Build and load over serial
# First install FPGA toolchain and LiteX
# Build and load stuff
make bitstream
make load_bitstream
make load_app
# Manually write "reboot" in the terminal, in order to trigger the upload of the app
# Upload a ROM
python -m gateware.ecpkart64.uploader2 --port /dev/ttyUSB1 --csr-csv csr.csv --cic --file myrom.z64
# Turn on power on the N64SD-Card
Currently this doesn't work properly for some reason (sd-card driver does not manage to interact with the card properly). But these are the steps normally taken:
# Build
make bitstream
make app
# Format and mount an SD-Card with FAT
sudo mkfs.vfat -F32 /dev/...
sudo mount /dev/... /mnt/usb
# Mount it and copy files to it
cp build/kilsyth/software/app/app.bin /mnt/usb/
cp rom.z64 /mnt/usb/
# Create boot.json with your configuration
echo '{
"rom.z64": 0x40000000,
"app.bin": 0x20000000
}' > /mnt/usb/boot.json
# Unmount, insert and boot. Turn on N64.

Questions
How big is the ECPKart64 PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.2 mm thick.
What parts does the ECPKart64 use?
106 parts, built around the LFE5U-12F-6BG256C, SY8120B1ABC, IS42S16320F-7TL and XC6206P252MR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ECPKart64 KiCad files?
From the kbeckmann/ECPKart64 repository on GitHub, at the commit this page was made from: the board is hw/RevA/RevA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECPKart64 design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
