(Other stm8 targets work)** **Status:** new **Milestone:** 0.11.0 **Labels:** stm8s **Created:** Tue Aug 16, 2022 04:35 PM UTC by brad roy **Last Updated:** Tue Aug 16, 2022 04:35 PM UTC **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. **STM8s105.cfg** $ openocd -f interface/stlink-dap.cfg -f target/stm8s105.cfg Open On-Chip Debugger 0.11.0-g228ede4-dirty (2022-07-25-13:51) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html srst_only separate srst_gates_jtag srst_open_drain connect_deassert_srst Info : Listening on port 6666 for tcl connections Info : Listening on port 4444 for telnet connections Info : STLINK V2J17S4 (API v2) VID:PID 0483:3748 Info : Target voltage: 3.235884 Error: stlink_swim_enter_failed (unable to connect to the target) **STM8s.cfg (with the '105 chip)** $ openocd -f interface/stlink-dap.cfg -f target/stm8s.cfg Open On-Chip Debugger 0.11.0-g228ede4-dirty (2022-07-25-13:51) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html srst_only separate srst_gates_jtag srst_open_drain connect_deassert_srst Info : Listening on port 6666 for tcl connections Info : Listening on port 4444 for telnet connections Info : STLINK V2J17S4 (API v2) VID:PID 0483:3748 Info : Target voltage: 3.243799 Error: stlink_swim_enter_failed (unable to connect to the target) **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! 1986 bytes at 0x8000...
