@felmue Interesting, I just read that sometimes SPI devices clash and cause issues.

ahh, its an spi device so will have issue with the internal spi screen.

There is an Epaper M5stack device in development but you would be better off with this device

If its and i2c screen then you can connect it to Port A otherwise you will need to use the 2x15 internal bus connector.
if programming in arduino, there are librarys available to install but for the stock firmware then it will be alot harder to use.

10.10.5?
I'm running 10.14.2 (mojave) and can program using UIFlow and arduino.
It could be that you OSX is too old to support it.
Have you installed python3 ?
what is the error message that the updater returns?

@dpharris

in this page you could choice the program platform. and click the category card view the Quick Start.

https://docs.m5stack.com/#/en/quick_start/atom/atom_quick_start

@ardo Yes, you could connect they together.

feed power to the bus connection inside the m5stack (2x15 pin connection) as long as no battery is connected then that should work as you need.

@ruvic101

use the last version firmware. （you could find it in this page :https://docs.m5stack.com/#/en/quick_start/m5stickv/m5stickv_quick_start）

also , for the time being the yolov3 function is unstable . even you loading success the model and runing. It may still happend memory not enough
