Problem to execute a TEST application on the SPC56EL70L5

Postby MechatronicIng » Wed Feb 19, 2014 4:36 pm

Hi to evreyone,
I'm a new user of the forum, I hope that someone could help me.
My problem is the following:
I'm starting to use a SPC56L-Discovery board that I connect with the PC through the SPC5-UDESTK jtag-usb adapter. I installed the SPC5Studio and the UDE 4.0 to debug my board and load programs on it.
But I have a "strange" error following the steps of the document AN4321 “Getting started with the SPC56LDiscovery”. In fact, all goes perfectly when I generate and compile the application, but when I try to debug it (and automatically it opens the UDE) I have this error:

-Message from component 'PpcJtagTargIntf' :
Can't connect target !

Message from component 'PpcJtagTargIntf' :
No Lockstep mode on target detected when using LSM configuration !

Message from component 'PpcJtagTargIntf' :
No JTAG client found !
Please check:
- target power supply
- JTAG cable connection
- target configuration

Message from component 'UDEDebugServer' :
Unable to establish connection . To correct the situation, check configuration file entries and try again.

Someone could help me? I don't know what I can do.
Thanks to all

Are you using SPC5Studio 2.0? I just tried the two demos for the DiscoveryPlus board (with and without ChibiOS) and both work. I don't see that message related to lockstep mode.

I can suggest:
1) Check versions of SPC5Studio and UDE Desktop (make sure to use the latest UDE from PLS web site).
2) Try erasing the chip using the tools in UDE.
3) Make sure to use the files debug.wsx provided with the demos, those may contain specific workarounds.

If the above fails can you try another board? it is possible you got a defective one.
