Hello,

I have just bought a NUCLEO STM32H723-ZG board and wanted to use a J-Link connection for Tracealayzer (percepio.com/tracealyzer/trace…cealyzer-for-zephyr-rtos/).

I have then understood a need to uprade the firmware to add a J-Link interface. I have followed these steps: segger.com/products/debug-prob…j-links/st-link-on-board/.

Everything is ok until last step.

STLinkReflash tool ends up with Error "Cannot find an ST Link" (see error.png attached file).

However, the STLink is detected by Windows (see ST_Link.png attached file)

My system configuration is the following:

- Windows 10
- STLinkReflash_190812
- en.stsw-link009
- JLink_Windows_V788e_x86_64

Any help or clue would be greatly appreciated .

Best Regards,

Vincent
