ESP32-S2: Getting this error while running the SD card demo 'SPIDevice' object has no attribute 'spi'

[eddieespinal]

Hi there,

I'm currently testing a new board that uses the ESP32-S2 and has an integrated SD card. When I try using one of the existing board from the website it works fine but when I flash it with my own board definition the SD card won't work and I get the following error message:

Traceback (most recent call last):
  File "code.py", line 16, in <module>
  File "adafruit_sdcard.py", line 101, in __init__
  File "adafruit_sdcard.py", line 122, in _init_card
  File "adafruit_sdcard.py", line 110, in _clock_card
AttributeError: 'SPIDevice' object has no attribute 'spi'

This is the code I'm trying to run:

import time

import adafruit_sdcard
import board
import busio
import digitalio
import microcontroller
import storage

# Use any pin that is not taken by SPI
SD_CS = board.SD_CS

# Connect to the card and mount the filesystem.
spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
cs = digitalio.DigitalInOut(SD_CS)
sdcard = adafruit_sdcard.SDCard(spi, cs)
vfs = storage.VfsFat(sdcard)
storage.mount(vfs, "/sd")

# Use the filesystem as normal! Our files are under /sd

print("Logging temperature to filesystem")
# append to the file!
while True:
    # open file for append
    with open("/sd/temperature.txt", "a") as f:
        t = microcontroller.cpu.temperature
        print("Temperature = %0.1f" % t)
        f.write("%0.1f\n" % t)
    # file is saved
    time.sleep(1)

The output of my terminal after running: make V=1 BOARD=atmegazero_esp32s2 flash PORT=/dev/tty.SLAB_USBtoUART is:

What am I missing?

Thanks for your help

I think this is a bug on our end. I believe beta.0 should work in the meantime.

Thank you for the response @tannewt, that explains why this build worked adafruit-circuitpython-unexpectedmaker_feathers2-en_US-6.2.0-beta.0.bin but not if I compile it using make for the same board.

I will give it a try with beta.0 and see if that helps.

Thanks again!

@tannewt you were right, that was the problem. After trying again using the branch 6.1.x everything works fine now.

Thanks for solving my problem.

I get this same error on both ESP32-S2 and Raspberry PI pico, but works on Seeeduio Xiao with same version of CP

I think the Xiao works because it uses the python version of bus device. The other two have it built in.

Hello, I'm seeing this error on PyCubed board in both 6.2 and 7.0 Alpha 1 versions of CircuitPython, any ideas? Thanks!
Edit: I do not see this behavior in version 5.0.0

@polygnomial Make sure you have the latest version of the SDCard library. IIRC we stopped using the .spi property from the SPIDevice class.
