    Since I currently don’t have any USB programmer to flash the initial firmware, I would like to do that with a Raspberry Pi which, without any conversion, only handles 3.3V. I could not find out the voltage on the OSSC’s JTAG from the schematics though.

    Ok, now that I have finished soldering the OSSC, I could measure the voltage and it’s 2.5V, so I will try to use a bidirectional voltage converter.
