Hello,

I'm new in the forum and in the use of STM32F10X.Recently to test a microcontroller STM32VLDISCOVERY the Atollic (V. 6.0.0) submitted the following error message:*******Error in initializing ST-Link device.Reason: (-8) Target held under reset.*******When testing the same code in other hardware error does not occur.Does anyone have idea how to fix? #stm32vldiscovery #stm32f100rb

Hello,

Maybe this failure is due to the devices are not actually starting, or not properly configured? Make sure that you are using the current firmware.Try connect under reset and check that the reset pin is connected properly.You can refer to the user manual:

Have you tried the STLink Utility ? Does it show the same issue?

Perhaps you can describe your connectivity on this board with more details to understood your case ?Regards
