The example of SPI is not communication on maixduino. https://github.com/sipeed/MaixPy_scripts/blob/master/hardware/demo_spi.py

Maixduino communication is follow,

K210-IO Function ESP32-IO Function
IO25 SPI_CS IO5 SPI_CS
IO26 SPI_MISO IO23 SPI0_MISO
IO27 SPI_SCLK IO18 SPI0_SCLK
IO28 SPI_MOSI IO14 SPI0_MOSI
IO09 GPIO IO25 ESP32_READY
IO08 GPIO Dedicated pin ESP32_EN

direct use pin as parameters and try again ?

like:

spi1 = SPI(SPI.SPI1, mode=SPI.MODE_MASTER, baudrate=10000000, polarity=0, phase=0, bits=8, firstbit=SPI.MSB, sck=28, mosi=29, miso=30, cs0=27)
