Not able to connect the OpenIMU300ZA EVK to the developers console in Ubuntu

I am currently using openimu300za EVK in Ubuntu and installed all the pre-requisites as mentioned in the device connection procedure. I am connecting to server using the server.py file which i downloaded from github. Could see the terminal giving some messages continuously after running the python file. But unable to connect to developer's console, as the device is not getting detected in console. Getting messages as shown below in the terminal.

Please suggest if something is wrong or should i need to do change anything?

chmod 777 ttyUSB0 and try, you need change the USB device file access right

Yes have tried that, but still getting the same.

try root account

No luck. Still unable to connect. Just to inform, at starting when the kit was powered up, i was able to see 2 LEDs glowing, LED2 and LED3. But after that i downloaded the example code from "https://developers.aceinna.com/code/apps" named "OpenIMU300 IMU Application" and flashed that code into the kit using ST link debugger. After that i could see only LED3 glowing(the red one), so is there anything problem with the code or kit?

which start address used when you flashing? did you saved your original EEPROM(FW, Calibration data and so on) data firstly?
if not, It has been brushed to death i doubt.
pls tell me:

1. current your status
2. how did you flashed? steps
3. backup your FW or not firstly.

1. Currently have flashed the basic IMU example given in the aceinna extension in visual code.
2. During first time, followed below steps,
   • Connected IMU to ST-link and opened STM32 ST-LINK Utility application
   • Loaded the image file downloaded from Aceinna Apps
   • Clicked on Target in STM ST-LINK 32 and then clicked on program & verify and started flashing.
3. Haven't taken the Backup manually

when you started flashing which start address used? what is your SN number?

Sorry haven't noticed that
