Hello,
I am new to SYS/BIOS and I want to port the Starterware example: C:\ti\am335x_sysbios_ind_sdk_1.0.0.8\sdk\starterware\examples\evmAM335x\mcasp\ which is running well on my beaglebone board to SYS/BIOS. I am somewhat confused how to setup the edma and Mcasp interrupts/events and what part of the initialization code can be removed - I assume, that the SYS/BIOS takes care on that. I have done the setup as learned by the training sessions from "Eric Scott". See below for details on the config file. However, I get an exception in the edma module. Any idea what could be wrong ? What about the priorities? I can hear that the McASP0 is correctly initialized (noisefloor is audible).

1.) Interrupts correctly set?
2.) What about the Event id fields ?
3.) What about the Interrupt priorities?
4.) Which parts of the initialization is taken care by the SYS/BIOS, when registering a hwi for a certain interrupt ?
5.) Where should the I2S AudioLoop (copying the paramsets) be located (was in the main loop of the example) ? Should it have an own task ?
