itx-3588j buildroot启动后无wlan网卡设备

yf13

下载Linux SDK后，依据`README-IMPORTANT.md`做升级。升级后，(cd kernel ； git tag) 命令显示最后一行为`rk3588/linux_release_v1.0.1b`

然后选择【itx-3588j-buildroot.mk】编译后烧写并启动，以minicom访问串口后检查并收集附件的dmesg日志。

ifconfig里看不到wlan0.

在重新编译的Kernel上又做了试验：

貌似是没有检测到PCI总线上的Wifi网卡？尝试检查dmesg里有关pci的信息：

你好，我也遇到了相同的问题，请问这个问题你最终是怎么解决的啊？
