I have this ini settings:
[env:due]
platform = atmelsam
board = due
framework = arduino
debug_tool = stlink
upload_protocol = stlink
I get the following output:
Warn : target at91sam3X8E.cpu examination failed
embedded:startup.tcl:1070: Error: ** Unable to reset target **

NRST of ST-Link connected to the RESET pin?
Yes, the Stlink is connected to the 10pin JTAG port of the Arduino Due
And the connector is on the way right way around right?
Can you try adding
upload_flags =
-c
reset_config trst_only separate
to the platformio.ini and iterate the reset config through the available combinations (here, here) and see what works for uploading?
I have tried the flags as follows but it did not help !
upload_flags = -c reset_config none
upload_flags = -c reset_config trst_only
upload_flags = -c reset_config srst_only
upload_flags = -c reset_config trst_and_srst
Any other idea ?
picture of my setup:
Thanks for your help.
Just for testing, when you remove the upload_flags again, and hold down the Reset button of the board, then press the Upload button in VSCode and only release the code shortly after the OpenOCD output appears (or the OpenOCD output appears to briefly halt), does uploading work then?
No, it does not help
Since I don’t have a Arduino Due I can’t help further. Either someone else from the forum has an idea, or open an issue at Issues · platformio/platform-atmelsam · GitHub. Due to the war, an answer will take its time however.
Thanks for your help !
Hi,
i found this conversation of yours.
I tried it and i am able to upload the blinky example with stlink/v2 but it does not blink. if i upload using usb programming port it blinks.
#extra_script.py:
from os import path

"-c", 'set CHIPNAME at91sam3X8E',
'-c', 'source [find target/at91sam3ax_8x.cfg]']
)
env.Append(
UPLOADERFLAGS=["-c", "telnet_port disabled; program {$SOURCE} 0x80000 verify reset; shutdown"]
)
env.Replace(

I would be very greatful for your help.
Thanks and regards.
With this hardware, does it just work with upload_protocol = stlink and no further scripts / modifciations?
No, i get the following message:

o_O all of this is very weird. Please report this to Issues · platformio/platform-atmelsam · GitHub for te developers. Due to the war, things may take a while though.
the modified script uploads the firmware.bin file but fails with .elf file.
UPLOADERFLAGS=["-c", “telnet_port disabled; program {/Users/phillip/Documents/PlatformIO/Projects/220310-081051-due/.pio/build/due/firmware.elf} 0x80000 verify reset; shutdown”]
if i try without platformio:
C:\Users\Phillip>/Users/phillip/.platformio/packages/tool-openocd/bin/openocd -d2 -s /Users/phillip/.platformio/packages/tool-openocd/scripts -f interface/stlink.cfg -c “set CHIPNAME at91sam3X8E” -c “source [find target/at91sam3ax_8x.cfg]” -c “telnet_port disabled; program {/Users/phillip/Documents/PlatformIO/Projects/220310-081051-due/.pio/build/due/firmware.elf} verify reset; shutdown;”
