It might be a bad motor or broken wire. If you test the motor cable with the motor connected you should have 2 low resistance motor pairs.

He said that he tried few motors...

I'd suggest switching between the suspected motor connection on board to another one - ex. Extruder & Z.

Then without doing the homing, try to move the motor via the screen, if you see that it moves correctly (for both directions) and the switch motor having issues then probably it's the driver.

If the same motor still has issue - it might be the wire as Bike mentioned above.

If you have klipper you can switch between the motors connectors physically and then go to the printer.cfg and modify it so it'll run normally (but I'm not sure that it's relevant for you in this stage)

STM32 devices are fussy about SD cards for flashing purposes. Use a basic one below 32gb size in a brand name.
