Because NXP MPU's regions are dynamically enabled/disabled, USB device's access maybe restricted when switching out of a task. Background DMA transfers to/from RAM may happen during MPU region reconfiguration or core idling. Enabled USB (Kinetis MPU Master 4) to always have access to RAM address space.

Notes on the FSL FRDM K64F SRAM base address and size Although the K64F CPU has 64 kB of SRAM at 0x1FFF0000 (code space), it is not used by the FSL FRDM K64F platform. Only the 192 kB region based at the standard ARMv7-M SRAM base address of 0x20000000 is supported. As such the following values are used: CONFIG_SRAM_BASE_ADDRESS=0x20000000 CONFIG_SRAM_SIZE=64 # Measured in kB
