Good morning everyone, i have a stm32_NUCLEO-L4R5ZI, https://goo.gl/abGdjK.

When i plug in it on my Mac OSX 10.14.2, i see the board but the online Mbed ide does not recognize it:

"Error: Target "NUCLEO_L4R5ZI" is not recognized" "Info: Unable to download. Fix the reported errors..."

I updated the STLink to the last version V2J32M22.

Someone can help me? i tried all guides i found in the Mbed website.

Hi Davide,

Which version of mbed-cli are you using?

Can you use "mbed detect" to see if mbed-cli detecting the target?

Does drag-n-drop download method work for you? In finder, drag the bin image to the STLink drive.

Hi Desmond, i'm using the web compiler: https://ide.mbed.com/compiler/

Do you think that i need to donwload the cli from GitHub? Can i use it with the PlatformIO?

I would say using mbed-cli gives you more benefit for developing, but online compiler is very convenient, so it's up to you.

Platform IO supoprts mbed framwork, you can find more information here https://platformio.org/frameworks/mbed.

Back you your original question... Can you provide more information, like the screenshot of the error, what example are you using. Doesn't the drag-n-drop method work?

The message "Error: Target "NUCLEO_L4R5ZI" is not recognized" "Info: Unable to download. Fix the reported errors..." seems to be a compilation error from the online compiler and not a MacOS or USB driver issue.

The board seems to be supported by mbed : https://os.mbed.com/platforms/NUCLEO-L4R5ZI/

Have you added the board to your boards ? (Click the button "Add to your Mbed compiler") ?

After doing this, it creates the mbed "hello world" example : "Nucleo_blink_led". I can compile this (Compile -> Build) for this target without errors.

With the Web Mbed 1.10.25.0 it works.
