STLink V2 Not recognizing STM32CubeProgrammer?

[sriniharish]

ST Link not recognizing STM Cube Programmer? - From screenshot you can see NO ST Link detected in serial number drop down and has no target information. I can (and did) upgrade firmware, On doing so, it's throwing following error( ST-Link device lost when exiting upgrade mode). Still won't connect. Keep getting "UR connection mode is defined with the HWrst reset mode" log entry.

>> I suspect there's something in the latest (last year or so) versions of STM32CubeIDE that causes fake programmers to fail. You could also use a version from before that, will probably work.

Hi AScha.3,

I'm using wio E5 Development board from seeed(https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/#lorawan-end-node). Also, the ST-Link device is not clone. It was working fine earlier, all of sudden it's throwing error.

so: same stlink working before ? and no update made ?

because this is exactly , what newer stm program doing, when detecting a clone. (or non stm cpu)

otherwise...try new USB cable and /or other port on PC.
