[OpenOCD-user] OpenOCD on Raspberry Pi Zero to flash STM32F410 via SWD

[Maximin C. <max...@gm...>]

Hi,

I followed the Adafruit guide[1] () to flash an STM32F410 (on a Nucleo
Board,
but I don't want to use the STLink part) from a Raspberry Pi Zero and
connected directly the SWDIO, SWDCLK, GND and RST pins on my
STM32F410 (using the F410 datasheet, SWDIO is PA13 and SWCLK is
PA14)

Using my config file:

======
source [find interface/raspberrypi-native.cfg]
transport select swd

set CHIPNAME stm32f4x
source [find target/stm32f4x.cfg]

#reset_config srst_only
reset_config  srst_nogate

adapter_nsrst_delay 100
adapter_nsrst_assert_width 100

init
targets
reset halt

bcm2835gpio_swd_nums 25 24
bcm2835gpio_trst_num 7
bcm2835gpio_srst_num 18
======

and then call:
sudo openocd -f myconfigfile.cfg

OR calling directly the following command:
sudo openocd -f interface/raspberrypi-native.cfg -c "transport select swd"
-f target/stm32f4x.cfg

leads me to the exact same output:

instead of the target listing I'm expecting. (I don't even have the feared
'unknown' state listing. Is this even an error ? (I don't see the word
'error'
anywhere... !) Do I missing something ? (Probably !)

Any help would be gladly appreciated !
