# Connecting to the JTAG port can be done using the 4 headers on the i9+:
# J2: TDO
# J3: TDI
# J4: TMS
# J5: TCK
# wuxx's extension board's JTAG isn't compatible with the i9+ headers.
# The extension board's pogopins must be isolated to avoid shorts.
# However, is provides PMOD-compatible headers and the ethernet IOs are compatible.
# See https://github.com/wuxx/Colorlight-FPGA-Projects#ext-board for more infos.
