About FreeRTOS for BeagleBone Black
BBBFreeRTOS is a port of the FreeRTOS real-time operating system for the BeagleBone Black single-board computer. The repository includes a Makefile located in Demo/AM3359_BeagleBone_GCC/ along with working MLO and u-boot bootloaders (stage 1 and 2). The port currently has working system tick, interrupt handling, and GPIO output. Serial input is noted as not yet finished. A test main.c file demonstrates setting up GPIO interrupts on three input pins and responding on three output pins. The implementation relies on the AM335x technical reference manual for register configuration.
