    Hi,

    It's a bit difficult to know what the problem might be. I would recommend you to follow our software developer's guide section 9 : Development and Debugging. Please provide more information after you have exercised all the provided debug steps, so we can better assist you.

    Is hard to debug why  is a random bug but and i never have this bug when jtag is conneced

    I have found a fix but i don't like this fix

    the fix is add Power_SB_DISALLOW and Power_IDLE_PD_DISALLOW during spi transfer

    Exemple

    Power_setConstraint(Power_SB_DISALLOW);
Power_setConstraint(Power_IDLE_PD_DISALLOW);

int ret = SPI_transfer(spiHandle, &masterTransaction) ? 0 : -1;

Power_releaseConstraint(Power_SB_DISALLOW);
Power_releaseConstraint(Power_IDLE_PD_DISALLOW);

    Is there another solution?
