Hard resetting via RTS pin...
I do need to press reset to run the code once it downloads. FYI

the serial output , the code is the touch program that comes installed on it with some SPI pin id stuff and display the cores and chip id. just test code that works always. test the display as well. I’m using it on a XEB.
