openOCD not halting my chip (srst not working?)
I am trying to flash code in my stm32 via SWD interface with a raspberryPi.(swd is bitbanged no stlink used)
With my raspberryPi Zero i followed this tutorial, wired the raspy with my stm32f105 together.
My openocd.cfg file looks like:
source [find interface/sysfsgpio-raspberrypi.cfg]
transport select swd
set WORKAREASIZE 0x2000
source [find target/stm32f0x.cfg]
reset_config srst_only srst_nogate
adapter srst delay 100
adapter srst pulse_width 100
bindto 0.0.0.0
init
targets
#reset haltmy sysfsgpio-raspberrypi.cfg file looks like:
#
# Config for using RaspberryPi's expansion header
#
# This is best used with a fast enough buffer but also
# is suitable for direct connection if the target voltage
# matches RPi's 3.3V
#
# Do not forget the GND connection, pin 6 of the expansion header.
#
interface sysfsgpio
# Each of the JTAG lines need a gpio number set: tck tms tdi tdo
# Header pin numbers: 23 22 19 21
sysfsgpio_jtag_nums 11 25 10 9
# Each of the SWD lines need a gpio number set: swclk swdio
# Header pin numbers: 23 22
sysfsgpio_swd_nums 11 25
# If you define trst or srst, use appropriate reset_config
# Header pin numbers: TRST - 26, SRST - 18
# sysfsgpio_trst_num 7
# reset_config trst_only
# sysfsgpio_srst_num 24
sysfsgpio_srst_num 7
reset_config srst_only srst_push_pull
# or if you have both connected,
# reset_config trst_and_srst srst_push_pull
