Hello,

Does the host PC detect the board?

Please ensure that the USB OTG/TYPE C port, usually specified as download, is correctly connected or have no damage.

Also, if you're using Windows please try with the steps on this thread:

HI Alde

It seems we should update the usb driver with the link, could you supply the correct driver for me ?

Hi,

From this link you may find the SDK for each platform:

https://developer.android.com/studio/releases/platform-tools

On a computer running the Windows® OS, install Google extra win USB driver, contained in the SDK package, if using Linux OS, add the following rules for udev rule file: /etc/udev/rules.d/51-android.rules

SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0777"

SUBSYSTEM=="usb|usb_device", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev"

Regards,

Aldo.

Hello,

The drivers needed are the .dll files you have on the package,

you'll need to install those.

Aldo.
