busdevice setup/init not working on 6.1.0 w/ CLUE nRF52840

[siddacious]

Using the following test code and a SGP40 attached to the CLUEs Stemma QT port,

import board
import busio
import adafruit_bus_device.i2c_device as i2c_device

i2c = busio.I2C(board.SCL, board.SDA)
i2c_device = i2c_device.I2CDevice(i2c, 0x59)
print("i2c_device 'found'")

with 6.0.1 I get:

with 6.1.0 Beta 2 I get:

The only change here is flashing the new version

Interestingly, an I2C scan works as expected with 6.1.0 Beta 2:

Maybe this is a dupe of #3795, fixed by #3847. But we are disabling native busdevice for now due to other issues: #3869.

You could test against the artifacts from #3847. For the CLUE, try https://adafruit-circuit-python.s3.amazonaws.com/bin/clue_nrf52840_express/en_US/adafruit-circuitpython-clue_nrf52840_express-en_US-20201218-fd21ff5.uf2. That is the #3847 merge commit, and is before #3869.

@dhalbert looks the same with the uf2 you linked to:

Hmm, that's not what I expected. Could you also try the absolute latest from here: https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/clue_nrf52840_express/en_US/

[siddacious]

@dhalbert I tested the latest and it seems to work.

I tested the previous (d21ff5) again as well and confirmed the failure.

Lmk what else you'd like me to try

OK, great! So let's close this for now, and we'll make sure to retest when we get around to putting back native bus device.
