Details about EDMA3LLD memory copy example

Hi All,

         EDMA3LLD provides a memory copy example based on BIOS. I see that HWI 7-10 define 4 interrupt num0-3, and the function name is the same (ECM_dispatch). but I can't  see ISR ... So

 

1.what's the purpose of  the configuration?

 

2.In manual triggered mode, EDMA3_DRV_enableTransfer() writes to the ESR/ESRH to start the transfer. the API is declared in  edma3_drv.h,   I can't find any operation about ESR Register.  where could I find the operation?

 

3. every time I click ECM module of HWI , BIOS will not work, so  have to close BIOS module. Installiation  reason?

 

by the way, the software version is:

 

                                                                              CCS4.1.2      BIOS 5.41.02.14    EDMA3LLD.01.11.03.01 

 

Thanks
