hi Zoltan,

Just a quick note it seems the version/sha of Mbed OS you're using doesn't work out of the box with Mbed Studio (1.0) - it can't detect the Bluepill custom target.

After importing the application and upgrading to Mbed OS 6.0.0 (165be79392ae7b1bee4388d2bc8ed8281978f07c), then I can select the Bluepill and compile just fine. You may want to update the mbed-os.lib file.

Thanks, Marcelo

Hello Marcelo,

Thank you for the feedback. I have rebuilt the program with the mbed-os.lib rev. 165be79392.

Best regards, Zoltan

This does not appear to work anymore with the latest Mbed Studio (1.4.5).

After importing into Mbed Studio and clicking build, I get the following errors:

Traceback (most recent call last):
File "c:\mbed-os-bluepill\mbed-os\tools\targets\", line 151, in target
resolution_order = get_resolution_order(json_data, name, [])

order = get_resolution_order(json_data, par, order, level + 1)

parents = json_data[target_name].get("inherits", [])
KeyError: 'MCU_STM32F103x8'
The above exception was the direct cause of the following exception:
