Which betaflight version are you using? I can only test with betafligth 3.5 due to hardware limitations.
Is everything working as expected on your PC with a USB connection? The error only appears on the Raspberry Pi with a serial connection? Can you specify what is working and what is not working on your PC and on the Raspberry Pi?
The "box names" are unrelated to the MSP RX functionality. From your logs (please provide raw text instead of screenshots), I can only suggest that there is a transmission error.

Thanks for reply. I'm using Version 4.1.1. client_read_test working as expected both on raspberry's UART connection and PC with USB connection. fcu_motors and fcu_test throwing the boxNames error.
When running client_read_test on PC with USB the output:(./client_read_test /dev/ttyACM0)

If you check the message definitions at https://github.com/christianrauch/msp/blob/master/inc/msp/msp_msg.hpp, you can see that the IDs 112...116 are related to the "box" names and their values. Maybe these messages are just not supported anymore on newer firmware versions, or their definition changed.
The reason why the "client" examples work and the "fcu" examples crash is that the FlightController class requires the boxes to check the flags, such as if the FCU is armed.
If there is now another way to check the arm state of the FCU, I am happy to review A PR that replaces the boxes with this.

Actually I don't know the structure very well but I tried to check IDs which are you said. What I did may be ridiculous but if you check I will be very thankful. First of all I clone the latest Betaflight from it's offical github. And with grep command in Linux terminal search for message definitions. Like this:
grep -r "MSP_BOXNAMES"
inc/msp/msp_msg.hpp: MSP_BOXNAMES = 116,
inc/msp/msp_msg.hpp:// MSP_BOXNAMES: 116
inc/msp/msp_msg.hpp: virtual ID id() const override { return ID::MSP_BOXNAMES; }
And I did this for each message definition. IDs are same as you defined. That has a meaning ? If there is a estimated solution could you please say me what should I search?

Hi I was looking for understand the code. Actually I'm not using C++ but I can understand the functions. I decided to understand error messages respectively. I started with;
"Message marker 82 is not recognised!"
First of all I changed the if statement which checking the message marker first byte and decide v1 or v2. And I printed all bytes of response message with a for while in this if statement (After line 299 in Client.cpp). After find the decimal values I translate them with a calculator and I found this message:
79 76 59 83 84 73 67 75 32 67 79 77 77 65 78 68 83 32 68 73 83 65 66 76 69 59
"OL;STICK COMMANDS DISABLE;"... It can be related with my problem ?
Could that be the reason why we didn't get box names right?
I'm only trying to understand code. I hope I'm not bothering you in the meantime. If so please warn me.

Problem is solved :) Thank you very much for your helps and source. Actually I'm not changed anything in your code. I guess I were loaded false firmware which I customized for try other solutions. I can arming the quad from pc on USB and from raspberry on UART two of them working. Thanks again.

This looks like names for what used to be in the "boxes".
Problem is solved
That is good to hear.
I still don't know what caused the original problem, but if you could solve it on your side you can close this issue and reopen it in case the problem comes up again.
