Hello,
I got problems to get OpenOCD 0.12.0 running with a Raspberry Pi 4 and a
STM32F401 microcontroller.
I tested the SWD configuration with a Raspberry Pi 2 where I was succesfull.
Now after also reading some threads, I adapted my configuration to the RPi4 but
it still stops at this point:
~~~
Open On-Chip Debugger 0.12.0-rc1+dev-00023-gae937791d (2022-10-04-23:20)
Licensed under GNU GPL v2
For bug reports, read
http://openocd.org/doc/doxygen/bugs.html
Info : BCM2835 GPIO JTAG/SWD bitbang driver
Info : clock speed 2001 kHz
Info : SWD DPIDR 0x00000000
Info : Listening on port 6666 for tcl connections
Info : Listening on port 4444 for telnet connections
~~~
My Pin configuration is:
Function | GPIO|
---------- | ---------- |
nRST | 13 |
SWDCLK | 24 |
SWDIO | 25 |
My raspberrypi2-native.cfg looks like this:
~~~
# SPDX-License-Identifier: GPL-2.0-or-later
#
# Config for using Raspberry Pi'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 and the cable is short enough.
#
# Do not forget the GND connection, pin 6 of the expansion header.
#
adapter driver bcm2835gpio
bcm2835gpio peripheral_base 0xFE000000
# Transition delay calculation: SPEED_COEFF/khz - SPEED_OFFSET
# These depend on system clock, calibrated for stock 700MHz
# bcm2835gpio speed SPEED_COEFF SPEED_OFFSET
bcm2835gpio speed_coeffs 236181 60
# Each of the JTAG lines need a gpio number set: tck tms tdi tdo
# Header pin numbers: 23 22 19 21
adapter gpio tck -chip 0 11
adapter gpio tms -chip 0 25
adapter gpio tdi -chip 0 10
adapter gpio tdo -chip 0 9
# Each of the SWD lines need a gpio number set: swclk swdio
# Header pin numbers: 23 22
adapter gpio swclk -chip 0 24
adapter gpio swdio -chip 0 25
# If you define trst or srst, use appropriate reset_config
# Header pin numbers: TRST - 26, SRST - 18
# adapter gpio trst -chip 0 7
# reset_config trst_only
adapter gpio srst -chip 0 13
reset_config srst_only srst_push_pull
# or if you have both connected,
# reset_config trst_and_srst srst_push_pull
~~~
And my openocd.cfg like that:
~~~
source [find interface/raspberrypi2-native.cfg]
transport select swd
set CHIPNAME stm32f401
source [find target/stm32f4x.cfg]
reset_config srst_nogate
adapter srst delay 100
adapter srst pulse_width 100
init
targets
reset halt
flash erase_sector 0 0 7
flash write_bank 0 test_fw.bin 0
reset
shutdown
~~~
Did anyone manage to get OpenOCD 0.12.0 running on a RPi4?
Thanks in advance!
