Hallowing M4 no longer works

Post by MichaelNightmare1 »

When my Hallowing M4 arrived, it worked great out of the box. I changed a parameter in the config.eye file, and it went blank. I have updated the bootloader, and dropped adafruit-circuitpython-hallowing_m4_express-en_US-7.3.3.uf2 onto the HALLOM4BOOT drive, and I get what appears to be a CircuitPython screen. When I drop HALLOM4EYE.UF2 onto the HALLOM4BOOT drive, I get an infinitely flashing orange LED, but still no eye.

Yes, installing CircuitPython will give you CircuitPython. The eye code is written in C++, not CircuitPython.

What did you change in config.eye?

I changed the "eyeradius" to 150, but didn't realize it until after I had saved it.

Does it work if you put the original back?

No. After I tried that, I started looking for a solution on the internet, but still no eye.

I can't see making a config change causing it to completely fail like this. I suggest deleting (and emptying trash) everything off of CIRCUITPY, reinstalling the EYE firmware and re-copying the data files.

I tried deleting the files & emptying the trash, but when I double tap the reset button, and drop HALLOM4EYE.UF2 onto the drive, I get an infinitely blinking orange LED.

Did you copy over the eye data files?

I can copy them over while the Hallowing M4 is running CircuitPy, but when I double tap reset and drop the HALLOM4EYE.UF2 file onto the drive, I get the flashing LED & the unit no longer shows up as a drive.

Oh. Well, that's significant. CIRCUITPY should still show up!

The yellow/orange LED is part of the charger. It will flash/flicker if there's no battery connected. As noted in the guide:
The charge LED is automatically driven by the Lipoly charger circuit. It will try to detect a battery and is expecting one to be attached. If there isn't one it may flicker once in a while when you use power because it's trying to charge a (non-existent) battery. It's not harmful, and its totally normal!
Have you tried running the diagnostics code? https://learn.adafruit.com/adafruit-hal ... cs-3042541

How can I view the output from the diagnostics code?

I believe it displays on screen, if not then over serial/usb.

No output on the built in display, I tried to view it in the Arduino serial monitor. It connects, but I can't get it to output any info.

To double check. When you install CircuitPython, it resets, CIRCUITPY mounts, and you get the snake and CircuitPython output on the onboard screen?

Yes, exactly.
