USBwiz Boot Loader

version number of the boot loader may not match the version number of USBwiz.

Important Note: USBwiz chips come with no firmware on them.

8.3. Firmware Update

The easiest way to update USBwiz is by placing the new firmware on a SD card or a USB

mass storage device. Then, connect the media to USBwiz and send the boot loader (BL)

command to load the new firmware. Note that these commands are sent to a functional

firmware and they are firmware commands. If the firmware didn't execute, there could be a

need to set the mode pins in “force boot loader mode”. In this mode, the boot loader runs

in UART mode at 9600 and will accept the boot loader commands.

The firmware update file must be placed in the root directory. We recommend formatting

the media first.
