Known board issues

• Boards with an RGB/i80 LCD Driver show glitches when reading/writing files or turning on WiFi:
  WaveShare S3, Crowpanel 5" (both),
• Crowpanel: UARTs now working? (maybe tx and rx swapped)
• M5Stack Core2: Grove port not configured yet

Known app issues

• Chat app might crash when WiFi is on while starting the app. Chat might not reliably receive messages.
