1. RTOS-based bootloader

    - He uses serial ROM bootloader. NO RTOS-based firmware images operate after downloading through the ROM bootloader, but RTOS-based examples do not.     

We don't have any bootloader example with RTOS.

2. Example for DMA

Please go through the Help_topics for TMS570LC43X controller in HALCoGen. There you can find couple of DMA examples with detailed step by step process

If needed you can also refer below DMA examples created by me

3. Frequent interrupt handling

    - Customer's system use many communication interface so the main process cannot be performed due to frequent interruptions.

      In this case, how should I handle the interrupt?

If you are getting frequent interrupts, in that cases it would be better to use DMA to reduce the burden on the processor. So, the processor may not necessary to go each time the interrupt occurs.

For example, if you are getting frequent interrupts from ADC channels in that case use DMA to transfer ADC data to one buffer and after transferring several samples by DMA then the processor can go to the data and can perform the operations. In this mean time of DMA transfer the processor can execute the main loop.
