., Ltd Device 3588 (rev 01)

按照log来说驱动加载并没有问题。只是没有识别到pcie设备 799959745 发表于 2022-6-27 14:32

以下是dmesg中的pci信息，怀疑是不是能够给其他PCIe设备分配的内存不够导致的。

pci 0000:01:00.0: BAR 2: no space for ，看这一句，主要是rk3588的pcie低端bar内存大小只有16MB，对端FPGA把内存配置减小就好了 请问您做的是itx 3588j和fpga板卡通过pcie互联嘛，我想咨询一下3588开发板的pcie的endpoint模式切换能不能实现，通过rk3588官方的修改dts就可以吗 wx__BkXu5u 发表于 2022-8-2 10:41

dts没有修改，主要是FPGA那边进行适配，你要看一下3588的dts文件，最大能支持多少的内存
