SYS BIOS 6 HWI Initialization

Other Parts Discussed in Thread: SYSBIOS

I'm converting a C6486/C6472 BIOS 5 project to BIOS 6, but am not clear what all is required (not enough examples in docs). In BIOS 5 I statically created a HWI object in the TCF:

bios.HWI.instance("HWI_INT4").fxn = prog.extern("isrDoorbell");
bios.HWI.instance("HWI_INT4").useDispatcher = 1;

then in my initialization code I used these to map the local SRIO event number to the INT and enable IRQs:

// Enable SRIO Doorbells IRQs - INT4

Hwi_eventMap(4, CSL_INTC_EVENTID_RIOINT_LOCAL); // Optional - this is the default mapping
CSL_chipWriteReg(CSL_CHIP_IER, CSL_chipReadReg(CSL_CHIP_IER) | C64_EINT4);

Does the following accomplish all of this in a BIOS 6 *.cfg file (since Hwi_Params.enableInt defaults to True)?

var Hwi4Params0 = new ti_sysbios_family_c64p_Hwi.Params();

Hwi4Params0.eventId = 4; // RIOINT_LOCAL Event number

var Hwi_INT4 = ti_sysbios_family_c64p_Hwi.create(4, "&isrDoorbell", Hwi4Params0);

Thanks

Calvin,

var Hwi4Params0 = new ti_sysbios_family_c64p_Hwi.Params();
Hwi4Params0.eventId = 4; // RIOINT_LOCAL Event number

var Hwi_INT4 = ti_sysbios_family_c64p_Hwi.create(4, "&isrDoorbell", Hwi4Params0);

Yes, what you wrote above should accomplish what you did for BIOS 5.

Cool! It's nice to manage all of this in one place. Just wish the docs or at least SPRAAS7D - "Migrating a DSP/BIOS 5 ..." guide had more examples.

Thanks,

Calvin
