I'm getting this error when trying to connect to a TWR-VF65GS10 tower board using DS-5 for vybrid and ULINKproD debugger:
RDDI-DAP-DS : Failed to initialise the target connection control object
ULP : Failed to open device.Error Code : -3
Failed to launch debug server. Command:
./vstrm_serverd_rddi -rddi_dap_dll librddi-dap_ulp.so.2 -rddi_dap_cfg /tmp/ds5_2089602664742980112.txt -pollrate 200
exited with error code: 1
I can connect using CMSIS-DAP on the TWR-VF65GS10 but not the ULINKproD. anyone else had this problem?
Hi,
The error code “-3” means that a connection to the ULink Pro D has failed.
Changing the USB port should fix the problem.
In addition, if you are using a Virtual Machine (e.g. Virtual Box), then you may need to configure the USB port as explained here.
Best regards,Marcelo
