I have STM32H745I- DISCO evaluation board. First, i used Touchgfx (V.4.14.0) and STM32H750B-DK for application template. After a couple of change and run, suddenly "run target" started to give an error and white screen came up on the LCD. It's saying that no Stm32 target found. I tried to connect to the device with using ST-Link Utility(V.4.5.0) tool but it gives "can't connect to the target..." error. I tried target->settings mode ->connect under reset and full chip erase. But it gives the same error and i couldn't make chip erase. Can someone please explain to me what sould I do to connect the device again?(By the way when i use firmware update i can conect the device but no other thing are working)
