Overview
7+
********
8+
9+
MSPM0G350x microcontrollers (MCUs) are part of the MSP highly integrated, ultra-low-power 32-bit MCU
10+
family based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating at up to 80-MHz frequency.
11+
These cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature
12+
ranges from -40°C to 125°C, and operate with supply voltages ranging from 1.62 V to 3.6 V.
13+
14+
The MSPM0G350x devices provide up to 128KB embedded flash program memory with built-in error correction
15+
code (ECC) and up to 32KB SRAM with a hardware parity option. These MCUs also incorporate a
16+
memory protection unit, 7-channel DMA, math accelerator, and a variety of peripherals including
17+
* Analog:
18+
* Two 12-bit 4-Msps ADCs
19+
* Configurable internal shared voltage reference
20+
* One 12-bit 1-Msps DAC
21+
* Three high speed comparators with built-in reference DACs
22+
* Two zero-drift zero-crossover op-amps with programmable gain
23+
* Digital:
24+
* Two 16-bit advanced control timers
25+
* Five general-purpose timers
26+
* One 16-bit general-purpose timer for QEI interface
27+
* One 32-bit high resolution general-purpose timer
28+
* Two 16-bit timers with deadband support and up to 12 PWM Channels
29+
* Two windowed-watchdog timers
30+
* One RTC with alarm and calendar modes.
31+
* Data Integrity and Encryption
32+
* One AES HW accelerator capable of CTR, CBC, and ECB modes
33+
* One Cyclic Redundancy Check (CRC) accelerator
34+
* One True Random Number Generator (TRNG)
35+
* Communication
36+
* Four UARTs, one with support for advanced modes such as LIN and Manchester
37+
* Two I2C supporting SMBUS/PMBUS and speeds up to FM+ (1Mbits/s)
38+
* Two SPI, one with max speed 32Mbits/s
39+
* One CAN interface supporting CAN 2.0 A or B and CAN-FD

49+
=========
50+
51+
- Onboard XDS110 debug probe
52+
- EnergyTrace technology available for ultra-low-power debugging
53+
- 2 buttons, 1 LED and 1 RGB LED for user interaction
54+
- Temperature sensor circuit
55+
- Light sensor circuit
56+
- External OPA2365 (default buffer mode) for ADC (up to 4 Msps) evaluation
57+
- Onboard 32.768-kHz and 40-MHz crystals
58+
- RC filter for ADC input (unpopulated by default)
59+
60+
Details on the MSPM0G3507 LaunchPad can be found on the `TI LP_MSPM0G3507 Product Page`_.
61+
62+
Supported Features
63+
==================
64+
65+
The MSPM0G3507 LaunchPad development board configuration supports the following hardware features:
66+
67+
+-----------+------------+-----------------------+
68+
| Interface | Controller | Driver/Component |
69+
+===========+============+=======================+
70+
| NVIC | on-chip | nested vectored |
71+
| | | interrupt controller |
72+
+-----------+------------+-----------------------+
73+
| SYSTICK | on-chip | system clock |
74+
+-----------+------------+-----------------------+
75+
| UART | on-chip | serial |
76+

80+
+-----------+------------+-----------------------+
81+
| CLOCKMUX | on-chip | clockctl |
82+
+-----------+------------+-----------------------+
83+
84+
More details about the supported peripherals are available in `MSPM0G3507 TRM`_.
85+
Other hardware features are not currently supported by the Zephyr kernel.
86+
87+
Building and Flashing
88+
*********************
89+
90+
Building
91+
========
92+
93+
Follow the :ref:`getting_started` instructions for Zephyr application development.
94+
95+
For example, to build the blinky application for the MSPM0G3507 LaunchPad:
96+
97+
.. zephyr-app-commands::
98+
:zephyr-app: samples/basic/blinky
99+
:board: lp_mspm0g3507
100+
:goals: build
101+
102+
The resulting ``zephyr.bin`` binary in the build directory can be flashed onto
103+
MSPM0G3507 LaunchPad using the steps mentioned below.
104+
105+
Flashing
106+
========
107+
108+
Open OCD is used to program the flash memory on the devices. It may be necessary in earlier versions to use a branch of open OCD onto the device.
109+
110+
Before OpenOCD is public, one can clone `This Repo <https://github.com/nmenon/openocd/tree/mspm0>`_, and then this can be built with
111+
112+
```
113+
cd <cloned_OPENOCD_dir>
114+
./bootstrap (when building from the git repository)
115+
./configure --enable-xds110
116+
make
117+
sudo make install
118+
```
119+
120+
Then after the build, it is possible to flash the device by passing additional arguments to the flash command
121+
122+
```
123+
west flash --openocd <path to cloned dir>/src/openocd --openocd-search <path to cloned dir>/tcl
124+
```
125+
126+
127+
`UniFlash`_ can also be used to program the flash memory if needed. The flash utility,
128+
however, requires the use of 8-byte aligned words, so adding alignment to the linker file is necessary.
129+
130+
Debugging
131+
=========
132+
133+
The flashing method described above does not include symbols. Thus, debugging requires an additional step to load the symbols.
134+
This section shows how to debug the MSPM0G3507 LaunchPad board using `CCS IDE`_. More information
135+
on debugging using CCS can be found in `CCS User's Guide`_.
136+
137+
In general, the steps for debugging in CCS are:
138+
139+
1. Open CCS
140+
2. Go to :menuselection:`Window --> Show View --> Target Configruation`
141+
3. Import target confguration by right clicking User Defined, selecting Import target configuration and pointing to the lp_mspm0g3507/support/MSPM0G3507.ccxml
142+
4. Launch target configuration by right clicking the new MSPM0G3507.ccxml file and clicking Launch target configuration
143+
5. Plug in the device and connect to it by going to :menuselection:`Run --> Connect Target`
144+
6. Go to :menuselection:`Run --> Load --> Load Symbols and load in the zephyr.elf file loaded`
145+
7. Use CCS to debug
146+
