Kaluga not connecting via USB (since esp-idf update?)

[jepler]

I am using the uf2 bootloader (0.4.0) installed with Adafruit ESPTool.

Firmware downloaded from s3 and installed via uf2/KALUGA1BOOT:
adafruit-circuitpython-espressif_kaluga_1.3-en_US-20210625-5a4a803.uf2

Behavior

With the above named firmware version, the CIRCUITPY drive does not appear. The LEDs do blink, so CircuitPython appears to start.

Linux dmesg shows errors like device descriptor read/64, error -110

Reverting to adafruit-circuitpython-espressif_kaluga_1.3-en_US-20210625-d67fb85.uf2 from s3 works

I think this indicates the problem was introduced by #4195

I did not test any other boards or installing via .bin.

@askpatrickw you may be interested in taking a look.

@jepler i'm away from my desk for a few days. But I do have a Kaluga and can try to repo next week.

Does the .bin work?

Using the .bin , mine boots but goes in to safe mode

uto-reload is off.
Running in safe mode! Not running saved code.

You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Crash into the HardFault_Handler.
Please file an issue with the contents of your CIRCUITPY drive at

ah -- but it is OK if I remove my old code.py (using the OV7670 demo code from a few weeks ago

My device (probably) had an OV____ camera demo on CIRCUITPY too, fwiw.

I also have a magtag with uf2. 6.3.0 works, but adafruit-circuitpython-adafruit_magtag_2.9_grayscale-en_US-20210701-37c5211.uf2 apparently goes into a bootloader loop, blinking purple on all LEDs once, then yellow/orange on the first led 4 times, then blinking purple on all LEDs forever.

At Dan's suggestion I was going to try wiping the uf2 bootloader and try with a bare "bin" file, but I had trouble with esptool (related to the computer I was using, probably) and didn't get that far.

When I copy the .UF2 adafruit-circuitpython-adafruit_funhouse-en_GB-20210701-37c5211.uf2 to my funhouse the dotstars flash purple. Doesn't happen with the 7.0.0-alpha.3.

[rsbohn]

I can then go into boot mode and install 7.0.0-alpha.3 (tries to run code.py, fails because I haven't updated the libraries yet).

I tried the latest builds on a Metro ESP32 and a Feather S2. Without a code.py, they come up and I can use the REPL.

I had a random test program on the Feather S2, and found that this simple program causes a crash:

import busio
import board
import displayio
import adafruit_il0373

displayio.release_displays()

spi = busio.SPI(board.SCK, board.MOSI)
epd_cs = board.D9
epd_dc = board.D10

display_bus = displayio.FourWire(spi, command=epd_dc, chip_select=epd_cs, baudrate=1000000)

The last line causes a crash. If I remove the displayio.FourWire(), there is no crash.

I didn't actually have a display attached, but it doesn't matter: the display is output-only.
