OpenOCD as standalone stm8 flash programming

addthis.md

Add this to stm8s.cfg

proc program_device {filename flashstart} {
halt
wait_halt
load_image $filename $flashstart
sleep 10
reset halt
resume
sleep 10
shutdown
};

Usage

Invoke openocd with option ...

-c "program_device bin/main.ihx 0"

bin/main.ihx is your hex file

Example (xPack OpenOCD):

 openocd  -f scripts/interface/stlink.cfg -f scripts/target/stm8s.cfg -c "init"  -c "program_device bin/main.ihx 0"
