Rfid FX9600 Embedded SKD

FX9600 Embedded SKD - Change File Permission access denied

I've created an embedded app for RFID scanner FX9600. After installation into the scanner, I am unable to start it through the http page and it seems that the files were installed without execution access.

The documentation tells me to change the files permission:
"NOTE: Ensure execution permission is provided for the binary executable, the Start and Stop script. If not, use the chmod +x command to change permission of files."
