TDA3XEVM: some questions bout all eve- to- dsp communicaition in starterware mailbox example

hi,Anshu

I have checked the original code of mailbox_dsp1_all_eves example. in TI sdk.

 i didn't find the part of code that each eve(4 eves) writes to dsp, the code is just the same as sigle eve-to-dsp communicaiton example

hi,Anshu

i  have checked what you mentioned. It is stated as follows:

"

This example is specifically meant to be run only Vision28 Super (vayu) platform, the reason being
this example requires multiple EVE’s (in this case 4 EVE’s). All the interrupt and mailbox
configurations are similar to above examples. From EVE side, each EVE will write into mailbox for
DSP. On DSP side, DSP will get interrupt from each EVE and will keep incrementing a count. DSP
will wait till it gets interrupt from all the four EVE’s. DSP will keep on acknowledging interrupts
from EVE mailbox module by writing message back to mailbox. Once it receives interrupt from all
the messages it will return PASS value.
Note: While building mailbox example make sure you give proper PLATFORM name for Vision28
Super(vayu) "

however, what the datasheet states is not consistent with the oringinal code. I have not found the code that each  each EVE will write into mailbox for DSP.

The code of the eve sender is just the same as sigle eve-to-dsp communicaiton example .

Anshu:

ok .i get it

Thanks
