1170 EVK audio examples on Maaxboard RT

samr2

Hi,
I have difficulties running 1170 EVK audio examples on Maaxboard RT. I followed general guidelines on users guide v1 but still failing. Could you please advise any other guideline or working examples on maaxboard rt?
it's about running edma/interrupt transfer audio examples on  maaxboard rt.
Cheers, 

  • Hi Samr2, 

    You can find a few fully functional demos/examples for the MaaxboardRT at the Avnet Github MaaXBoard-RT-V3--Projects. If you are interested in audio I would recommend looking into the Maestro demo. 

    If you are just trying to migrate the 1170 EVK demo over to the Maaxboard RT make sure that you change out your flash memory configuration file (.cfx) out from the EVK targetted one since the MaaxboardRT has hyperflash. This is documented in section 6.6.3 of the Maaxboard user guild. 

    At this time we are still working on finishing our supporting MaaxboardRT SDK which will enable you to export examples directly from MCUXpresso. 

    What type of errors are you having? 

    Jason

    Hi Again,
    My problem continues here, I tried setting/config on Maestro example along with Users guide guidelines to make an evk1170 example working. I can send the project to you and I'll appreciate if you could take a look.

    This is the error message I'm getting :

    Program stopped.
    0x3000ac36 in HardFault_Handler () at ../source/semihost_hardfault.c:61
    61 __asm( ".syntax unified\n"

    Temporary breakpoint 1, main () at ../source/sai_edma_transfer.c:236
    236 edma_config_t dmaConfig = {0};

    Program received signal SIGTRAP, Trace/breakpoint trap.

    Can you share which specific NXP SDK example you are using as a starting point? 

    I'm assuming that you are starting from either the sai_edma_transferr_cm7 or the pdm_edma_transfer_cm7.

    Hi Jason,
    I'm still waiting on your advise to convert sai_edma_transferr_cm7 example on Maaxboard RT.
