Macro Definition Documentation

◆ BCM2835_EMMC_BASE

#define BCM2835_EMMC_BASE (RPI_PERIPHERAL_BASE + 0x300000)

NOTE: Since the SD controller follows the SDHCI standard, the rtems-libbsd tree already provides the remaining registers.

◆ BCM2835_GPU_TIMER_BASE

#define BCM2835_GPU_TIMER_BASE (RPI_PERIPHERAL_BASE + 0x3000)

NOTE: The GPU uses Compare registers 0 and 2 for it's own RTOS. 1 and 3 are available for use in RTEMS.
