I opened the box!!
There's a connector which can possibly be the wifi module connector, as is a tipical TX/RX/rst etc connection diagram, so i will connect a bluetooth module and see what happen :zap:

Be careful. The port is 3.3v. However i only measured 3 volts on the uart. Maybe it is 2.8v? The oscilloscope told me a peak voltage of about 3v for tx.
Sending data does not seem to work.
The external uart is just for the mpg, but I could spawn a console there.
The bootlog can be found a few posts back.
I doubt we can get into the bootloader but i am going to try it anyways.

:coffee: How strange, the "G53" coordinate command is mentioned in the "english" configuration file, but in someway is hidden in the running program, as normally is the "safe" coordinate for the manual tool change if any for the older CnC.
Then i do not find any reference to the "Enable M-Bus I/O command" and "M-Bus I/O default status" ...... :palm:
There's a BIG mistery in this controller.
Work in progress.

Another strange thing regards the linuxrc file.
It is just a symlink to busybox located in /bin
However i doubt deleting it would cause any harm, as I think it is just a ram file system.
Don't quote me on that though yet.
This also means, you can delete any file and it will not cause any harm a firmware upgrade can't fix.
However this also means we can't easily get rid of the original splash screen entirely.
I am starting to wonder if the default splash is located in the busybox binary.

If anybody wonders, we have got 32 MB RAM and the following CPU:

--- Code: ---Processor : ARM926EJ-S rev 5 (v5l)
BogoMIPS : 95.64
Features : swp half thumb fastmult edsp java
CPU implementer : 0x41
CPU architecture: 5TEJ
CPU variant : 0x0
CPU part : 0x926
CPU revision : 5

Hardware : W55FA93
Revision : 0000
Serial : 0000000000000000

--- End code ---

Also I found out there are drivers for a tty on the scren available.

So, basically the tty is set up at 115.200 baud? and for what? to communicate between the cpu and who?...... :bang:
