### Introduction
|
|
|
|
The
|
|
[STM32L0538-DISCO](https://www.st.com/en/evaluation-tools/32l0538discovery.html)
|
|
discovery kit features an ultra low-power stm32l053c8t6 microcontroller with
|
|
64KB of FLASH and 8KB of RAM.
|
|
The board also provides an on-board 2.04\" E-paper display (not supported yet).

## Flashing the device
|
|
|
|
### Flashing the board using OpenOCD
|
|
|
|
The board can be flashed using OpenOCD via the on-board ST-Link adapter.
|
|
Then use the following command:
|
|
|
|
make BOARD=stm32l0538-disco -C examples/hello-world flash
|
|
|
|
## Flashing the Board Using ST-LINK Removable Media
|
|
|
|
On-board ST-LINK programmer provides via composite USB device removable media.
|
|
Copying the HEX file causes reprogramming of the board. This task
|
|
could be performed manually; however, the cpy2remed (copy to removable
|
|
media) PROGRAMMER script does this automatically. To program board in
|
|
this manner, use the command:
|
|
```
|
|
make BOARD=stm32l0538-disco PROGRAMMER=cpy2remed flash
|
|
```
|
|
@note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates
|
|
could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html).
|
|
|
|
### STDIO
|
|
|
|
STDIO is connected to pins PA9 (TX) and PA10 (RX) so an USB to UART adapter is
|
|
required. Use the `term` target to open a terminal:
|
|
|
|
make BOARD=stm32l0538-disco -C examples/hello-world term
|
|
|
|
If an external ST-Link adapter is used, RX and TX pins can be directly connected
|
|
to it. In this case, STDIO is available on /dev/ttyACMx (Linux case).
