I am writing this to help.
I have just received my EVB STM32MP257F-DK.
When I have connected my USB cable in "USB PWR STLNK".
LD5 and LD6 were RED, LD11 was flashing GREEN once.
Installed the SD card and nothing, no boot ?
Win11 was claiming that the driver is fine and the latest.
The USB port were displayed as regular: USB PORT COM9 and COM10.
Pressing the RESET button B1 nothing: No BOOT, no bad character on both ports ???
Disconnecting the USB cable was well detected by Tera Term but nothing else.
I have decided to install STM32CubeProgrammer Winn64 to check ithe ST-LINK by trying to connect.
During the installation of the tool, the installer has advised that it is installing a driver.
With no intervention, my EVB started to work, booting LINUX and all the LEDS have started flashing like a chritmas
Resetting the EVB, we can see Linux booting on port COM10 115200,8,N1
See the image attached when the driver work fine and how it is displayed in Win11 device manager.
Have fun.
Best regards,
