This document describes how to build the FPGA bitstream, including the
|
||
|
|
firmware, and get this programmed onto the flash of the Tillitis Key1
|
||
|
|
USB device.
|
||
|
|
|
||
|
|
The Tillitis Key1 kit includes:
|
||
|
|
|
||
|
|
- Tillitis Key1 USB device, marked MTA1-USB V1
|
||
|
|
- Programmer board based on Raspberry Pi Pico, with a white device
|
||
|
|
holder/jig
|
||
|
|
- USB-cable with micro-B plug, for connecting the programmer to
|
||
|
|
computer
|
||
|
|
- USB-C cable
|
||
|
|
- USB-C to USB-A adapter
|
||
|
|
|
||
|
|
Connect the programmer to the computer using the mentioned cable. It
|
||
|
|
is convenient to connect the USB device to the USB-C cable, and then
|
||
|
|
connect the cable to the computer. The latter using the USB-C-to-A, if
|
||
|
|
needed.
|
||
|
|
|
||
|
|
`lsusb` should list two new devies: `cafe:4004 Blinkinlabs ICE40 programmer`
|
||
|
|
and `1207:8887 Tillitis MTA1-USB-V1`.
|
||
|
|
|
||
|
|
The USB device is then placed correctly in the programming jig, and
|
||
|
|
the hatch closed. The USB device can remain in the jig during repeated
|
||
|
|
programming and testing cycles. The jig has a cutout to allow for
|
||
|
|
touching next to the LED where the touch sensor is located.
|
||
|
|
|
||
|
|
To install the software needed for building and programming, please
|
||
|
|
refer to [toolchain_setup.md](toolchain_setup.md).
|
||
|
|
|
||
|
|
You are now ready to generate the FPGA bitstream including the standard
|
||
|
|
firmware, and program the flash on the connected USB device. This should be run
|
||
|
|
as your regular non-root user, but the the programming is done (in the
|
||
|
|
Makefile) with `sudo tillitis-iceprog` (so sudo is expected be set up).
|
||
|
|
|
||
|
|
```
|
||
|
|
$ git clone https://github.com/tillitis/tillitis-key1
|
||
|
|
$ cd tillitis-key1/hw/application_fpga
|
||
|
|
$ make prog_flash
|
||
|
|
```
|
||
|
|
|
||
|
|
Your Key1 device should eventually be running the firmware with the LED
|
||
|
|
flashing white, indicating that it is ready to receive an app.
