Other Parts Discussed in Thread: LAUNCHXL-F28379D, CONTROLSUITE

Hello,

For a H bridge inverter application, when i try to port my code from LAUNCHXL-F28377S to LAUNCHXL-F28379D, ePwm frequencys of LAUNCHXL-F28379D are half of what i used to see at LAUNCHXL-F28377S ePwm frequencys. İ did not change any variable in my code. Is there any clocking difference between there two boards.

And also, for LAUNCHXL-F28379D when i build my code with compiler version TI v.6.4.10 there is no problem, but when i build my code with TI v.15.12.0LTS to 15.12.3LTS, i get 10 warnings, #10190-D.

Thank you for your help

Hi,

Both device have same clocking limits. If you are using external OSC, check the frq of these OSC on both the boards. It might be that external OSC frq is different on these boards.

Hello Vivek,

I am using launchpad boards and i did not change anything with the hardware. I am using below project

thank you

Make sure you have the predefined symbol "_LAUNCHXL_F28379D" and note usage in F2837xD_SysCtrl.c which also affects SCI baud rates, etc.

#ifdef _LAUNCHXL_F28379D
InitSysPll(XTAL_OSC,IMULT_40,FMULT_0,PLLCLK_BY_2);
#else
InitSysPll(XTAL_OSC, IMULT_20, FMULT_0, PLLCLK_BY_2);
#endif // _LAUNCHXL_F28379D
