Hello,
I tried to upload my custom flight controller in px4.
When I just build&deploy the px4 simulink app to pixhawk board, It worked well.
However, when I tried to log some of signals in SD card using 'To Workspace' Block, some error occurred.
When I check the box 'log on MAT file' and press the button Build & Deploy, (after Limiting data point using below command)
px4PrepareModelForMATFileLogging('My File name')
It suddenly starts to Re-running CMake File with under error

### Build procedure for untitled aborted due to an error.
Error(s) encountered while building "{My File Name}"
Red letters are due to wrong encoding.
Actually, sometimes there are same errors when I tried to upload my custom flight algorithm regardless of the choice of MAT File logging(Don't know why error occurred yet).
If error occurred, I just copy the content of simulink file and paste it to new file. And it worked.
However, when I tried to upload different flight control algorithm (which is quite complex than before), copy and paste to new file doesn't solve the problem.
I unchecked the MAT File logging and upload it, and it worked but when I checked it, above error occurred so I concluded that checking MAT File logging is the reason.
I searched some related error, and speculated some problem related to file path, but not sure.
I re-build the PX4 Firmware in initalize process, but above error still occurred.
Can You give me some reason why that error occurred and solution?
Thank you very much
