Adafruit_Blinka: OSError running sample script for MCP3008 on Libre Computer aml-s905x-cc "Le Potato"

I am running into an OSError trying to run sample code for MCP3008 on the Libre Computer aml-s905x-cc “Le Potato”. I have made slight changes to sample code, changing the pin numbers, putting the print statements in a loop, and I’ve tried busio and extendid bus with the same results .

Here is the script I am trying to run:

import time
import busio
import digitalio
import board
import adafruit_mcp3xxx.mcp3008 as MCP
from adafruit_mcp3xxx.analog_in import AnalogIn
from adafruit_extended_bus import ExtendedSPI as SPI

# create the spi bus
#spi = busio.SPI(clock=board.P23, MISO=board.P21, MOSI=board.P19)
spi = SPI(0, 0)

# create the cs (chip select)
cs = digitalio.DigitalInOut(board.P22)

# create the mcp object
mcp = MCP.MCP3008(spi, cs)

# create an analog input channel on pin 0
chan = AnalogIn(mcp, MCP.P0)

while True:
	print('Raw ADC Value: ', chan.value)
	print('ADC Voltage: ' + str(chan.voltage) + 'V')
	time.sleep(5)

Here is the error:
