Issue while porting code on DSP BIOS 5

Other Parts Discussed in Thread: TMS320F28335

Hi Friends,

                    I am doing McBSP interface with DMA on DSP BIOS on TMS320F28335.Without the BIOS the code is getting proper interrupts for DMA data transfer but when i am trying to use it with DSP BIOS 5 i am not at all getting interrupts.While porting on DSP BIOS i have taken care of configuring inetrrupts with dispatcher.I have also removed keyword interrupt as per DSP BIOS configuration.After this all necessary configuration also i am not able to get any interrupts.

Please suggest me to solve this problem.

Thanks in Advance.

    Can you check the IMR register and make sure that the interrupt has been enabled?   If the interrupt is on the PIE, then you need to enable the interrupt for the PIE as well.

    The following app note might be useful:
