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/basic/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.
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/basic/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).
