since wifi stops problem experienced in 802.11s mode (see my previous post) I ended to port Darius carambola2 support to openwrt attitude_adjustment. Toolchain compiles and produces the openwrt-ar71xx-generic-carambola2-squashfs-sysupgrade.bin image.
The image size is around 15MB (15131482) and before flash my board I'm wondering if that size is right... since I do not want to brick my carambola
Waiting for your answers.
Thanks
