@nishad2m8 Nice work and well done writing it up.
Thank you.

@mgrouch I don't have the slightest idea.
I run the apt update and apt upgrade to make sure I have the latest version.

@nishad2m8 Can you write up a guide on how you made this and post it to hackster.io please?

@WigglerAway You will need to check out the documentation on the M5Stack website for the exact pins but by default UART1 is broken out to the blue port and UART 2 is broken out to the MBUS connector.

The CoreMP135 has UART1 broken out to the blue port, UART2 to the MBUS and UART6 broken out to the RS485 connector.

@bobkummerfeld You need to grant permission to M5Burner to run.
Apple changed the security to prevent none App Store apps from running and so you need to manually permit access.

The process is a bit confusing so please google how to permit none approved apps from running on Apple M1 based computers.

@leo-ninja-turtle Have you installed USB drivers?
Are you using a working sync cable?

@Phil_C In all honesty its actually telling you what's wrong.
What part or the messages are you not understanding?

@mgrouch There are many ways.
My current method is to use Lego technic plates but there are 3d printed mounts or on boards.

@mgrouch How do you mount what in an "presentable aesthetically pleasant way"
You haven't provided enough information or pictures of what you are tying to mount or what you have tried so far?
