evm-sdk8.0 的Linux,启动后无法识别 USB 总线。

Other Parts Discussed in Thread: AM3358

如题:

我们的板卡参考了 EVM 板,使用的芯片是 AM3358。需要配置电源芯片/正确的主频之后正常启动之后。

从官网下载的 evm-sdk8.0 , 使用 create_sd.sh 制作的启动盘(使用ti-sdk 默认的 kernel (/boot/zImage)) , 能够识别USB总线和设备。

在此基础上,使用 evm-sdk8.0 中 board_support/linux3.14.26-xxxx/ 编译 kernel ,使用 singlecore-omap2plusdefconfig 配置,编译出的KERNEL无法识别 USB 总线/设备。devicetree 使用的是 am335x-evmsk.dts 。下面会描述 .config 文件以及 启动 log。

 项目比较急,麻烦了!!!任何回复都非常感谢。先在此谢过。

 * 尾部有lsusb的打印,以及 /proc/bus/目录下没有usb,且 /proc/driver/ 下也没有usb总线相关的节点。

.config 关于USB 部分(其中我发现make 后面加上配置名字,会默认先覆盖.config文件):
