Other Parts Discussed in Thread: TMS320F28234
I am using TMS320F28234 , doing a sensorless vector control. While the program is working from RAM, my control loops are perfect. When I am flashing the program ripple in current are more and hence the current harmonics. I am using .asm files provided by TI for changing RAM to flash. The flash program after power up are changed to RAM using API's.
I have two observations , would like to know the reasons
1) The control loop takes 7-8us more compared to RAM. Even-though the program runs at RAM. Would like to know the reason for the same ??
2) What may cause higher current ripples while Flashing. Is there any issues in ADC while running form FLASH.
