JTAG can't connect to target board

[jxin.1]

I newly get a SPC56B-Discovery board. I have installed the SPC5Studio and UDE STK 5.0 on my PC. I select an example project and build OK with SPC5Studio. Then I connect the board to PC with USB cable. The PC can recongnize "PLS USB JTAG Adapter for SPC5XXX A / B" and I enabled the VCP function referred to this link:

Then I unplug and plug the USB cable, the VCP COM ports occur, the drivers seems OK now, and the preloaded blinky program works fine on the board. But when I load debug.wsx from the example project with UDE STK 5.0, it gives these errors as same as the link above:

Message from component 'PpcJtagTargIntf' :

Can't connect target !

Message from component 'PpcJtagTargIntf' :

No JTAG client found !

Please check:

- target power supply

- JTAG cable connection

- target configuration

All jumpers are in the default config. Do you have any sugession?

Thanks!

I have the same problem as mentioned by the user above. UDE STK 5.0 and Windows 10.

All the drivers are installed properly and the Load VCA settings are ticked.

I am getting the same error though.

Has this issue been solved?

Thank you!
