Define a non-bios timer interrupt function callback within a BIOS application.

Simon lapointe

Hello,

I have a BIOS application with a timer Hwi thread which is configured using XDC tools, and it works.

But I don't know which resource is configured, it's hiden in the XDC configuration and I don't know where to check what is going on before main.

I also want to define another interrupt call to a function but NOT using a thread. When I add this code, nothing works anymore in the BIOS:

rtiInit();
vimManager.Init( &UnusedInterrupt );
vimManager.SetUserInterrupt( DrvVim::VIM_RTI_COMPARE_0, DrvVim::VIM_IRQ, &_interrupt20kHz );
rtiEnableNotification( rtiNOTIFICATION_COMPARE0 );
rtiStartCounter( rtiCOUNTER_BLOCK0 );
»

Is there a way to define another hardware timer using XDC tools with no BIOS thread at all that will no interfer with the xdc BIOS configuration?

The approch I want to use is the one described here in the TI article:

http://www.eetimes.com/design/embedded/4008294/Reduce-RTOS-latency-in-interrupt-intensive-apps?pageNumber=4

My run time support library is: rtsv7R4_A_be_v3D16_eabi.lib

Target is ti.targets.arm.elf.R4Ft_big_endian

My chip is TMS570LS20216SZWT and I've got the development kit TMDX570LS20SUSB.

I don't recognize the code snippet you've provided. What is "vimManager"? Is that a 3rd party C++ library API?

Also I don't know what you mean by "define another interrupt call to a function but NOT using a thread".

Can you explain that a little more for me?
