The demo software worked except for the image and video display. No suitable files. This demo was deleted and replaced by Tilen Majerle gitub usb dual host bin application using stm32cube programmer. Issue one, only some usb memory sticks work. All are 16GB or less, and fat or fat32. One memory stick writes a file and performs perfect. The others bring up an error when the mcu attemps to write text to a file on the stick. They mount and unmount according to the lcd touch display. Just will not write. Any ideas as to why some usb sticks work and others will not? The stick that works is the older. Issue 2, This app was deleted and the demo from STMs web page installed. It is their compiled hex file and cubeprogrammer was used to download to mcu. After a successful calibration of the lcd touch screen the 6 icons are displayed. However the touch function no longer works correctly. Touching one icon brings up another icons function. However no further touch features will work. You have reset the mcu to get the front page up again. It did work correctly out of the box but not now with their web page app presumed the same one! Any suggestions?
