And also your #include and setup() code. I am on mac Big Sur v11.3 and can reliably program M5StickC, StickC Plus, Atom and Fire using PlatformIO.

Running under macOS Big Sur. Trying to use the M5AtomLite

I finally got it working under Arduino IDE, being able to burn code.
The UIFlo software also works, partially. With the M5Burner I can erase and burn the UIFlow software, setting it to USB mode, and after that, it is able to burn a new program with UIFlow (using 1.7.2 beta). But after each burn, the connection gets lost and I need to go to M5Burner separately, erase the Atom and burn UIFlow again, and setting it to USB-mode.

But my prime concern is using VSCode, which doesn't work
Using Board definition pico32.

Hi, I have two M5Stick-Cs purchased in the same lot, one succeeded in updating this firmware, the other failed. The error display is as follows. Is there any countermeasure?

At first I suspected a Wacom tablet driver which interferes with my serial port, but at the end it was an old FTDI driver helper named D2xxHelper. I figured out the problem by issuing this command

sudo ioreg -lirc IOUSBHostInterface

It gives detailed information on the USB connections and its drivers. For the "M5 Serial Converter" it stated the the D2xxHelper as driver (helper). By removing this old driver and rebuilding the kernel cache I was finally able to "see" my Atom Matrix on Catalina. Enclosed my commands:

sudo rm -rf /Library/Extensions/D2xxHelper.kext
sudo kextcache -i /

After this I've rebooted my mac.

And I got confused about the USB firmware upgrade that you described in your initial post as I get the error message that the Update program is not able to set the device in DFU mode. Anyways, things seems to work. Thank you.

Please contact the store for a replacement. and, we recommend that you use the official version of the operating system, not the preview/beta version. In some preview versions, the driver will not work properly

By further investigating the driver, it looks like they are not working due to signing issues. I found this thread https://www.ftdicommunity.com/index.php?topic=409.msg1171#msg1171

I'm waiting on this rerelease, than I'll let you know. Thanks.

I'm still unable to use the M5Atom Matrix on my mac with Catalina. I started over again by installing and deinstalling stuff, but no new device appears. The system recognizes the M5Atom Matrix by naming a M5 Serial Converter with following information:

Produkt-ID: 0x6001
Hersteller-ID: 0x0403 (Future Technology Devices International Limited)
Version: 4.00
Seriennummer: 79525701B4
Geschwindigkeit: Bis zu 12 MBit/s
Hersteller: M5STACK Inc.
Standort-ID: 0x14500000 / 6
Verfügbare Stromstärke (mA): 500
Erforderliche Stromstärke (mA): 100
Zusätzlicher Betriebsstrom (mA): 0

I also applied the firmware update many times successfully.

@m5stack : Any other ideas? I'd like to play with it.

/Library/Extensions/FTDIKext.kext

I had access to a Windows machine and was able to use the easy loader on my M5Atom Matrix. It is working on Windows.

For my mac:
Yes, I installed the FTDI driver, but they did not work. I've removed them as suggested, but it didn't change anything. There is still no device appearing in /dev/, so it is not accessible.

No, the is (un)fortunately no Windows machine. I'm a little confused about the fact, that the above mentioned firmware is running without any problem. So there needs to be a connection between mac to m5atom in some way — or how is it writing to the device?
