Hello Stefan,

Is it possible to set options and operation with using program in one command line?

yes, this should be supported

After this i´m not able to connect to the controller at all with the USB2000 CONTROLLER.

Do you mean that you are unable to have UniFlash/CCS communicate to the USB2000 JTAG probe? Or that you are unable to have UniFlash/CCS communicate to the F28379 via the USB2000 JTAG probe?

Thanks

Hello Ki,

I´m unable to have UniFlash/CCS communicate to the F28379 via the USB2000 JTAG probe, at all.

Stefan

What kind of error do you get when you try to connect to the device using CCS?

Hello Ki,

the programm on the F28379S is running and i can communicate via CAN to the controller, the application is working. But i can´t connect via USB2000 JTAG any more.

What are the results of a JTAG connectivity test?

Hi Ki,

here are the results from JTAG connectivity test:

Your low-level JTAG connection is good. That is a good sign.

Likely the device itself is in a bad state.

The below article details many of the errors you see:

Error -2134 seems to be the main culprit here:

It could be that you flashed a location that shouldn't have been flashed. This can accidentally lock the device. Please check your device documentation, see if there is a way to recover from such a situation
