What have you tried and looked at that was not enough information? And what do you mean exactly by "BSP"? What exactly are you trying to do?

Again "linux" is the kernel, and Android is only the userspace stuff on top of that. They are independent, you can run "Android" on a desktop just fine. Take look at the Android documentation for how to set this all up, there are loads of resources online for this. good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies ^ permalink raw reply [flat|nested] 9+ messages in thread
