AWR1642: The problem about CallbackFxn() on DSS.

Xiao Du

Part Number: AWR1642

I created two dss project called DSS_PBL and DSS_APP , the DSS_PBL is a project without RTOS ,it 's function is simply to jump to 0x007E1000 ( the code of project called DSS_PBL was stored in 0x007E0000-0x007E1000 ,and the other project called DSS_APP is similar to demo of DSS,was stored in 0x007E1000 - 0x007E1000 + 0x0003f000 .

But now , I have a problem , when the DSS has executed DSS_PBL and then jump to 0x007E1000 ,the MSS code also is running ,DSS can not go in any Callback function like MmwDemo_dssMmwaveConfigCallbackFxn() or MmwDemo_dssMmwaveEventCallbackFxn() , So , can you tell me what caused thr problem ?

Hello Anist,

For DSS application default interrupts vector table location is on 0x007E0000. Which in case of DSS_APP is lost in context, because of which DSS_APP is not able to call any callback functions.

To resolve this DSS_APP image should have interrupt vector table map to DSS starting memory i.e. 0x007E0000. so that each interrupts event can invoke corresponding callbacks.

Jitendra Gupta

Hello Jitendra ,

In my DSS_APP , the interrupts vector table is on 0x007E1000 ,like this

although for DSS_PBL the default interrupts vector table location is on 0x007E0000 ,there are also interrupts vector table on 0x007E1000 for DSS_APP , if the code jump to 0x007E1000 ,it still can not call any callback functions?

I figure out that the DSS_APP code can‘t go in MmwDemo_dssMwaveConfigCallbackFxn() was because of the mailbox did‘t work well .

The DSS_APP code has problem in "Semaphore_pend(gMmwDssMCB.mboxSemHandle,BIOS_WAIT_FOREVER)" and "Mailbox_readFlush(gMmwDssMCB.peerMailbox)" , So the MSS didn't configure the BSS successful .

What's the problem with the Mailbox ?
