[lca2018-chat] The Tomu in your Welcome Pack

[Josh Bassett]

I got the Tomu in my swag (thanks Sean and Tim).

I'm having trouble uploading a BIN file to the device. I managed to download and compile the blinky example, but when I try uploading it to the Tomu nothing happens.

I'm using minicom with xmodem (on macos).

Anyone else got it working?

Our crowdfunding campaign ends on 8 February, but we've got a pre-production unit just for you.  More information about Tomu, including hardware schematics and source code, is available at https://tomu.im/.  Here's some quick information.

If not, you can fold over a thick piece of paper and use that to make contact.  Business cards work well for this approach. Remember that Tomu was designed to be left in your USB port.

The new bootloader can load code using dfu-util, which is likely present in your package manager.  We've brought the factory test jig here to LCA, and you can use it to flash this new bootloader.  It's a quick three-second process, and gives you a peek into how the factory process works.
