Hi, I am trying to compile seL4 for the BBB. I am getting the following errors when it gets to timer_service. I am following the instructions at https://github.com/seL4/refos-manifest. I got past another compile error by adding a typedef to device_timer.h for pstimer_t. Any help is appreciated. // tfp, added to avoid compiler error typedef uint32_t pstimer_t; [apps/timer_server] building...
