Hello everyone, I just wanted to chime in and mention that with UIFlow firmware 1.7.1.1 that I also do not have the RGB leds showing up as hardware options in block view in the UIFlow IDE. I do not have the "Set bus power mode" as an available block. I CAN however call rgb.setColorAll() and other rgb functions from the python code and get the correct output from the LED strips on the Core2 M5go Bottom2 hardware. So I am not sure what that means as far as where the bug is. Thank you!

@mati I bought 5 16gb cards, tested them yesterday, they work fine. But, I have 32gb that work in all my pc's and my phone but don't work in my m5paper. I did have to use as CS of 4 in the SD.begin() call, this is not documented in the SD_Test example.
