[SOLVED] J-Trace Pro V2.00 for ARM Cortex-M stopped working when using J-Trace Isolator with latest firmware upgrade

Dear friends at Segger, the latest firmware prevents our J-Trace Pro probe to work with the J-Trace Isolator V1.0B.

The "Target power " LED keeps on blinking red and the debugger cannot connect.
If we remove the isolator board, then the LED blinks alternatively orange and green, and it is possible to connect to the target and debug again.

Thank you for your attention.
Kind Regards
