Updating firmware via USB DFU

Post by brahn » Thu Apr 11, 2019 6:49 pm

Important: After flashing via any of the methods below the BCS must be power cycled before it will leave DFU mode. Pressing the reset button is not sufficient.

Windows:
For Windows there are some one-time steps needed to set up a USB Driver for the BCS:

1. Download Zadig
2. Connect the BCS to the PC via USB and use Zadig to select the BCS and install the libusbK drivers.

After the drivers are installed you can use the bcs-dfu utility that is in the attached file:

Run the utility, select the dfu file and press Flash to update the firmware. When flash is complete, unplug USB and power cycle the BCS.

Mac:
The instructions for Mac are the same as for linux, but to get the dfu-util package we recommend using Homebrew to install dfu-util.

Linux:
Install the dfu-util package from your distribution and run the command

Code: Select all

dfu-util -D bcs482.dfu

I've updated the ZIP to include the QT platforms folder. That should fix it.

Running the installation command line under Homebrew (/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homeb ... er/install)") it asks for a password - it shows a key. What do I do to get around this?

That's going to be your administrative sudo password to allow installation of homebrew.

Now my 482 is bricked.... Firmware showed complete with no errors with DFU update app. I can no longer see the 482 with BCS finder and its not pulling an IP address on my network

Have you done a hard reset after the update? Have you tried updating again?

Are you power cycling it after the flash? That needs to be done to take it out of DFU mode. Also unplug the USB before power cycling.
