Compile i6X

[AGATTTTT]

Hi, I'm trying to compile an erfly6 project for a flyskyi6x radio with SEGGER and I'm getting an error about undeclared parameter.
Boardi6x.cpp line 756:

Building ‘FSI6X’ from solution ‘ERFly6’ in configuration ‘Debug’
Compiling ‘lcd.cpp’
Compiling ‘BoardI6X.cpp’
use of undeclared identifier 'ISR_TIMER3_CAPT_vect'
Build failed
Compiling ‘A7105_SPI.cpp’
Compiling ‘AFHDS2A_a7105.cpp’
Build failed

Can anyone help me how to solve this?

For i6 radio I have this error different:
