## Flashing the device
|
|
|
|
The STM32L496G-DISCO board includes an on-board ST-LINK programmer and can be
|
|
flashed using OpenOCD. The board can be flashed with:
|
|
|
|
```
|
|
make BOARD=stm32l496g-disco flash
|
|
```
|
|
|
|
and debug via GDB with
|
|
```
|
|
make BOARD=stm32l496g-disco debug
|
|
```
|
|
|
|
## Supported Toolchains
|
|
|
|
For using the STM32L496G-DISCO board we recommend the usage of the
|
|
[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
|
|
toolchain.
