M5StickC/ATOM on MacOS Catalina can't upload/ ESP32: Timed out waiting for packet header solution (Solved)

@cepics you could try setup the baud to 115200. then try again. or contact our store. we will help you solve it. as soon as possible
no way!!! Atom serial port doesn't appear in the serial port list..... more than one cable tested....
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?

My new m5stick-C are showing up on the MacOS (10.15.3) as M5 Serial Converter, and in the Arduino IDE (latest edition). I have applied the updater as suggested in this thread, and still get this response when trying to upload from the IDE to the device: "fork/exec /Applications/Arduino 2.app/Contents/Java/tools-builder/ctags/5.8-arduino11/ctags: bad CPU type in executable
Error compiling for board M5Stick-C."
@rschdev clearly. this is a compiling error . you should check the error information , and check you program.
@herrlehmann did you installed the FTDI driver? you could try delete both below files. then connect your device try again.
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.
@m5stack did you dig any deeper into this? 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:
Hersteller-ID: 0x0403 (Future Technology Devices International Limited)
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.

@nsfilho don't update to 10.15.04....
@m5stack : Yes, I did. 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.

@climbingrose I have same problem. Have you found any solution?
@finnsen if you try these solution still can't solve the problem. you could contact the store
@m5stack What do you mean by contacting the store, how can they help me resolve the issue? Or do you mean to return the product?

@finnsen I didn't catch what you were trying to flash to your device, if you are trying to update uiflow firmware on the device with M5Burner and it fails, have you tried using esptool to flash firmware? if you were uploading an arduino program there are known issues with all esp32 devices on catalina not just m5stack https://github.com/arduino/Arduino/issues/9438 I did make a video a while back ( https://www.youtube.com/watch?v=MTCjKhVKOto) about using m5stack devices on catalina and I didn't seem to come across any of the issues you mentioned, perhaps the issues are with a later revision of catalina, I'll update and take a look when I get chance.

@finnsen I mean, If above these solutions still cannot be solved, even if change the computer system(use win10) , use the different flash tool, setup low upload speed(baud 115200), it cannot be solved, then there may be a product problem. 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
@lukasmaximus Thank you for your video. I did not know about setting the device in USB mode as you video explained. I am now getting things to work. Thanks. :)
@m5stack My issue where not knowing about setting the Atom Lite in USB mode. 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.
@m5stack: I finally fixed "my" problem being not able to "see" the Atom Matrix on a mac with 10.15.x!!! 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.
