Hi SHIBU KUMAR,

When working with Simulink External Mode in TI F28335 control card, the SW1 switch should be in the OFF position. For real-time interactive testing, the JTAG interface can be used. Serial communication is not affected by setting the switch state to off position. It allows GPIO-28 to be used as GPIO. Setting the switch to off position is mainly used in JTAG emulation.

Hope this answer helps.

Thanks,

Ravi
