The string you've inserted looks unencrypted, just garbled a bit by not fully matched transmission parameters.
The strings match to messages within the flight controller firmware. Looks like all the messages which go to flight log are also sent to the serial port.
ive tried alot of different parameters only thing i could get any english on was 115200 8n1 what do you suppose i do. i see in the ubifs drivers for a pl2303. i cant send any break commands or any command for that matter though that usb port.
Maybe there's parity in the transmission. But first we need to gen an ungarbled output, then we may look into input.
Maybe try 7n2 ?

could i look into the ubifs and check what the settings are for the console. or do you have any way to verify them?
Most upper case chars (codes 65-90) are OK. Same with numbers (48-57). Lower case (97-122) - there are issues with k, l, n, o, r, t, u; but no problem with a, b, c, d, e, f, g, h, i, z. if not the "z", I would say there are issues with ASCII codes above 106. Example - string:
"[ha_dfa+++]:******************chec+ fa+++ i+f- a+d +ace ************"
Should be:
"[hardfault]:******************check fault info and trace *******"
Pleae note, these messages come from the flight controller, not from Ambarella. The flight controller doesn't use UBIFS.
how did you do that. im using secureCrt. your very good observing the details.
You can disassemble it from P3X_FW_V01.07.0060_mi01.bin - the only unencrypted one. It can be converted to ELF by arm_bin2elf.py, then it's easy to open it with IDA Pro.

Looks like text messages are wrapped into some some kind of binary container which starts with "U".
They are still readable, but it seem likely that since output is binary, the input also needs a specific binary format to be accepted (assuming that there is support for input).
elftools - the error message should explain what to do.
i assume im looking at it right but i still have no idea how to disassemble somthing like this. i wouldnt mind the flight data usb port being turned into a serial port to the flight controller. have you tried anything like this.

What is it gona take. i think my overall goal is to make this thing faster
i see from the flight controller the speed settings are just numeric values .
This no longer seem related to serial port.
For reference - could you describe what you did to achieve the serial transmission in PuTTY?
in putty i just used 8n1 no flow control and 115200. putty had encoding set to utf8 somthing i couldnt change with securecrt.
i still want to enable the serial connection i just dont know where to start. can the components be communicated with through the gimbal. or do you have a know way to communicate with the flight controller through the usb on the front.
id like to add that i notice the drone dont even start booting untill i open the console connection, it sits there and the gimbal makes some noises and then when i hit enter to start the connection the noise stop and it start with all the booting process???!?!?
not sure what to make of this. this is digdat0s log

Regarding the log:
> invalid flash key![0]
This is harmless. I do not know what the flash key is, but when it's invalid, "airport limit" is disabled - so this seem to just inform that NFZ control is off. Might be interesting for some people, but not the reason of the drone not working.

This looks like the reason of the failure.
