Hello, where can I find the factory test program for the New M5Core3? I am very interested in the cam Part of the software.

Hello,

I would like to start a few debug commands via the console. To do this I have to read the first serial port and not block the program.

The following command does not block, but nothing is read in and the error message "Multiple decode errors occurred: Try checking the baud rate and XTAL frequency setting in menuconfig" appears.

setvbuf(stdin, NULL, _IONBF, 0);
c = fgetc(stdin);

I use ESP-IDF 5.1 and the the "M5Dial-UserDemo" as base.

Hello,
I worked with a M5Stack, Arduino 1.8.x and MacOS Mojave and every thing with USB was fine.

I updated to MacOS Catalina and updated Arduino to version 1.8.10. Every with USB for my M5Stack was fine, too. If I check the USB driver I can see:

$ ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port	
/dev/tty.SLAB_USBtoUART	
/dev/tty.usbserial-017D2264

If I like to flash my M5Stick-C and I connected it, I can see only this:

$ ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port	
/dev/tty.usbserial-9D5AE08545

With the old and the new Arduino-version the "tty.usbserial-9D5AE08545"-driver did not work. Arduino needs a "SLAB_USBtoUART"-driver.

What can I do?

Yes, I know today Catalina is a beta-version, but it will released shortly.

@lukasmaximus Thank you for your help. In the meantime I tested with Catalina Version 10.15.2 (19C57) and with the drivers from FTDI. I can not program the M5StickC, but the Arduino Monitor did work!

I found the problem: The M5StickC didn't change to upload mode!
I connected a small button between GND and G0 at the 8-ext Pin connector and I pressed the button if Arduino like to upload ("Connecting........_____...."). The workaround worked fine.
