I connected my STM32L476RG to the arduinoIDE with according settings.

And upload a Blink example from the IDE.

But I get these errors.

I am running mac with sierra.

I have eclipse with Ac6 for STM32 and it works with no problem.
How can I get STM32duino to work?
Thanks.

Hi @kuobakuoba,
Please, Could you try to update the STLink firmware.

ST-LINK, ST-LINK/V2, ST-LINK/V2-1 firmware upgrade

Hi!! @fpistm
I've tried but with no luck.

It was exactly the same error code as above.
Thanks.

Ok thanks for the test.
Probably that the stlink binary released do not support this boards or have an issue.
Could you test with the latest version 1.3.0:
https://github.com/texane/stlink/releases/tag/1.3.0

To test, use this command line, where binary file is the path to your bin built with arduino (See the build log to find the fullpath):
stlink/st-flash write 0x8000000

If it's work you could replace the binary installed by STM32Tools.
You also have the path in the build log (stlink_upload):
/User/...../packages/STM32/tools/STM32Tools/2017.5.12/tools/macosx/stlink/

Unfortunately I do not have Mac to perform the test.
Maybe @rogerclarkmelbourne has some clues about that?

@fpistm Sorry for the late reply.
To be honest,I don't know how to use these binaries.
But with some lucks or something I managed to get it work with the file you gave me.
I just clicked st-flash and copy all file in the bin folder to here(/User/...../packages/STM32/tools/STM32Tools/2017.5.12/tools/macosx/stlink/) and for some reason it just worked.
Thank you so much for your help.

Ok, so if its work with the updated file, I will do an update in the Arduino_Tools
