Hello everybody,
I am testing a newly assembled Booz main board. Loading the USB Boot Loader went smoothly.
However, when I try to program it through USB, I get a no USB device error. USB access rights and device rules are OK. Dmesg and lsusb do not detect the board.
I have tested all the mini-USB connections on the board and everything is fine. The board input voltage through USB is 5V (USB_VBUS), however USB_VBUS_3V3 line (P0.23 pin) has 0V - the voltage drop on R9 is 5V!
Any suggestions what to try next?
Thank you for your help.
Kind regards,
Marko
