Jarrah White, debugging the field reversal issue has been delayed due to COVID-19 related disruption, sorry. I hope to be able to address the issue in a firmware update and I do have some ideas I’d like to try. If you happen to have an AVR ICSP programmer, you can even try an alternate firmware image. Please see here for general instructions and information regarding updating the firmware on the Koryuu.
Please give me a holler if you’re interested.
