HALCOGEN: HALCoGen FREERtos template doesn't allow to set up 1-3 rti compare lines.

Part Number: HALCOGEN

Hi.

I'm using HALCOGEN TMS570LC4357ZWT_FREERTOS template. This template has full control over rti module and doesn't allow to setup 1..3 compare modules, which aren't used by RTOS kernel. I didn't find any clean way to setup any of left compare signals, it cannot be done by user function before because of non-OR expression:

/* Enable the compare 0 interrupt. */
portRTI_SETINTENA_REG = 0x00000001U;

I guess that it can be done in user defined rtos thread but it is not best way. Why HALCOGEN disables 1..3 rti compare signals?

it cannot be done by user function before * calling vTaskStartScheduler();* because

Hello Andrey,

You can add other RTI compares to prvSetupTimerInterrupt() function.

Hello.

Thanks, yep, i'm using this way right now, but prvSetupTimer() is auto generated function, and it has STATIC keyword that makes impossible apply WEAK approach (may be i'm wrong with it, but i've tried and with static keyword weakness ignoring). In my case i set up readonly attribute on os_port.c file for disabling rewriting when halcogen code generation performs.

HALcogen developers may pay attention to this moment in future releases.
