Terminated OpenOCD Process with EV-COG-AD4050LZ

Takahiro
on Feb 15, 2019

Hi,all.

I am using EV-COG-405Z in the following environment, currently.

IDE：CrossCore Embedded Studio
IDE version：2.8.44.201803091352
DFP:AnalogDevices.ADuCM4x50_DFP.3.2.0
BSP:AnalogDevices.EV-COG-AD4050LZ_BSP.3.1.0
CMSIS:ARM.CMSIS.5.1.1

I copied and executed Blinky_example (EV - COG - AD 4050 LZ) from CMSIS Pack Manager.
After that, the following message is displayed on the console and the program is not executed.

Open On-Chip Debugger (Analog Devices CCES 2.8.0 OpenOCD 0.9.0-g5030ad7) 0.9.0

What are the possible causes of this problem?

Thanks

    Hi Takahiro,

    This problem usually happens when there is a communication problem between the target and the programmer. Maybe the MCU

    is still hanging for some reason and trying to download the code will terminate the process.

    Try to do this before downloading the code

    1. Press and hold  BOOT and Reset button at the same time.

    2. Release Reset button while holding the BOOT button.

    3. Finally release BOOT button.

    Now try to download the code again it should work now.
