# TMS750LC43xx

# Prerequisites

Download and install:
1) "Code Composer Studio" - https://www.ti.com/tool/CCSTUDIO
2) "F021 Flash API - Software" - https://www.ti.com/tool/F021FLASHAPI

Note: Avoid using spaces in the paths. Consider renaming "F021 Flash API" to "F021_Flash_API".

# Build

## Build from command line (msys, cygwin, etc)

1) Setup default configuration:

```
cp config/examples/ti-tms570lc435.config .config
```

2) Build passing in CCS_ROOT and F021_DIR make variables:

Windows:
```
make CCS_ROOT=/c/ti/ccs1250/ccs/tools/compiler/ti-cgt-arm_20.2.7.LTS F021_DIR=/c/ti/Hercules/F021\ Flash\ API/02.01.01
```

Mac OS:
```
make CCS_ROOT=/c/ti/ccs1031/ccs/tools/compiler/ti-cgt-arm_20.2.4.LTS F021_DIR=/c/ti/Hercules/F021\ Flash\ API/02.01.01
make CCS_ROOT=/Applications/ti/ccs1250/ccs/tools/compiler/ti-cgt-arm_20.2.7.LTS F021_DIR=/Applications/ti/Hercules/F021_Flash_API/02.01.01
```
