JETPACK 6.2.2
JETSON ORIN NANO
手册上表示PCIE0_CLK_N/P会产生对应的时钟信号输出,但是通过示波器却没有测到相应信号;
手册上说明需要开启SF_PCIE10_CLK(GP21),但我在dtsi文件中没有找到相关的配置
请问具体如何配置,谢谢!
示波器上在jetson开启时有信号输出,但是系统完整开启输入用户名与密码后就没有信号输出了
Please check PCIe tuning guide. There is patch to disable power down function in the driver code.
In brief, if the pcie controller is not able to enumerate your PCIe device, power down function would happen to disable PCIe controller.
