stm8flash

This is free and opensource software distributed under the terms of the GNU General Public License, either version 2 of the License, or (at your option) any later version.

For years, it was the only program that's able to communicate through the SWIM interface of ST-LINKs under Linux.

Since 2018, OpenOCD also offers the basic functionality, and also has support for on-target debugging. As of early 2018, stm8flash has wider device support, and better support for memory read/write operations.

Synopsis

stm8flash -c <stlink|stlinkv2|espstlink> -p <partname> [-s flash|eeprom|0x8000] [-r|-w|-v] <filename>

The supported file types are Intel Hex, Motorola S-Record and Raw Binary. The type is detected by the file extension.

Flash examples:

./stm8flash -c stlink -p stm8s003f3 -w blinky.bin
./stm8flash -c stlink -p stm8s003f3 -w blinky.ihx
./stm8flash -c stlinkv2 -p stm8s003f3 -w blinky.ihx
./stm8flash -c stlink -p stm8s105c6 -w blinky.bin
./stm8flash -c stlinkv2 -p stm8l150 -w blinky.bin

EEPROM examples:

./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -r ee.bin
./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -w ee.bin
./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -v ee.bin
