Openocd has an initial 'configuration' mode where you setup adapter and
device, then an 'exec' mode to run the other commands.
You need to use `-c init` to switch from 'configuration' to 'exec'.
This below should work
~~~
openocd -f interface\stlink-dap.cfg -f target\stm8s103.cfg -c "init;load_image
{C:\Users\Max\Documents\PlatformIO\Projects\stm8_testing\.pio\build\stm8sblue\firmware.bin}
0x8000;reset;shutdown"
~~~
Agree, would be good to align the stm8 code with the rest of openocd.
`load_image` is normally used to load in RAM, that's why the `verify` flag is
not present.

Using PlatformIO I've generated a blinky firmware for an STM8S (firmware in
intelhex format attached).
I can also flash the target file using https://github.com/vdudouyt/stm8flash
~~~
stm8flash.exe -c stlinkv21 -u -p stm8s103?3 -c stlinkv2 -s flash -w
"C:\Users\Max\Documents\PlatformIO\Projects\stm8_testing\.pio\build\stm8sblue\firmware.ihx"
Determine FLASH area
libusb: error [init_device] device
'\\.\USB#VID_062A&PID_5918&MI_01#9&1953ACC1&0&0001' is no longer connected!
Due to its file extension (or lack thereof),
"C:\Users\Max\Documents\PlatformIO\Projects\stm8_testing\.pio\build\stm8sblue\firmware.ihx"
is considered as INTEL HEX format!
2576 bytes at 0x8000... OK
Bytes written: 2576

And it runs fine. Using OpenOCD, I can connect to the chip

Is my `"program
{C:\Users\Max\Documents\PlatformIO\Projects\stm8_testing\.pio\build\stm8sblue\firmware.bin}
0x8000 verify reset exit"` command malformed? I've tried a lot of different
combinations but I can't get past that errror. Or is `write_image` not
supported for STM8 targets?
