System Workbench for STM32

hi, i met the same problem ,and after read this page, i had solved .

------------------------------
seems the simplest way to deal with this is to just use

reset_config none separate

Then the reset is done internally over the SWD channel with no pins used.

--------------------------
edit the *.cfg file in the project as below:

# use hardware reset, connect under reset
#reset_config srst_only srst_nogate
reset_config none separate
