Problem with F280049 and ePWM module


Hi!
I can not use the F28x ePWM module with the microcontroller F280049M
This is a basic module! With the F2808 and other uC it works well
This is the only uC model that is having conflicts with this module
I am getting this error:
C:\Altair\Embed2019\cg>lnk2000 --display_error_number --diag_suppress=16008 -c -x -q -mPWM_with_Phase_Shiftv2.map PWM_with_Phase_Shiftv2.obj -l lib\SFO_TI_Build_V6b_fpu.lib -l lib\vsrtos_F280x_fpusr.lib -heap 1024 -stack 512 -o PWM_with_Phase_Shiftv2.out lib\F280049flnk.cmd

Thanks for your help!
