CPT - Cannot Read MCU

18.01.2026, 14:58

Hello

I have a CPT with ISP Adapter

Every time I am trying to read an MCU I see

Adapter ISP_v1.0 S/N: B7BB66CA7C4990E4
JTAG Target not Found!!!

Last four ECU's all were infineon and none read.

Before this all was OK and I used the programmer a few times per week with no issues.

The LED on the ISP Adapter comes on as usual for a few seconds when I try to Read.

(EEPROM Programmer works OK)

Is there a test I can make to see if it is the CPT Programmer or ISP Adapter that may be causing the problem?

Thanks
