@mythbu thanks a lot for sharing this! I remember my own long nights back in 2018, where @sza2-sza2 and me finally got i2s working (that forum thread you found and linked above ). Sorry that I did not see your original question earlier, only the solution now - if I did, I might have been able to help a bit. Anyway, glad to hear you got it working! But what I don‘t understand: why did the i2s support disappear again after b177? As I‘m using only custom openwrt images, I lost track of details happening in the official onion releases. Since b177, i2s support was a ticked checkbox in my mind…

@JeffZhou Thanks a lot, for your response! I think that the 2nd point (VCC current) was the root cause of my issues: I used an AWG30 wire for all VCC lines which was too thin to carry the current. Regarding the UART <-> USB-Bridge the issue still persists, it requires a little fiddling: opening the serial connection after counting to three after plugging in. Then it worked booted in 100% correctly so far. Best Regards!
