RM500U-CNV PCIE 无法正常通信

[zhang1990xue]

pcie设备应该识别到了：
root@RK3588-Tronlong:/sys/bus/pci# lspci
0003:30:00.0 PCI bridge: Fuzhou Rockchip Electronics Co., Ltd Device 3588 (rev 01)
0003:31:00.0 Wireless controller: Synopsys, Inc. DWC_usb3 / PCIe bridge (rev 01)
但是还是打不开设备
root@RK3588-Tronlong:/sys/bus/pci#
root@RK3588-Tronlong:/sys/bus/pci# cat /dev/stty_nr31
[58350.295915] spipe 1-6 not ready to open!
cat: /dev/stty_nr31: No such device
查看启动log，这个通道的open没有成功：root@RK3588-Tronlong:/sys/bus/pci# dmesg | grep sms

请问大概是何种原因？谢谢！
