AP6236wifi驱动加载问题

hydys

按照官网操作修改buildroot/configs/firefly_rk3308_release_defconfig，开启BR2_PACKAGE_RKWIFIBT_AP6236，执行ifconfig  wlan0 up操作发现：
[  146.039152] DHD: dongle ram size is set to 524288(orig 524288) at 0x0

看log驱动固件都没有找到，请问有没有完整教程，还是我的操作出了问题？

1. 开发板型号是什么，编译步骤是什么
2. ROC-RK3308-CC和ROC-RK3308B-CC是不同的wifi模块的，编译方式也不一样的， 详细编译过程见维基教程
3. buildroot有修改，建议删除buildroot/output目录后再编译
