** [tickets:#359] Unable to connect to stm8s105 targets. (Other stm8 targets
work)**
**Status:** new
**Milestone:** 0.11.0
**Labels:** stm8s
**Created:** Tue Aug 16, 2022 04:35 PM UTC by brad roy

**Owner:** nobody
I'm unable to connect to stm8s105 chips. Other stm8 chips - the stm8s103f3
works, and the stm8l151c6 also connects. I *can* connect and read/write to
flash and opt on the same stm8s105k6 chips with the stm8flash tool, using the
same stlink.

**writing flash with stm8flash (same chip/programmer)**
$ stm8flash -c stlinkv2 -p stm8s105k6 -w ./Blink.ino.hex
Determine FLASH area
Due to its file extension (or lack thereof), "./Blink.ino.hex" is considered as
INTEL HEX format!
