Topic: Portenta USB ports shorted together? (Read 134 times) previous topic - next topic


Looks like R44 and R45 short the two USB ports (USB-F and USB-H) together.  Anyone know why?  Something to do with booting?


Reference manual RM0399 says the bootloader checks the USB-FS, not the USB-HS, so R44 and R45 need to be in place in order to boot thru the installed USB connector.  So in order to free up the second USB port, I need to remove those resistors...
