This port uses the [MAX32630FTHR ARM Cortex M4F Board](https://www.maximintegrated.com/en/products/digital/microcontrollers/MAX32630FTHR.html) with the onboard TI CC2564B Bluetooth controller. It usually comes with the [DAPLINK Programming Adapter](https://developer.mbed.org/teams/MaximIntegrated/wiki/MAXREFDES100HDK).
The DAPLINK allows to upload firmware via a virtual mass storage device (like mbed), provides a virtual COM port for a console, and enables debugging via the SWD interface via OpenOCD.
The port uses non-blocking polling UART communication with hardware flow control for Bluetooth controller. It was tested and achieved up to 1.8 Mbps bandwidth between two Max32630FTHR boards.
The [Maxim ARM Toolchain](https://www.maximintegrated.com/en/products/digital/microcontrollers/MAX32630.html/tb_tab2) is free software that provides peripheral libraries, linker files, initial code and some board files. It also provides Eclipse Neon and Maxim modified OpenOCD to program the microcontroller together with various examples for Maxim Cortex M4F ARM processors.
For debugging, OpenOCD can be used. The regular OpenOCD does not support Maxim ARM microcontrollers yet, but a modified OpenOCD for use with Maxim devices can be found in the Maxim ARM Toolchain.
In the Maxim Toolchain installation directory, there is a setenv.sh file that sets the MAXIM_PATH. MAXIM_PATH needs to point to the root directory where the tool chain installed. If you're lucky and have a compatible ARM GCC Toolchain in your PATH, it might work without calling setenv.sh script.
The examples can be compiled using GNU ARM Toolchain. A firmware binary can be flashed either by copying the .bin file to the DAPLINK mass storage drive, or by using OpenOCD on the command line, or from Eclipse CDT.
In each example folder, e.g. port/max323630-fthr/example/spp_and_le_streamer, you can run "make" again to build an .elf file in the build folder which is convenient for debugging using Eclipse or GDB.
Toolchain and Eclipse guide can be found in README.pdf file where the Maxim Toolchain is installed. Please note that this port was done using Makefiles.
There are two ways to program the board. The simplest way is drag and drop the generated .bin file to the DAPLINK mass storage drive. Once the file is copied to the mass storage device, the DAPLINK should program and then run the new firmware.
printf messages are redirected to UART2. UART2 is accessible via the DAPLINK Programming Adapter as a virtual COM port at 115200 baud with no flow control. If this doesn't work for you, you can connect P3_1 (UART TX) of the MAX32630FTHR board to a USB-to-UART adapter.
