CCS/RM48L952: RM48l952 Halcogen code generated with FREERTOS doesn't generate HET Low/HighLevelInterrupt notification?

Part Number: RM48L952
Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

I'm using Halcogen to generate code for CCS project. I choose the option RM48l950ZWT_FREERTOS and I try to add HET driver. the code was generate for HET the clock signal and output pin works just fine but I notice that het1LowLevelInterrupt in VIN RAM isn't generated in sys_vim.c file anymore. I need the notification to add some code of my own. if I choose the option without FREERTOS then the interrupt and notification code is generated but it is not there when I choose FREERTOS option. is this a bug or TI purposely remove HET notification when run with FREERTOS. I can't use vApplicationTickHook because this is too slow, I need some thing that run at 1usec period. is there a work around for this problem? I can try to add in the code manually but just wonder if there is some other setting that I might have missed. just don't want to have my manual code get wipe out the next time I decide to update tools in halcogen.

thanks

    Hello Hieu,

    Just tested. The HALCoGen generates NHET interrupt service routine if the freeRTOS is enabled or not.  The ISR void het1LowLevelInterrupt(void) is located in het.c rather than sys_vim.c.

    I use HALCoGen 4.06.01.
