NUCLEO-H7S3L8 is not detected

OS: Kubuntu Linux 24.04

IDE: STM32CubeIDE 1.17.0

Hello,

STM32CubeIDE shows the message "No ST-LINK detected!". Neither the command "lsusb" nor VirtualBox are showing the device. I tried different cables and different USB ports. The quick start guide (UM3276) tells me to "install the STLINK-V3EC USB driver available on the www.st.com website", but there is only a Windows driver.

In contrast to this, a NUCLEO-F446ZE board gets detected fine.

Is it a dead board or is there any driver I have to install before? If so, where can I find it?

Since the NUCLEO-F446ZE uses ST-Link v2.1 (micro USB) and NUCLEO-H7S3L8 uses ST-Link v3 (USB-C), I tried to connect my external ST-Link v3 SET (micro USB) and it gets also detected.

The cable and USB port are working with other USB-C devices.

When using the ST-Link v3 SET, I get the error "Could not determine GDB version using command: arm-none-eabi-gdb --version". So I downloaded "en.st-link-server_v2.1.1-2" and wanted to install the GDB server, but here I get the message:

"lready installed version is newer or equal: v2.1.1 (2023-06-02-08:34)
NOT downgrading. Aborting stlink-server installation."

In the past, it was much easier to start with programming.

Hello @oxc07w2 

Make sure that the ST-LINK firmware is up to date. To upgrade the ST-LINK firmware to the latest version, you can use the STM32CubeProgrammer tool.

If the board is not being detected, try selecting the "Connect under reset" mode and holding the reset button while attempting a "Full Chip Erase" to clear the flash memory.

Check the jumpers on the board and make sure that they are set correctly. You can follow the recommendations described in the UM3276, which contains all the jumpers and solder bridges with their functions.
