======
This README discusses issues unique to NuttX configurations for Motorola
MDK.
STM32L476ME:
Microprocessor: 32-bit ARM Cortex M4 at 80MHz STM32L476ME
Memory: 1024 KB Flash and 96+32 KB SRAM

Flashing:
The MDK has a builtin FTDI to support flashing from openocd. There are a few extensions
to openocd that haven't been integrated upstream yet. To flash (or debug) the MDK, you
will need the code from:
git clone https://github.com/MotorolaMobilityLLC/openocd
After building, you can flash with the following command:
openocd -f board/moto_mdk_muc.cfg -c "program nuttx.bin 0x08000000 reset exit"
